The most suitable plastic for your application
Thermoplastic – fibre-reinforced plastic – plastic-coated steel
Selecting the most suitable material is crucial for the lifetime and operational safety of a fan – particularly where aggressive or corrosive gases are involved. As specialists in plastic fans, HLU has built a broad material portfolio based on decades of experience.
The fans are manufactured from thermoplastics such as PEs, PPs, PE or PVC – depending on chemical and thermal loads.
For particularly demanding applications, we also manufacture housings and impellers from fibreglass reinforced plastic (FRP). We also use carbon fibre (CFRP) impellers, as well as coated steel impellers, which we can provide with chemically resistant coatings if required.
FRP and CFRP housings and impellers are manufactured at our own plant in Germany. In-house production ensures the highest quality and flexibility in implementing individual customer requirements.
