Glass fiber reinforced polyester centrifugal fans, also known as corrosion-resistant centrifugal fans, are fans made from glass fiber reinforced polyester material. They are generally suitable for corrosive environments.

In gas applications, emissions of corrosive gases are present. The gases transported do not allow for the presence of sticky substances, and the dust content as well as hard particles are to be less than or equal to

150mg/m³, gas temperature ≤ 60°C, relative humidity ≤. Glass fiber reinforced plastic centrifugal fans are not suitable for high-temperature environments.
