Exhaust air fan
The hot exhaust air (A) of the space reaches the exhaust air filter (13) via the sound absorber (6) due to the suction
effect of the fan (16) through the exhaust air opening (4) of the air distributor module (5). It is cleaned there before heat
is removed from it in the heat recovery unit (12) and the exhaust air is passed on as outgoing exhaust air (B). The fan
conveys the cooled exhaust air via the sound absorber (8) through the exhaust air fitting (2) and the connected piping
to the outside.
The outdoor air (C) is drawn in by the fan (15) through the piping connected to the outdoor air fitting (1) via the sound
absorber (7). The outdoor air filter (10) cleans the outdoor air. In heat recovery (12), the outdoor air flows past the ex
-
haust air, but without mixing with the latter. In this case, the heat previously extracted from the exhaust air is supplied
