Function

Functional description
For airtight shut-off of volume flows in round plastic air ducts – typically for contaminated extract air in laboratories. The basic version is shut off by manually actuating the damper blade. Electrically or pneumatically operated actuators, which are available in different versions, can also be used to operate the damper blade. The versions differ with regard to the power supply and safety position (de-energised or de-pressurised state). Actuators with auxiliary switches for electrical monitoring of the damper blade position are also available.

The actuator of a damper blade must be controlled by a customer-side circuit and then moves the damper blade to the OPEN or CLOSED position.

Specification Text

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 6.02 in w.g.

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 C.
