Air cleaners for virus filtration in restaurants, taverns and canteens

In case of aerosol accumulations in the room air, simply set up the device. The professional high-frequency air cleaners by Trotec provide for clean air for both guests and personnel

The shutdowns as a result of the corona crisis brought an existential threat to restaurant proprietors in particular. Reserves are exhausted, time is running, and with the regulations gradually being relaxed, the question remains on how to set up efficient hygiene concepts to protect personnel and guests. Restaurant proprietors are already very familiar with the subject of hygiene, knowing all of HACCP to LMHV. However, dealing with airborne viruses and respective protective measures for own guest rooms and customers might present a fairly new situation for any restaurant proprietor, chef de cuisine or canteen operator. 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 professional solutions such as the high-frequency air cleaners by Trotec.

Airborne pathogens require additional protective measures in the gastronomy sector

Prevent the landlord from becoming a host

If attached to aerosols, viruses such as Sars-Cov-2 can survive in the room air for several hours. As various scientific studies prove, this is how they remain infectious. This trait also applies to other pathogens as well, e.g. to influenza viruses. With the increasing number of persons in the guest room, the danger rises to become infected with pathogens by inhaling the air in the room. Only one infected person who does not even know about his or her infection is enough to make the restaurant an infection hotspot.

Separating walls are a start, but don’t help much against viruses

The problem of freely floating aerosols with viruses being attached to them is exactly what it is: They are floating! This is why separating walls are only suitable for separating persons, not virus-laden air. Protective screens or separating walls alone, e.g. installed in-between tables, do not prevent viruses from spreading through the air. Separating walls made of Plexiglas, similar constructions and also protective masks for mouth and nose indeed protect from direct ’virus drizzle rain’ caused by certain manners of talking. However, they do not provide protection from germ-laden aerosol particles that are released into the room air while talking and breathing, where they will continue floating in the form of aerosol accumulations for several hours.

Infectious viruses seem to not get enough of healthy guests

Combining the use of masks and separating walls is a first important approach to reduce the risk of a direct droplet infection with the SARS-CoV-2 virus. However, this measure does not protect from a far greater danger of infection – accumulations of aerosol particles floating freely in the room air!

After all, airborne viruses are not familiar with social distancing rules: Even talking persons emit both large visible droplets as some sort of ’virus drizzle rain’ and, on a much larger scale, tiny aerosol particles, invisible to the eye and contaminated with viruses or bacteria if from infected persons. If only one person in the room becomes infected, the owners risk their restaurant to be closed again by the respective authorities – even if the restaurant had just been opened.

Aerosol accumulations spread like billows of smoke, only invisibly

The accumulation of aerosol consists of simultaneously emitted microfine droplets, comparable to billows of smoke. The particles will spread for several metres up and far across the room which is why they overcome physical barriers of sneeze guards barriers or separating walls with no problem. As a result, they can get that easily into the respiratory tract and eyes of other people staying on the other side of the separating wall.

Prevent your business from getting shutdown again with a 360-degree hygiene concept

Only a coordinated all-round solution with a direct sneeze guard barrier or a separating wall and additional high frequency air purification reliably and permanently reduces the risk of infection. For this reason, don’t only rely on physical barriers such as protective masks for mouth and nose and separating walls for protecting your employees and guests. Aerosol particles in the room air don’t stick to the distance rules – as they potentially transport viruses, they are the real source of danger! This is why the main objective is to prevent breathing air of all guests from spreading throughout the room.


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

If the room air is kept free from germs and viruses, the airborne risk of infection will be minimised likewise. Trotec high-frequency air cleaners such as the TAC V+ are 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, creating zones with an extraordinarily reduced risk of infection for both employees and guests.

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 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.

Effective against bacteria and virus accumulations

Trotec high-frequency air cleaners are equipped with 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 filter. Thanks to this unique feature, these kinds of high-performance filters are also used in operation theatres or comparable hygienically sensitive areas in order to produce clean air. This way, you create optimum conditions to keep room air and breathing air free from germs and viruses in restaurants, dining rooms and canteens or other highly frequented areas with a lot of public traffic 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 air cleaning filters.

All H14 HEPA filters by Trotec fulfil the highest quality standards that are obligatory for bacteria and virus filtration.

  • Each H14 high-performance filter is tested individually and is assigned its respective serial number
  • The test report is enclosed as certificate in duplicate with each H14 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.
  • HEPA high-performance H14 filters are tested in compliance with EN 1822 and EN 60335-2-69.

Also suitable for any TAC air cleaner with H13 filter

You can also insert a H14 HEPA filter by Trotec into your TAC air cleaner if you already possess a TAC device. The H14 filters are available as an accessory, e.g. for the professional air cleaners TAC 3000, TAC 5000 or TAC 6500. Simply replace the H13 filter in the filter compartment with a H14 HEPA filter.

