DKQ - Quarter-Round Nozzle Duct
Quarter-round nozzle duct for suspended ceilings
DKQ is a nozzle duct for wall/ceiling corners. Available in dimensions 160mm – 400mm. The units are manufactured in lengths of 0.5, 1, 1.5, 2m and can be assembled into long units, 20-30m and sometimes even longer.
For classrooms, the DKQ is perfect if you want to install the unit along the wall. For Engelska Skolan in Falun and Älvsjö, we have delivered quarter-round diffusers that are 7.5m long in dimension 315, capable of handling just over 300 l/s without draft or noise issues.
Duct casing is available as an accessory.
