to extract very high volumes of recirculated air
The aim of today’s clean air systems is to use a high proportion of recirculated air for ventilation in clean rooms. This is possible using the FFU modules positioned directly in the room which are installed as combined units in the false ceiling.
To be able to extract and filter such high volumes of recirculated air in a targeted manner the so-called filtering walls with HEPA filters are integrated in the extraction air wall area.