Professional air cleaner with H14 HEPA filter by Trotec

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.

Aerosols and the corona virus: This is how the virus spreads through the indoor air

While larger droplets do not fly far when speaking and quickly sink to the ground, the smaller and lighter aerosols float in the air for several hours and are distributed throughout the room. The TAC V + air purifier offers reliable protection against infectious aerosol particles. The room air is cleaned with high frequency and infectious viruses are filtered out and inactivated in the new HEPA filter.

Our recommendation for virus filtration in restaurants, taverns and canteens

The TAC V+ or TES 200 Trotec air cleaners for purifying areas

The TAC V+ or TES 200 take in the virus-infected air, filtering it with the HEPA technology whereupon they transmit it back to the room air.

The vertical construction of the mobile high-frequency air cleaners TAC V+ and TES 200 serves for establishing particularly efficient “clean zone areas” with surrounding air filtered from viruses. Setting up several devices with some distance in-between will create areas filled with clean air, providing service zones or zones for eating and resting with a low aerosol concentration.

Along with good food, it is normal to have merry chats and to laugh a lot. However, with every sentence uttered, with every laugh, even while exhaling, aerosol particles carrying viruses can be released into the surrounding air where they continue to present a high risk of infection for several hours.

High-frequency air purification eradicates accumulations of aerosol particles in minutes

By deliberately positioning several high-frequency air cleaners of type TAC V+ or TES 200, guests, waiters and waitresses, cooks and other employees working in all kinds of servicing and dining areas will be way better protected from suddenly appearing droplets and accumulations of aerosol particles. These will be filtered out within the shortest time due to the high air change rate. Besides, areas will be permanently filled with large amounts of virus-free room air which will significantly reduce the risk of infection in the “clean zone area”.

H14 special filter with thermal self-regeneration function

This air cleaning performance is made possible by a synchronous system of efficient prefiltering and final particulate air filtration, provided by the integrated H14 HEPA filter by Trotec in a special heat-resistant version. This special filter is integrated in the devices TAC V+ and TES 200 and is heated up 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!

TAC V+ and TES 200 are part of the same assembly and therefore provide the identical fan performance and HEPA air purification function. Along with the HEPA air purification, the TES 200 can, however, also be used for combined room heating, thermal decontamination of rooms and surfaces and thermal pest control. The reason for this are the additionally integrated, powerful electric heating module and enhanced programming options for various air treatment scenarios.

Thanks to their combined technology of filter and decontamination techniques which are unique in the world, TAC V+ and TES 200 provide safety by reducing an airborne risk of infection in all areas with a lot of public traffic – ideally suited for restaurants, taverns, canteens or dining rooms!

Always a good investment – even in “post-corona times”

With an TAC V+ or TES 200 the room air is not only cleaned, but also filtered from odours.

Good food simply smells and tastes fantastic. But once hunger is appeased, the smell will sometimes stay longer. Whether odours of food, beer and strong alcoholic drinks, sweat and maybe nicotine – a lot of suspended matter in the air absorbs these unpleasant odours. If the air is not sufficiently purified, they will permanently attach to textiles, carpets, wallpapers, interior decoration etc.

On top of filtering viruses, the high filter efficiency of the H14 HEPA air purification also guarantees to neutralise odours by filtering suspended matter carrying these odours. The result is clean room air all around!

Example restaurant: With 100 m² of space and a height of 3 m, the guest room shown has an air volume of 300 m³, which two TAC V+ can filter almost 11 times per hour virus-free (air output 3,200 m³ / h) – this corresponds to an air exchange rate (LW / h) of 11 (clean air volume of 66.6 m³ per guest with 48 occupied seats).
Application scenario of the TAC V+ in a restaurant

It is you who decides which safety level is best suited for your requirements:

The higher the air circulation and the respective air change rate (ACH), the lower is the time viruses stay in the room air, which results in the infection risk decreasing. The number of the air change rate is also the factor for determining the operating range of each high-frequency air cleaner.

5 ACH achieve basic protection. However, we recommend using air change rates between 10 and 20 ACH for fully occupied rooms in order to obtain significant risk protection. After all, the main objective is to prevent breathing air of different persons from spreading as effectively as possible. After all, the main objective is to prevent breathing air of different persons from spreading as effectively as possible. And even if a guest asks for higher protection measures e.g. because he or she belongs to the risk group, the treatment for each clean zone area can be individually adjusted with any device treating the respective zone in which the guest stays.

Optionally also available in further colours

In addition to the standard yellow paint, the TAC V+ is optionally painted in basalt gray, white or bronze and can also be ordered as a stainless steel version.
