DESIGN AND oPERATING PRINCIPlE

The ventilator consists of an air duct, a ventilation unit and an outer ventilation hood.
Two filters, a regenerator, a distance ring and two air flow rectifiers are installed in the air duct.
The air filters are designed to purify supply air and prevent foreign object ingress into the heat exchanger and the fan.
The regenerator utilises extract air heat energy to warm up supply air flow.
The regenerator is heat insulated with a specially designed insulating material.
The ventilation unit must be installed on inner side of the wall.
The ventilation hood must be installed on outer side of the wall. It is used for directed air discharge and prevention of ingress of water
and other objects to the ventilator.
Polyurethane foam
Provides tight contact between the
ventilator parts
The ventilator operates in two cycles, 70 seconds each.
CYClE I. Warm stale extract air flows through the regenerator, which is gradually warmed up and moisturized. In 70 seconds as the
regenerator gets warmed up the ventilator is switched to supply mode.
CYClE II. Fresh intake air from outside flows through the regenerator, absorbs accumulated moisture and is heated to a room temperature
due to the heat accumulated in the regenerator. In 70 seconds as the regenerator gets cooled down, the ventilator is switched to air
extract mode and the cycle is renewed.

Air duct
Cleans supply air flow and prevents
ingress of dust and foreign objects
into the ventilator.
Prevents contamination
of the regenerator.
