The HELI VARW 315/4 EX RADAX high-pressure duct fan is a powerful ventilation fan specifically designed for applications in explosive environments. With its cylindrical duct sleeve and flanges on both sides, it allows for easy installation and integration into existing ventilation systems. The fan is directly driven and offers high efficiency in air transport. The housing made of galvanized steel sheet ensures durability and resilience, while the built-in guide vane and the semi-axial impeller with eight spatially curved blades made of thermoplast provide optimized airflow and vibration-free operation. The fan is equipped with a maintenance-free, low-noise capacitor motor that features a closed design and durable ball bearings. The explosion-proof design according to ATEX ensures safety in critical environments.
