Centrifugal fans

plastic centrifugal fans for conveying chemically aggressive exhaust air

HLU’s plastic centrifugal fans are specially designed for conveying chemically aggressive exhaust air. Their distinguishing feature is their extreme resistance to corrosion. They also generate high volume flows and pressure differences with optimum efficiency. Centrifugal fans are the efficient “all-rounders” of plastic fans. HLU offers you the perfect solutions for your needs, from standard products to individual bespoke products. For use in potentially explosive areas, all series are available in an explosion-proof version for zones 2 and 1 in accordance with ATEX.
