Functional description
For airtight shut-off of volume flows in round air ducts. 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.
Nominal sizes | 100 – 400 mm |
Acceptable static differential pressure | 1500 Pa |
Operating temperature | 10 – 50 °C |
