Virus-free room air in slaughterhouses and meat-processing factories

The high-frequency air cleaner TAC V+ reduces the airborne risk of infection in risky cutting and working zones via high-performance air filtration

Corona outbreaks in slaughterhouses and various meat-processing factories are a poignant reminder of how fast production procedures and whole companies can grind to a halt by infection chains if only one infected person is present among the entire staff, and if no effective measures have been taken to prevent airborne infections within the working zones. An important component for hygiene to prevent airborne infections is to keep the room air free from viruses by means of an effective air purification with high-performance filters such as those used in the professional high-frequency air cleaners from Trotec.

Infectious aerosols – risk factor for the meat industry

Many experts agree that the low temperatures necessary for cooling the meat, and the aerosols, which are responsible for the airborne transmission of particles, are the main reasons why the virus spreads so quickly when there are corona outbreaks in the meat-processing industry.

Infectious aerosol particles, due to their small size, would therefore sometimes float in the room air that is cooled down to a temperature between 6 to 10 °C in the cutting area of the plant for several hours and would be circulated permanently in the room by the ventilation system – and therefore be permanently inhaled! This finding is supported by other studies which also suggest that viruses in form of aerosol accumulations are particularly emitted when talking, partly remaining in the air for hours.

The problem as well as the solution both can be found in the air

If aerosols carrying viruses float in the room air of meat-cutting zones or other working environments of meat-processing factories, there is an increased risk of infection. Viruses don't stick to the distance rules, and overcome physical barriers such as separating walls with no problem. If the room air can be kept free from viruses, the airborne risk of infection will be minimised likewise.

Be on the safe side and use high-frequency air purification

Right from the start, Trotec's campaign and crucial measure is to fight aerosols in the room air. This is why we can offer you the first highly effective air purification unit with high-performance air filters and integrated virus decontamination! Your prime address for professional air treatment solutions.

Virus-free air virtually decreases the airborne risk of infection to zero

If the room air is largely kept free from germs and viruses, the airborne risk of infection will be minimized likewise in dangerous work zones of the meat and food industry.

Our Trotec high-frequency air cleaners such as the TAC V+ have been exactly designed to perform this task, for they efficiently and quickly reduce the intensity and time aerosol accumulations and suspended matter stay in closed rooms, thus creating a working environment with a substantially reduced risk of infection for all employees.

Exterminating aerosol accumulations within only a few minutes by high-performance air filtration

At the site of installation, the flexibly applicable high-frequency air cleaner is a mobile solution for creating clean zone areas that are flooded with purified air. Within this zone, the surrounding air nearly completely stays free of airborne germs and viruses because the TAC V+ is able to take in large volumes of contaminated room air and to carry out effective H14 HEPA high-performance air filtration. Moreover, the device is able to purify room air zones in a flexibly adjustable manner with clean air that has been filtered from viruses and aerosol particles.

This would even eliminate the risk of virus spreading posed by the downstream supply of this room air to existing ventilation systems for cooling and dehumidifying the air — if the viruses have already been filtered from the air supplied, there's no way that any virus can spread over ventilation systems.


High performance air cleaner TAC V+. Effective protection against aerosols and viruses in the air.

This product video will tell you all about the virus protection effect, the function and the advantages of the TAC V+ high-performance air purifier from Trotec. According to the current state of science, the coronavirus is transmitted in over 80% of cases by aerosols in the room air. The aerosols contaminated with viruses are produced when speaking, coughing or sneezing and often remain in the room air for a very long time. Inhaling the infectious aerosols can infect people in the room with pathogens. Trotec offers the solution for this: The TAC V+ high-performance air purifier filters the air with an efficiency of 99.995%, which corresponds to the air quality of operating rooms. The room air contaminated with aerosols is diluted, pressed to the floor, sucked in and filtered. In the vicinity of the air purifier, aerosol and virus-free clean air zones are created. The viruses bound in the filter are automatically killed by heat, so that the filter remains hygienically clean for a long time. By using the TAC V+ air purifier from Trotec, you will protect your employees, customers and guests. Ideal for, for example, restaurants, fitness studios, hotels, open-plan offices, medical practices, shops, and supermarkets, etc. So that finally more people, customers and visitors can stay indoors again without the risk of infection.

