Bacteria and virus-free room air in daycare centres

Trotec high-frequency air cleaners keep the room air germ-free in daycare centres

In kindergartens and similar childcare institutions of the childcare sector, infectious diseases are not uncommon. In addition to popular childhood illnesses such as mumps, measels, rubella, chickenpox, whooping cough and the fifth disease, diarrhoea and infections of the upper respiratory tract are also common. With the Coronavirus SARS CoV-2, another infectious disease entered our lives which is particularly challenging for child care workers. Even using spraying and wiping agents in a regular manner does not protect from the virus which mainly, in addition to smear and droplet infections, also spreads via the room air. In order to provide protection for children and employees, measures have to be taken to reduce the airborne risk of infection.

Group and play rooms require special attention

Children and room air have one thing in common: They both require special attention

Children need affection and closeness. Not only at home, but also in the day care centre and nursery or in similar childcare institutions. Therefore, child care workers cannot simply give up direct contact with children as they often have to be comforted and cuddled. However, this direct contact always carries the risk of an infection with airborne diseases. Influenza would be the most harmless case. In severe cases, it could also be e.g. Covid-19. Not only since Corona times it has been highly recommended to take additional hygiene measures in addition to the regular ones: The air in the room and particularly the air for breathing must be kept as clean as possible and free from bacteria and viruses. This serves to protect the childcare workers and the children, too.

Clean air for child care. Protects both personnel and children

Pathogenic viruses and bacteria are an invisible danger for every play group. The pathogens can survive in the room air for several hours, presenting a potential health risk with every breath. Current studies prove that e.g. the Sars-CoV-2 virus can stay in the air for several hours while remaining infective. The virus gets into the room air by means of aerosols that are emitted when breathing. Due to their light weight, these tiniest, but infectious particles float around in the air where they are inhaled by other children and present child care workers.

Half the number of children in play groups do not protect from virus-laden air.

It is an elementary component of hygiene concepts to divide children into separated groups in times of spreading epidemics. But no matter how small the groups are into which the children are divided: it does not prevent the virus from spreading through the air. Even using protective masks for mouth and nose does not entirely protect children and personnel from direct 'virus drizzle rain' caused by certain manners of talking. Protective masks definitely do not offer protection from germ-loaded aerosols 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. 

A child talking loudly is sufficient to have thousands of aerosols spreading into the room air per minute. The number even increases when care workers and children sing. Indeed, protective masks are 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! Such aerosol accumulations overcome physical barriers like sneeze guard barriers or separating walls. This is how particles of aerosol can easily access the respiratory tract or the eyes. The long time aerosols stay in the air are the reason for another problem: Since aerosols spread with air currents, the room air will be mixed every time the door is opened.

Protect child care workers and children with a 360-degree hygiene concept

Only a coordinated all-round solution of all possible hygiene measures and additional high frequency air purification reliably and permanently reduces the risk of infection. So don't only rely on physical separation, protective masks and washing hands regularly to protect children and child care workers. Just like children, 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 children

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 child care workers, children and parents.

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 kindergartens, day care or family centres 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 daycare centres and childcare institutions

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

Example 'playgroup': With an area of 6 x 5 m and a room height of 2.5 m, the depicted room has an air volume of 75 m³. One TAC V+ device is able to circulate this volume more than 21 times per hour (ventilation performance 1,600 m³/h), which corresponds to an air change rate (ACH) of 21.
Application scenario of the TAC V+ in daycare centres
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", creating zones filtered from viruses for playing safely in the surrounding air. Setting up several devices with some distance in-between will provide areas filled with clean air, even in large daycare centres. And due to its rollers, the position of the flexible TAC V+ or TES 200 can be changed in no time. This way, one device can be flexibly used for numerous rooms.

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, children 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. 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 kindergartens, day care and family centres or nurseries.
Attainable clean zone areas per air change rate

It is you who decides which safety level is best suited for your requirements in the daycare centre:

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 working radius 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. And even if a group of children requires higher protection measures e.g. because they belong to the risk group, the treatment for each clean zone area can be individually adjusted with any device by treating the respective zone in which the children stay.


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.
