Bacteria and virus-free room air in waiting rooms and medical practices

Trotec high-frequency air cleaners keep the room air germ-free in waiting and treatment rooms

The one who sees the doctor in times of a spreading influenza, of gastrointestinal infections or similar infectious diseases usually has to share the waiting room with sniffling, coughing or even febrile persons sitting next to him. Going to the dentist or the eye specialist also provides the same risk potential if e.g. a large part of the population is affected by an influenza epidemic. Not a pleasant thought, and some patients consequently won't see the doctor just when it was reasonable and necessary. The result of pure fear to catch an infection of even more dangerous illnesses such as SARS-CoV-2, norovirus or MERS-CoV in a waiting or treatment room. These people have good reason to be anxious. A lot of infectious diseases like influenza, gastroenteritis and Covid-19 are transmitted via droplets and smear infection. Even spraying and wiping good quality disinfectants meticulously and regularly does not help if the harmful pathogens are literally flying around in the air.

Waiting and treatment rooms require special attention

Waiting and treatment rooms require special attention

For this reason, it is particularly indispensable to keep room and breathing air of medical practices and fully occupied waiting rooms – with an increased risk of infection – maximally clean and free from suspended matter and pathogenic microorganisms, all in addition to the disinfection of medical instruments and of the most diverse surfaces. This serves to protect the employees but also the mostly elderly patients that are part of the risk group due to their weakened immune system.

Clean air is crucial for a successful treatment

Pathogenic viruses and bacteria are persistent and survive quite some time in the room air. Studies have shown that e.g. the Sars-CoV-2 virus can stay in the air for several hours while remaining infective. And every additional patient entering the waiting room increases the invisible risk of infection for the other people sitting in the room.

Separating walls only separate people, not virus-infected air

Protective screens or separating walls alone, e.g. installed at the reception, 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.

In fact, 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. Nevertheless, this measure does not protect from a far greater danger of infection – talking persons emitting accumulations of aerosol particles which will then freely float in the room air. Such aerosol accumulations overcome any kind of sneeze guard barrier or separating wall with no problem. This is how particles of aerosol can easily access the respiratory tract or the eyes of other people staying behind the separating wall.

Protect employees and patients 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 personnel and patients. 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!


High-frequency air purification protects both personnel and patients

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 patients and personnel.

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 in waiting and treatment rooms free from germs and 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 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 waiting rooms and practice premises

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

Example of a waiting room: With an area of 6 x 6 m and a room height of 2.5 m, the depicted waiting room has an air volume of 90 m³. One TAC V+ device is able to circulate this volume more than 18 times per hour (ventilation performance 1,600 m³/h), which corresponds to an air change rate (ACH) of 18.
Application scenario of the TAC V+ in a waiting room
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 provide areas filled with clean air serving as both passage zones or treatment or waiting zones with a low aerosol concentration.

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, patients and personnel 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 highly frequented medical practices and waiting rooms or therapy and treatment rooms.

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.


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.
