Plastic fans and components

expertise and experience since 1929

HLU is a German manufacturer and specialist in fans and ventilation components made of corrosion-resistant plastics suitable for chemically contaminated exhaust air and in potentially explosive areas.
We translate our customers’ needs into innovative solutions. For example, 3D dimension sheets and QR codes on the fan nameplates are a matter of course for us, meaning you can call up the individual data card, spare parts list, declaration of conformity and operating instructions at any time. We manufacture in our own factories in Mücke Atzenhain and Ransbach-Baumbach, and our quality controls are carried out in accordance with DIN ISO 9001 and the TÜV standard.

HLU fans are used in the following areas:

  • Chemical industry
  • Food industry
  • Electroplating industry
  • Laboratory buildings
  • Universities

In addition to fans, our exhaustive parts range contains components for all manner of requirements, such as predictive maintenance. It includes C&I systems, measurement and control, sound insulation and airtight shut-off.

Further accessories such as inspection covers, pipes, duct and shaped parts, and roof attachments complete our portfolio.

We ensure short delivery times through intelligent warehouse and logistics management.

The right plastic for your application
