Swirl diffuser DQJF Variable volumetric flow Description The swirl diffuser type DQJF is an air diffuser that is suitable in particular for suspended use in industrial halls and comfort rooms of high air change rates. Unlike the conventional swirl diffusers, the built-in blades can also be adjusted at a later stage. This modification can be necessary, for example, if obstacles obstruct the air jet or if high air velocities occur in areas where this is not desired. The air jet can be deflected from the horizontal to the vertical direction by adjusting individual blades. This can be important,...
