ATEX High-Pressure Centrifugal Fan with Backward Curved Blades

The VN-VPMR ATEX is a high-pressure centrifugal fan designed for safe and efficient air movement in ATEX Zone 1 & 2 (Gas) and Zone 21 & 22 (Dust) environments. Featuring backward curved blades, this fan delivers exceptional performance for clean to lightly dusty air, with airflow capacities up to 37,000 m³/h and static pressure up to 19,000 Pa—making it ideal for high-resistance duct systems and demanding industrial ventilation needs.

Built for durability, the VN-VPMR ATEX is available in epoxy-coated steel, galvanized steel, or stainless steel (304/316). The impeller, also available in steel or stainless steel, ensures reliable performance in harsh conditions. Powered by an ATEX-certified IP55 motor, it supports 230V single-phase or 400V three-phase operation and is frequency converter compatible for variable speed control.

The fan can be configured for multiple installation types, including motor-supported (Arrangement 4), reinforced motor plate (Arrangement 5), or belt-driven setups. With 16 outlet angles and a wide selection of custom accessories, it can be tailored to match complex operational requirements while ensuring ATEX compliance and energy-efficient operation.
