Circular shut-off dampers in PPs plastic for air conditioning systems, available in 6 nominal sizes. Suitable for shutting off or restricting extract air flows containing aggressive substances since all components coming into contact with the airflow are made of plastic (no interior metal parts).
Suitable for duct pressures up to 1500 Pa.
Ready-to-install unit consists of the casing with a damper blade.
Spigot, suitable for ducts according to DIN 8077.
Position of the damper blade indicated externally at the shaft extension.
Closed blade air leakage to EN 1751, class 3.
Casing air leakage to EN 1751, class B.
