Fig. 3. Unit design and operating logic
The single-room ventilator consists of a metal telescopic duct, ventilating unit with a decorative grille and an outer box, fig. 3.
The unit has a telescopic structure with adjustable length that is regulated by position of the air duct of smaller cross section inside
the air duct of larger cross section.
Two filters and the heat exchanger are installed inside of the inner telescopic duct. The heat exchanger provides utilization of thermal
energy contained in extract air for warming up of supply air.
The filters are installed on both sides of the heat exchanger, fig. 3 for cleaning of supply air and prevention of foreign object ingress
to the heat exchanger.

side of the premise.