Effective air purification technology for clean breathing air

The aerosol accumulations are invisible to the naked eye and spread several metres into the room, flowing through interior spaces as swathes of fog do – see the following real-time video: The TAC V+ sucks in large volumes of potentially contaminated air near the ground, filters out nearly all viruses and suspended matter within minutes and generates clean air filtered from viruses which is guided back into the room. The result is that suddenly occurring accumulations of aerosol are diluted with clean air in your breathing area to such an extent that virus load and risk of infection will be significantly reduced! Just as the room is entirely foggy at the start of the video to be completely fog-free after the treatment in the end, the TAC V+ can also free your room air from particulate matter, fine particulates or aerosol accumulations carrying viruses.

High-performance air purification works exactly
where the greatest danger is lurking

In the meat industry, the coronavirus mainly spreads via the room air. This is due to the type of air conditioning that is usual in this line of business. The room air in the production areas is usually only cooled down and dehumidified, however, by air recirculation – meaning that no fresh air is supplied. Moreover, most plants are not provided with high-performance filtration. When there is even one spot in the room containing infectious viruses, conditioning by air recirculation and a lacking virus filtration act as a fatal tandem, rapidly spreading infectious viruses all across the room in the whole work area.

In fact, it's quite simple: without a virus there's no virus spreading

If we succeeded in keeping the room air free from viruses, the airborne infection risk would also be minimized. Even downstream cooling, dehumidification and repeated infeed of this air would then be safe, because the viruses have already been filtered from the air.

Trotec high-frequency air cleaners such as the TAC V+ have been exactly designed to perform this task, for they efficiently and quickly reduce the intensity and time aerosol accumulations and suspended matter stay in closed rooms, thus creating a working environment with a substantially reduced risk of infection for all employees.

High-performance air filtration provides for the creation of virus-free working zones

Directly at the installation site, the mobile air cleaner TAC V+ creates a "clean zone area", flooded with purified air and filtered from viruses. Within this zone, the surrounding air nearly completely stays free of airborne germs and viruses because the TAC V+ is able to take in large volumes of contaminated room air and to carry out effective H14 HEPA high-performance air filtration. Moreover, the device is able to purify room air zones in a flexibly adjustable manner with clean air that has been filtered from viruses and aerosol particles.

This clean air can then also be safely supplied to the internal air-conditioning system for cooling and dehumidification. Since the air supplied practically has already been freed from viruses in this way, the dehumidified cooling air can be safely returned to the room again.

Effective against bacteria and virus accumulations

Trotec high-frequency air cleaners are equipped with high-performance HEPA filters of class H14 which filter out more than 99.995 % of all fine suspended particles larger than 0.1 µm with a transmittance of only 0.005 %. Or in other words: No more than five of 100,000 particles pass the H14 high-performance air filter.

Thanks to this unique feature, these kinds of high-performance filters are also used in operation theatres or comparable hygiene-sensitive areas in order to produce clean air. In this way, you create optimum conditions to even keep the room and breathing air in slaughterhouses, cutting plants and other working areas in the meat-processing industry, where many staff members work in tight spaces, reliably free from viruses in times of spreading epidemics.

Well-known viral strains such as SARS-CoV, MERS-CoV or Covid-19 have a particle size of 0.005 to 0.1 µm. Most of the time, they form accumulations with other particles (such as saliva or suspended matter) which increases their size up to 0.4 µm or 0.5 µm. These accumulations are referred to as germs and will be filtered out reliably by the Trotec H14 high-performance air cleaning filters.

