HMK - Reactive diffuser plenum box

Plenum box HMK is used for hidden ­installation of ­reactive supply air diffusers in a ­suspended ­ceiling system. The diffuser box is sound ­absorbent and equipped with a damper for ­adjustment. The diffuser section is installed in the plenum box with bayonet fitting.

Available for duct dimension 250 mm. The full name for HMK is HMK-250/400.

HMK is equipped with nipple for pressure measurement. Current flow from the diffuser can be easily checked by multiplying the measured pressure in Pa by 10.
