The ventilation unit operates continuously, transports outdoor air and extract air at the
same time and guides and filters the outdoor air and extract air separately. The self-reg-
ulating fans (which ensure a constant volumetric flow rate) are arranged on the supply
air and exhaust air sides. The supply air fan (item 2 in Fig. 10) transports outdoor air
(item 4 in Fig. 9) through the outdoor air filter (item 5 in Fig. 10) and cross-counterflow
plate heat exchanger (item 3 in Fig. 10) into the interior as supply air (item 2 in Fig. 9).
The exhaust air fan (item 4 in Fig. 10) extracts the extract air (item 3 in Fig. 9) from the
interior. In the extract air filter (item 1 in Fig. 10), the extract air is cleaned, guided through