Without H14 high-performance filtration, virus-infected aerosols can spread over the ventilation system
With the high-frequency air cleaner TAC V+, virus-infected aerosols are filtered from the room air

The TAC V+ takes in the virus-infected air, filtering it with the HEPA technology whereupon they transmit it back to the room air

Neutralises virulent aerosol accumulations directly in the working zone

The TAC V+ is able to efficiently free the surrounding air in the working area of all employees from aerosols carrying viruses. By means of the high-frequency air cleaner, aerosols are filtered out with a circulating air performance in a very short time, resulting in the areas being permanently flooded with large volumes of virus-free room air. This significantly reduces the risk of infection in the treated zones.

Filter decontamination technology is unique in the world

This air cleaning performance is made possible by a synchronous system of efficient prefiltering and final particulate air filtration, provided by the integrated H14 high-performance air filter in compliance with EN 1822 (ISO 45H filter ISO 29463) by Trotec in a special heat-resistant version. The special filter included in the TAC V+ does not only hold back 99.995 % of all aerosol particles larger than 0.1 µm, i.e. no more than five of 100,000 particles pass the H14 high-performance air filter. This is the standard performance of the high-performance filtration in operating theatres. However, the TAC V+ provides even more efficiency by additionally heating up the Trotec H14 high-performance air filter in intervals which will inactivate all viruses remaining in the filter, serving for a 100 % decontamination of the filter.

The thermal self-regeneration function of the H14 special filter is unique in the world and exclusively available at Trotec! Thanks to this unique combination of filtration and decontamination technology, the TAC V+ reduces the airborne risk of infection in all dangerous working zones – ideal for slaughterhouses and other critical meat-processing production areas.

Effective HEPA filtration according to highest quality requirements that are obligatory for bacteria and virus filtration:

  • Each H14 high-performance air filter is tested individually and is assigned its respective serial number
  • The test report is enclosed as certificate in duplicate with each H14 high-performance air filter
  • The original test certificate can be filed with the documents for the device. If required, the copy can be attached to the air cleaning device.
  • Trotec H14 HEPA high-performance air filters are tested in compliance with EN 1822 and EN 60335-2-69

Why commercially available HEPA air cleaners are not sufficient for virus filtration in most cases

Large clean air capacity – high-performance filtration – filter decontamination – filter regeneration – noise level with large air volumes – versatility

Well thought out to a detailed level, unparalleled in its entirety: Because of these 6 advantages the TAC V+ – as is scientifically proven in several studies – ensures a technically effective and economically attractive solution to reduce the risk of infection by aerosols in closed rooms.


Large clean air capacity by high pressure and an optimum flow geometry

Only the TAC V+ has “the power to dilute”

The most important factor for reducing the risk of infection is the quick and effective dilution of infectious aerosol clouds directly at their place of origin, e.g. by a “Superspreader” – and draught-free and silently, in order to disrupt the operating procedure as little as possible! For this purpose large quantities of clean air, a high air pressure and an optimum flow geometry are required.

The TAC V+ offers all this: With a clean air volume of up to 1,600 m³/h, an optimum flow geometry and a flow pressure that is more than high enough, a circulation is established in the room within a very short time, ensuring that all the contaminated room air is effectively filtered.

Only air change rates that are sufficiently high minimize the risk of infection, this is scientifically proven. Where the effective treatment of the risk of infection by aerosol is concerned, high air change rates (exceeding a factor of 6) and therefore large volumes of clean air are indispensable, despite promises to the contrary made by other providers who advertise single to threefold air change rates per hour as sufficient.

Scientific studies have proven that the prerequisite for effective virus filtration is that the air cleaner used ensures a sufficiently high volume flow for the air change rate required, as is guaranteed by the TAC V+. In this context, the air change rate does not refer to a complete exchange of the air, but to the proportion of virus-filtered clean air that is supplied, relating to the room volume per hour.

