Model WQA-R-... - WQA-...-L/R-... -WQA-...-...-FT-...-WQA-...-...-LV-...-WQA-...-H-FV-...- Wall Displacement Diffuser Model WQA Description Large rooms such as industrial halls in which high amounts of harmful substances are produced are best ventilated by means of a low-turbulence displacement air flow (displacement ventilation). This is due to the fact that in low-turbulence displacement air flows the supply air enters the room at low velocities (approx. 0.2 m/s). The fresh air sinks to the floor, spreads itself and displaces the contaminated air towards the air discharge openings. Natural...
