The ventilator consists of a telescopic air duct with adjustable length (inner part and outer part), a ventilation unit and an outer ventilation
hood. The inner telescopic part contains one or two air filters, depending on the ventilation model and a ceramic regenerator.
The air filters are designed to purify supply air and prevent foreign object ingress into the regenerator and the fan. The ceramic regenerator
utilises 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 installed on an insulating layer used as a sealer as well.
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.
TwinFresh S-60 and its modifications are not equipped with automatic shutters.
The outer ventilation hood is used to prevent direct ingress of water and other objects to the ventilator.
