Page 7: Design And Operating Principle
DESIGN AND OPERATING PRINCIPLE Warm stale extract air from the room flows into the unit, where it is filtered by the extract filter, then air flows through the heat exchanger and is exhausted outside by the exhaust fan. Cold fresh air from the outside flows into the unit, where it is cleaned by the supply filter. Then the air flows through the heat exchanger and is directed to the room with the supply fan. - Page 8 DVUT 1000 PB EC V.2 Service side view DVUT 1000 PB EC DVUT 1000 PBE EC DVUT 1000 PBE2 EC Extract filter Supply filter Exhaust fan Supply fan Heat exchanger ...