High-performance filtration with a high filter efficiency

Only the TAC V+ is able to “effectively exterminate”

Heat-resistant H14 HEPA high-performance filter

Only H14 HEPA high-performance filters like those used in the TAC V+ can even filter the small-sized virus-carrying aerosols (0.1 - 0.2 µm) from the room air, and this at a rate of 99.995 %. Therefore the filter efficiency of H14 HEPA filters is 10 times higher than that of H13 HEPA filters with 99.95 %, as used in most air cleaners!

99.995 % or 99.95 %? This may not sound like a lot, but exactly these two decimal places make the big difference between H13 and H14 HEPA filters! Virus-carrying aerosols are extremely tiny. And “virus filters” are designed to “filter viruses”. That’s why the TAC V+ not only filters the large, but also the small-sized, highly infectious aerosols from the room air which are not even filtered out by FFP2 and FFP3 respiratory masks and therefore don’t offer genuine protection. Maximum safety is only ensured by H14 HEPA filters!

Scientific studies, however, qualify that a filter performance beneficial to the decay rate pursued can only be confirmed if the volume flow of the air cleaner and the flow speed in the particulate air filter are sufficiently attuned to one another by an adequately dimensioned filter surface, a property which at present cannot be achieved with any other mobile air cleaner than the TAC V+!

Yet, H14 HEPA filtration alone still does not provide hygiene protection to a full extent. After all, the viruses have not disappeared, they are only caught in the filter, but still active and still infectious over a longer period of time. At the latest when the filter has to be changed during ongoing operation, an extreme health hazard is posed to the staff, customers, guests, employees, etc. Therefore indispensable: Thermal filter decontamination …

Thermal filter decontamination – 100 °C for 100 % safety

Unique technology – Trotec exclusive

Fully encapsulated H14 high-temperature particulate air filter, equipped with heat-conducting metal lamellae

Only with the TAC V+ and TES 200 the special, fully encapsulated H14 high-temperature lamellae particulate air filter is thermally treated and heated to over 100 °C at regular intervals. Specially for this purpose, the filter has been developed and provided with heat-conducting metal lamellae.

This thermal filter decontamination technology is available exclusively at Trotec and offers you several unique benefits at the same time! By heating the filters, the proteins of the viruses filtered out, which are relevant to the infectiousness, are denatured, and the viruses are practically destroyed. Therefore infectious viruses can no longer enter the ambient air from the filter, for example by improper handling Furthermore, bacteria, germs and other microorganisms are additionally destroyed.

This means that 100 % employee protection can be ensured during operation and also when the filter is changed!You could say, this is the “virus airbag” for more safety. It is there when you need it – and as long as nothing happens, you won’t even notice it.

Without thermal filter decontamination an air cleaner quickly becomes a virus spreader, this is also confirmed by research

Scientific studies substantiate the mandatory prerequisite of thermal filter decontamination to ensure effective virus filtration. In fact, Prof. Dr. Christian Kähler explicitly points out this mandatory provision in his study: “To prevent the room air cleaner from becoming a virus spreader, the H14 filter should be heated to approx. 100 °C every day for about 30 minutes, in order to destroy the viruses in the filter and prevent the formation of biofilms, bacteria and fungi without using harmful chemical additives or UV-C radiation.”

Thermal filter regeneration – hygiene protection, also from inside

No filter humidity, no filter mould and at the same time a much longer filter lifetime

Thermal filter decontamination and thermal filter regeneration

Aerosol separators and virus air cleaners take effect where many people are present in narrow spaces over a longer time and exhale larger quantities of aerosols. Aerosols, whether virus-carrying or not, for the greater part consist of micro droplets – pure water, that is. Customary H14 filters may be able to “catch” these humid aerosols, however, they also catch additional problems. Since the increasing humidity in the filter causes it to start fouling more quickly. As a result, the filter resistance increases, constantly reducing the amount of clean air emitted and thus significantly reduces the filter lifetime. The fast fouling of filters at high loads of aerosols has been scientifically proven by field tests.

