E-CRQ: Single-blade 150 mm aluminium flow regulating damper, designed to be inserted into rectangular ducts mounted in low false ceilings. The damper size, including the two 19 mm "U" shaped tabs on the frames, has a total fixed height of 187 mm. The maximum recommended width for this type of damper is 800 mm.

The E-CRQ damper is supplied with a manual control but can be motorised at 24 or 220 V to be mounted with the RADIOTACTIL Zoning System or with a two-position thermostat or switch.

E-CRQ fibre profile If the gate is connected to a fibreglass duct, it is possible to supply a "T" type profile which, when fitted to the outer frame of the E-CRQ, converts the 90º flanges of the frame into a straight neck to connect to the fibre duct.
