Shut-off damper with pneumatic actuator

Consists of a DTU damper with a pneumatic actuator installed. The actuator consists of a polyamide housing and metal parts of stainless steel.

When the actuator's control pressure increases, the actuator opens the damper blade. When the actuator's control pressure decreases, the actuator closes the damper blade, by using the spring inside the actuator. The damper blade is closed on delivery.

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