The HLU radial fans made of plastic are specially designed for conveying chemically aggressive exhaust air. They are characterized by the highest level of corrosion resistance. They also achieve high volume flows and pressure differences with optimum efficiency. The radial fans are considered efficient “all-rounders” among plastic fans. The HLU offers you tailor-made solutions for your needs, from standard products to individual special solutions. For use in potentially explosive areas, all series are available in explosion-proof versions in accordance with ATEX for Zones 2 and 1.
