DTMU are tight-closing shut-off dampers. The dampers can be used to completely shut off the air flow.

The blade consists of double sheet metal with a intermediate sealing of EPDM-rubber, which is in contact with the inside of the damper housing when in the closed position.

DTMU is equipped with a handle and a locking mechanism for stepless adjustment of 0–90° without tools.

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

Ø 80–315 fullfills pressure class C in closed position.
Ø 355–630 fullfills pressure class B in closed position.
