TwinFresh Comfo RA(1)-50(-2)

DESIGN AND OPERATING LOGIC 

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 two air filters 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 has a special heat insulation.
The ventilation unit must be installed on inner side of the wall. 
The outer ventilation hood is used for guided air discharge and prevention of direct ingress of water and other big objects to the ventilator.

VENTILATOR DESIGN 

Mounting plate 

A mounting box for 

installation the ventila-

tion unit on the wall and 

connecting the ventila-

tor to power supply. 

Outer duct 

Outer part of the 

telescopic air duct.

Outer ventilation 

hood 

Prevents direct 

ingress of water and 

foreign objects into 

the ventilator.

Filter 

Cleans the air flowing through the venti-

lator of dust and foreign objects and 

prevents contamination of the regenera-

tor. 

Ceramic regenerator

Utilises extract air heat 

energy to warm up 

supply air flow.

Ventilation unit 

Generates air flow by means of the 

fan rotation. The ventilation unit is 

covered with a ventilation grille on 

inner wall side to prevent ingress of 

foreign objects into the fan. The 

ventilation unit is equipped with 

automatic shutters to back draft 

prevention. The air shutters open 

during the ventilator activation and 

close during its shutdown. 

 

Inner air duct

Inner part of the 

telescopic air duct.

Air flow rectifier 

Prevents air turbulences 

in the ventilator.

Openings for humidity sensor

Provide contact of the humidity sensor with the 

indoor air for monitoring indoor humidity level.

Ventilator power indicator 

Shows operating status of the ventilator.

Filter replacement indicator.

Indicates the need to replace the filter. 

Infra-red receiver and light sensor

Responds to signals from the remote control and 

detects illumination level to activate/deactivate the 

night mode.
