Functions
The damper is used to exhaust air according to the actual need (for BOOST mode ventilation). Inside the body of the damper there are two opposing closing leaves, which are connected by a rod that is controlled by a servo drive. When one flap leaf closes, the other leaf opens. The servo drive can be supplied with a 24 V AC/DC or 230 VAC power supply.
Mounting
The damper can be installed in any position (horizontal, vertical) on a wall or ceiling. Service access must be provided for the damper actuator.
