Specialized Diffuser Description, Area of Application and Benefits Hygienic-Ceiling-Displacement Flow Diffuser HDQ Most production processes, especially in the food industry, have extremely high hygienic requirements in every phase of production – from the raw materials to the partial or final end product. It is absolutely necessary that air entering production spaces is sterile and dust-free. Any particles released during processing must be removed quickly from the area. Furthermore, all rooms and technical equipment must be able to be cleaned quickly and without complications. Hygienically acceptable...

Specialized Diffuser Basic Segments: Diffuser HDQ consists of stainless steel case segments with a cover of plasticcoated polystyrene plates and on the discharge side a slide-in or inserted aluminum frame covered with permeable fabric. The HDQ may have a maximum width of 2000 mm and a maximum height of 500 mm. The overall length can be selected as required, but for aerodynamic reasons should not exceed 6000 mm. For reasons of handling and fabrication, each HDQ is comprised of a combination of different sections, whose individual dimensions may not exceed the following: L = 1000 mm (by multiple...
