VN-LBT ATEX Fan | Forward Curved Centrifugal Fan for Hazardous Zones

The VN-LBT ATEX is a high-capacity explosion proof centrifugal fan engineered for hazardous areas where flammable gases or combustible dusts are present. With forward-curved blades for efficient airflow, it delivers up to 35,000 m³/h of air at pressures up to 2,680 Pa. The fan is constructed from robust steel or stainless steel (304 or 316), with an epoxy coating for enhanced corrosion resistance. It features an ATEX-certified motor (IP55) and supports both 230V single-phase and 400V three-phase power supplies. Speed can be precisely controlled via an optional frequency converter.

Designed for dependable performance in ATEX Zones 1 and 2 (gas) and 21 and 22 (dust), the VN-LBT ATEX is available in sizes ranging from 220 to 560 mm. Its durable build and flexible configuration make it ideal for demanding industrial environments. Optional accessories—such as inspection windows, protection grids, flexible connections, and anti-vibration mounts—further expand its range of applications.