Moreover, the constantly high level of humidity favours the formation of filter mould or biofilms. Instead of eliminating a hazard, others may therefore be created. For example, a decreasing flow rate, shorter filter lifetimes and mould on the filter. Because the filter is heated to over 100 °C regularly, the entry of moisture, fast fouling and filter mould are not a problem with the TAC V+. Since the humidity is fully discharged again in the course of the thermal regeneration cycle, not only drying the filter at regular intervals, but additionally regenerating it again via its self-cleaning function.

With this innovative procedure the filter resistance remains low and the clean air flow remains at a constantly high level for a considerably longer time. Consequently the lifetime is much longer than that of other filter systems without thermal regeneration and decontamination. This is also confirmed by current studies, providing the following summary that is based on the analysis of the TAC V+ and its H14 HEPA filter with self-cleaning function: “Therefore it is to be expected that this filter can have a lifetime of several years, depending on the load.”

Hard to believe, hardly to be heard

The TAC V+ is an an air cleaning revolution of the silent kind

Sound protection hood to ensure silent operation

The task of qualified high-performance air purifiers is to make the utilization of interior spaces possible again – and not to make it more difficult! Nevertheless, without large volumes of clean air, the risk of infection cannot be minimized!

When aerosols are separated or viruses are filtered out, high air change rates between 6 and 12 are required, and in the medical sector up to even 20 times. Without these large air circulation rates, spontaneously occurring aerosol clouds cannot be diluted and filtered out safely and quickly. Therefore, depending on the safety requirement, even in smaller rooms of 45 m² you already need amounts of clean air from 700 m³ to 1,500 m³, which requires a fan with a correspondingly high ventilation power. In addition to the required filter efficiency and long filter lifetimes, however, an acceptable noise level, in spite of the large air volumes, is desirable.

The TAC V+ is the first and so far the only room air purifier on the global market that has been explicitly designed for the filtration of virus-carrying aerosols in interior spaces! That’s why a long filter lifetime and low noise generation were two of the key priorities of the design. For noise-sensitive areas, the TAC V+ can be equipped with an optional sound protection hood, if required, reducing the subjectively perceived noise by almost 50 % yet again!

Virus protection on the spot

The TAC V+ is flexible, mobile and can be used everywhere at any time

Its unique design makes it possible to use the TAC V+ everywhere it is needed and without any installation effort. Flexible, mobile and with its modular design, exactly as many TAC V+ can be provided as required by the hygiene concept. Variably adapted to the staff density, security level, type of application and room size. With the optionally available hose adapter, the TAC V+ can also be connected to existing air distribution systems.

Recommended by scientists: Only sufficiently dimensioned air change rates ensure protection against a risk of infection

Where the effective treatment of the risk of infection by aerosol is concerned, high air change rates (exceeding a factor of 6) and large volumes of clean air are indispensable, despite promises to the contrary made by other providers who advertise single to threefold air change rates per hour as sufficient. To meet these requirements, the virus air cleaner not only has to be able to provide corresponding volumes of clean air, but it must also be flexibly placeable directly in potential hazard zones.


Well thought out to the detail, unparalleled in its entirety – the six benefits of the TAC V+ at a glance:

  1. Large clean air capacity: up to 1,600 m³/h virus-filtered clean air, a high pressure performance for optimum air circulation and high air circulation rates
  2. High-performance filtration: Fully encapsulated H14 lamellae high-temperature filter “made in Germany” with flow-adapted filter surface for virus-filtered room air
  3. Thermal filter decontamination: 100 °C for 100 % elimination of viruses, bacteria and other microorganisms, preventing the air cleaner from becoming a virus spreader itself!
  1. Thermal filter regeneration: 100 °C for 100 % evaporation of the aerosols; self-cleaning of the filter, low filter resistance, constantly high volume of clean air, extremely long lifetime, no filter mould
  2. Background noise: the most silent high-performance air purifier in relation to the air flow rate
  3. Application flexibility: suitable for mobile and stationary application, “Plug & Play” for the connection to existing air distribution systems, modularly expandable

The TAC V+ is the only air cleaner on the market with a scientifically proven virucidal effectiveness!

