RD-S is a circular adjusting damper with sealing gasket and mechanism for actuator.
The circular damper is used to regulate the air flow on the branches of ventilation and air conditioning systems.
The damper is equipped with an inner blade, a sealing gasket and a mechanism for connecting the servomotor.
For a good seal the damper is equipped with a rubber gasket at both ends and on the inner blade.
When the air pressure exceeds 2000Pa the damper closure can be deflected by up to 2cm.
For outdoor installations, the servomotor must be protected from UV light and weather.
The actuator mounted on the damper allows the application of insulation with thickness of up to 50 mm.
Dimensional range: Ø100, Ø125, Ø160, Ø200, Ø250, Ø315, Ø355, Ø400, Ø450, Ø500, Ø560, Ø630.
