Supply Air Filter
(Lifa TJ 3G Filter)

Supply air filter, Supply air filters 3G HEPAeSORB Filters are designed to maintain healthy indoor air by preventing typical airborne contaminants, like particulate matter, VOCs, ozone, and odours, from entering the room air. They are installed as an integrated part of the ventilation system.

Patented 3G technology enables high filtration efficiency combined with very low pressure drop ( P/Pa), leading to both very high and long lasting loading capacity.

All TJ models are equipped with electric charger and UV-light in order to guarantee 100% microbe-killing efficiency.

Can be integrated into building automation systems (e.g. LON local operating network)

Lifa 3G Filter is developed mainly for airborne contaminants typical in urban environments. It is designed is to prevent contaminants such as fine particles, volatile organic compounds (VOCs), ozone and odours from entering room air and to maintain healthy indoor air quality. Thanks to its high filtration efficiency, it provides heightened, although not complete protection against biological agents. Moreover, it removes also some chemical agents with low vapour pressure such as sarin and mustard gas. However, due to the high toxicity of the biological or chemical agents it is recommended that Lifa 3G Filter is not used alone as a security filter. It is an ideal prefilter for High Security Filter, extending the service life of the much more expensive Carbon-filter.

3G Filter system to be installed as an integrated part of the ventilation system.

When the system (LIFA TJ 3G) is used whitout the charger then the efficiency might reduce. The use of the centralized charger needs special instructions from the manufacturer. Systems are installed as an integrated part of the ventilation system. Systems can be installed as an integrated part of the ventilation system and supported as necessary to the roof. LIFA TJ 3G Filter system do not have a blower/fan. System has to be connected to electricity in those models including a charger. Filtration efficiency has been measured for particles (> 0,1 µm) and gases. UV-light can be installed separately as an accessory to models including a charger.
