ATEX-Certified Inline Centrifugal Fan with Backward Curved Blades

The VN-Box BD ATEX is a high-capacity industrial fan designed for use in hazardous environments classified as ATEX Zone 2 (II3G). Built with a sturdy galvanized steel casing and equipped with a spark-proof, ATEX-certified motor, it provides safe and efficient ventilation in areas with flammable gases. With airflow capacities up to 32,000 m³/h and support for speed control via frequency converters, it is ideal for ventilating large spaces in industrial settings.

Designed to meet demanding ventilation needs, the fan features forward-curved blades that ensure stable and efficient airflow. It is available in sizes from 7/7 to 630, offering airflow from 750 to 32,000 m³/h and static pressure up to 550 Pa. The motor is IP55-rated and operates on 230V single-phase or 400V three-phase at 50 Hz, ensuring compatibility with a wide range of installations.

The galvanized steel housing can be upgraded with 25 mm or 50 mm double-panel insulation to reduce noise emissions. A full range of optional accessories—including protection grids, rain covers, mounting feet, flexible connections, and anti-vibration mounts—makes this fan adaptable to various project requirements.
