The reversible impeller made of glass-fiber reinforced plastic (GFRP) is designed for variable-speed Electric Fans with frequency converters and enables both supply and exhaust ventilation by changing the direction of rotation. It is intended for non-Ex applications and offers high flexibility for changing operational requirements.

The aluminum impeller can be used in almost all fan models but is not intended for explosion-protected units. It is suitable for standard ventilation tasks in areas without Ex requirements.

The GFRP impellers with sickle blade profile are designed for use in all TYPHOON fans – except Ex models. They combine reduced noise emission with high airflow performance and improved aerodynamic characteristics. Depending on the fan type and application requirements, various customer-specific versions are available.

The impeller made of glass-fiber reinforced polyamide (PACAS) is specifically designed for use in explosion-protected TYPHOON Fans. It meets the requirements for Ex applications and is used exclusively for this device category.