Recent studies have established that the high-frequency air cleaner TAC V+ effectively reduces the airborne infection risk

As the only mobile air cleaner worldwide, the TAC V+ was specially designed for the purpose of virus filtration and in this regard has been tested for its effectiveness by several scientific studies. A study conducted under the direction of Prof. Dr. Christian Kähler at the Institute for Fluid Mechanics and Aerodynamics of the University of the German Federal Armed Forces in Munich has confirmed that by means of the TAC V+ the virus load brought on by aerosols and therefore an airborne infection risk in interior spaces can be substantially reduced even with the windows closed and without a proper room ventilation system.

Studies prove: The TAC V+ can effectively reduce an indirect SARS-CoV-2 infection risk brought on by aerosols!

“The quantitative measurement results show that, with the TROTEC TAC V+ room air cleaner tested, due to the large volume flow and the filter combination of class F7 + H14, aerosol concentrations even in rooms with a surface of 80 m² can be reduced by half within 6 - 15 minutes, depending on the volume flow. In the case of rooms of 20 m² the concentrations are halved within 3 - 5 minutes, depending on the volume flow.

Therefore, room air cleaners of the TAC V+ type make it possible to easily maintain the aerosol concentration in small-sized to medium-sized rooms at a low level. … Air purification units of the TAC V+ type are therefore perfectly suited, for instance, to provide for a constantly low virus load in classrooms, shops, waiting or treatment rooms, without having to think about opening windows and affecting the well-being in the room. Furthermore, in contrast to free ventilation by means of windows they also ensure a true reduction of the virus load, something that free ventilation can often not guarantee.

In addition and compared to room ventilation systems working without or only with a small proportion of fresh air, they also offer the benefit of ensuring that the viruses are actually filtered out and that they are not spread within the building through other channels. … To prevent the room air cleaner from becoming a virus spreader, the H14 filter should be heated to approx. 100 °C every day for about 30 minutes, in order to destroy the viruses in the filter and prevent the formation of biofilms, bacteria and fungi without using harmful chemical additives or UV-C radiation.“

In an interview with the news magazine “Spiegel”, Prof. Dr. Kähler summarizes his research results on the TAC V+ as follows: »If you run this system continuously, no one will manage to generate an aerosol concentration of an infectious level in a room!«

The TAC V+ from Trotec is the only mobile air purification unit provided with a special H14 high-temperature lamellae particulate air filter with thermal filter decontamination, with which the H14 HEPA filter is treated thermally at regular intervals and is heated to over 100 °C, a procedure which practically destroys all viruses filtered out and which, by scientific expertise, is therefore defined as absolutely indispensable for effectively purifying the air from viruses! Only the combination of an effective F7-H14 filter system, a perfectly balanced air volume flow and the exclusive thermal filter decontamination technology provides for an effective protection against infections!

Triple indicator for healthy room air: Our BQ air quality measuring devices indicate all important values

Particle measuring device BQ30 for air quality monitoring

The Air quality monitor BQ30 should not be missing on any teacher's desk or in any open-plan office because this environmental monitoring station shows you the most important values for healthy room air at a glance: In addition to current CO2 values and the prevailing climate data, the pollution with particulate matter is also displayed in the particle sizes PM2.5 or PM10.

The CO2 load is an important indicator for required ventilation measures and the determined fine dust particle sizes also include pollen, a helpful feature to monitor the air quality for allergy sufferers!

Since critical aerosols which could be contaminated with viruses and remain suspended in the air for a long time also have particle sizes of 2.5, the BQ30 is the device to allow you to monitor the current aerosol load in the room. In addition, the device provides the function to configure individual limit values for all parameters, and if these are exceeded, the device automatically displays an alarm.

The Particle measuring device BQ20 rather is a mobile solution and can be recommended for e.g. caretaker work to be able to determine the aerosol load of the room air in different rooms.
