Ceiling Swirl Diffuser Model DQJ Description The ceiling swirl diffuser type DQJ-Q/S-SR-... / DQJ-Q/S-SQ-... / DQJ-R-... is particularly suitable for installation in comfort rooms with high air change rates.

The diagrams clearly show the influence the blade position has on the radial propagation of the jet. The blades can be adjusted to achieve throw patterns from horizontal to vertical. This can be important, for...

Blade setting options Pages 5-8 in the catalogue clearly show the extreme adjustment flexibility of the DQJ-Q/S-SR/SQ type ceiling swirl diffusers. It may become necessary to adjust the position of the blades if, after installation, there are obstacles too close to the diffuser obstructing the air flow, for example columns or cupboards. The "two-way throw" version is ideal for corridors. This avoids any deflection from the wall down to the occupied zones.

Ceiling Swirl Diffuser Model DQJ Special model If, for constructional reasons (e.g. ceiling grid), a particular faceplate size has been defined, it is possible to punch a smaller swirl diffuser (1) into the faceplate. If a plenum box is required, it will be delivered, as a standard feature, in the same size as the punch and not in the size of the faceplate. However, if the plenum box is larger, on customer's special request, the standard hole (2) in the blade can be placed in the faceplate, to allow damper adjustment. In case of a screw mounting, the screw holes (3) are adjusted to the...
