The ventilator consists of the telescopic air duct with an adjustable length regulated by position of the inner air duct inside the outer air
duct, the ventilation unit and the ventilation hood.
Two filters and the ceramic regenerator are located in the inner duct of the telescope.
The filters are designed to purify supply air and prevent foreign object ingress to the regenerator and the fan.
The ceramic regenerator uses extract air heat energy to warm up supply air flow.
The regenerator is equipped with a pull cord inside to facilitate its withdrawal from the ventilator.
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 unit is equipped with automatic shutters that shut the air
duct off during the ventilator standby and prevent air back draft.
The ventilation hood must be installed on the outer wall side. It is used for directed air discharge and prevention of ingress of water and
other objects to the ventilator.
VENTILATOR DESIGN
Outer air duct
Outer part of the
telescopic air duct.
Inner air duct
Inner part of the tele-
scopic air duct.
Ventilation unit
Is used to generate air flow by means of
the fan. The decorative grille protects the
fan against ingress of foreign objects
from the premises. The ventilation unit is
equipped with automatic shutters open-
ing when the ventilator is on and clos-
ing when it is off, thus preventing back
air flow.
Outer ventilation hood
Prevents direct water and foreign objects

Filter
Designed to clean supply air
flow and prevent dust and for-
eign objects ingress to the venti-
lator. The filters prevent regener-
ator soiling.
Ceramic regenerator
Provides extract air heat
energy regeneration to
warm up supply air flow.
Mounting plate
A mounting plate for installation
the ventilation unit on the wall
and connecting the ventilator to
power supply.
