EKO-DRHU
Adjustment damper with motor shelf

Ø 80–1000 is made up of a DRU damper with an attached KOMHY combi motor shelf. The damper lacks a knob and has an extended shaft to avoid the need for the knob extender VREDF. Has a swivel cut blade. The blade is continuously adjustable 0–90°. The damper allows an insulation thickness of approx. 50 mm. The blade is designed so that the least possible noise is generated. The sound is about the same as that of a perforated blade. But the blade is less susceptible to clogging because it has no perforation.
