Centrifugal ATEX Roof Fan with Vertical Outlet

The VN-Roof CV ATEX is a high-performance explosion proof roof fan engineered for safe air extraction in ATEX Zone 1 and 2 (Gas) and Zone 21 and 22 (Dust). Designed for industrial environments where explosive atmospheres may be present, it delivers robust airflow and durable performance under demanding conditions.

Capable of moving up to 20,000 m³/h of air with a static pressure of up to 750 Pa, the VN-Roof CV ATEX is built with a galvanized steel impeller and a rugged steel casing, finished with a plastic or aluminum cover for added corrosion resistance. It is equipped with an ATEX-certified IP55 motor, compatible with both 230V single-phase and 400V three-phase power supplies, and supports frequency converter control for precise speed regulation.

The fan is available in sizes from 250 mm to 800 mm and features a vertical outlet, optimized for efficient extraction from hazardous areas. Optional accessories include protection grids, silencers, dampers, switches, terminal boxes, and a roof mounting kit. Motors with alternative voltages, frequencies, or additional certifications are available on request.
