Airtight dampers for servomotor

Dampers with actuator mounting are available in diameters of Ø80 to Ø630 mm,
including intermediate sizes. The actuator mounting is designed to enable
cladding with up to 50 mm thick insulation.

The DATML/DATM dampers are a good choice when the ductwork closure must be airtight.
The opening angle can be fixed with a mechanical limiter installed directly on the
actuator. The damper closure can be deflected by up to 2 cm when the air pressure
exceeds 2,000 Pa. For outdoor installations, the actuator must be protected from
UV light and weather.
