WOLF’s CFL Edu decentralised ventilation unit has excellent heat recovery characteristics. The unit is easy to install directly under the ceiling, making it perfect for retrofitting into existing systems. The CFL Edu is also extremely quiet, which is vital for an effective learning environment. The high flow rate of approx. 1,000 m³/h provides high-quality air in line with today’s demanding requirements. The unit reduces the risk of infection to the absolute minimum.
Long-range nozzles are integrated into the CFL Edu to ensure that the supply air is distributed evenly around the room without an additional duct network. The reactive system is controlled using CO2 sensors. The CFL Edu can also be controlled with the WOLF WRS-K control system with remote access (LAN, WLAN, LTE).
The unit can also be integrated into a building’s central energy management system with the relevant interface modules.

Difficult site conditions for engineers and installers? WOLF offers just the right answer – the "Easy Lifting System". It makes handling onto or into a building much easier, as well as the installation of these functional units quicker and more accurate. It's so simple that even our largest components, such as thermal wheel or plate heat exchangers, can be easily brought into any building or onto the roof
The Easy-Lifting system also makes a major contribution to the hygiene of WOLF AHUs. Thanks to the sophisticated connection and transport technology, assembly-related leaks from heat exchangers or unit cubes can be virtually ruled out.
An industry-wide unique combination of configuration and production, allows flexibility in the configuration of the devices and at the same time an efficient production with particularly short delivery times.
There is currently no evidence to suggest that coronavirus can be spread through air handling and ventilation systems. Indeed, experts agree that good ventilation of indoor areas helps to keep the risk of infection down.
In addition to systems being technically up to date and planned and installed correctly, they must also be operated properly and serviced regularly for operation to be safe and hygienic. Where these points are carefully followed, air handling and ventilation systems pose no increased risk of infection according to the experts
As to the question of whether coronavirus can be filtered out using ventilation system filters, the first point to bear in mind is the size of viruses. Unlike bacteria, which, measuring 1-10µm are relatively large and can therefore be separated out efficiently by ePM1 fine dust filters, viruses are significantly smaller. The coronavirus measures approximately 0.16µm.
Having said that, viruses are generally attached to aerosols or dust particles. Transmission is primarily via droplets. Droplets that people produce are 0.5 to approx. 15µm in size. From other viruses it is known that a 1µm-droplet can contain a sufficient virus concentration to trigger an infection.
ePM1 filters separate out particles and aerosols, i.e. including droplets, down to a size of 1µm, depending on the separation efficiency. With higher separation efficiency, more of these droplets are separated out and thus remain in the filter medium.
When filters are replaced during servicing, personal protective equipment (PPE) should therefore always be worn. This is true irrespective of the current COVID-19 pandemic, as it is generally unknown what substances have been collected in the filter.
For the operation of air handling and ventilation systems during the COVID-19 pandemic, recommendations have been issued in a joint communication by the BTGA (Federal Industry Association for Technical Building Installations and Services), FGK (Association for Building and Indoor Air Quality) and RLT-Herstellerverband e.V. (AHU Manufacturers Association).
Fundamentally, continued good ventilation of indoor spaces is recommended, including in the current situation. Relative room air humidity should be between 30 per cent and 65 per cent. If the air humidity is too low, the sensitive mucous membranes in the upper airway are impaired, becoming more susceptible to viruses.
