Shut-off damper with pneumatic actuator

Consists of a DTU damper with a pneumatic actuator installed. The actuator consists of a glass-reinforced polyamide housing with an internal rolling diaphragm to which the spindle is fixed.

When air pressure rises, the actuator spindle is forced out and operates the blade via a lever. When air pressure falls, the actuator spindle retracts under the tension of the return spring. The damper blade is closed when delivered, and the actuator fully retracted.

There is a separate assembly, measuring, balancing and maintenance instruction for this product.

Ø 400–630 fullfills pressure class B in closed position.
