Axial ATEX Roof Fan with Vertical Outlet

Explosion Proof Roof-Mounted Extraction Fan for Gas and Dust Zones

The VN-Roof AV ATEX is a heavy-duty explosion proof roof fan, engineered for safe ventilation in ATEX Zones 1 and 2 (Gas) and Zones 21 and 22 (Dust). Designed for extraction applications, it features a vertical outlet and axial impeller to ensure efficient airflow in hazardous industrial environments.

Available in sizes from 800 mm to 1,250 mm, the fan is powered by an ATEX-certified IP55 motor, suitable for both 230V single-phase and 400V three-phase operation. It is frequency converter compatible, allowing for precise speed control based on ventilation requirements.

The impeller is available in plastic or aluminum, while the casing can be made of steel, aluminum, or stainless steel—providing flexibility to suit different environmental and durability needs. The fan is designed for impeller-to-motor airflow, ideal for extraction from hazardous areas.

Optional components such as a roof cover with valve, silencers, shutters, and protection grids expand functionality and ease of integration. This makes the VN-Roof AV ATEX a versatile and compliant solution for safe rooftop ventilation in explosion-risk zones.
