Helios Fans VARD 560/6 Ex

The Helios VARD 560/6 Ex is a high-pressure in-line mixed-flow fan designed for safe and efficient ventilation in hazardous or explosive environments. Certified to ATEX standards, this model features a cylindrical housing made from pre-galvanised sheet steel, equipped with rolled flanges at both ends. The casing dimensions and mounting holes conform to DIN 24155, ensuring secure and standardized installation. Internal guide vanes further enhance airflow performance and pressure control.

The mixed-flow impeller includes eight spatially curved blades fabricated from galvanized steel, dynamically balanced to class G 6.3 according to VDI 20060 and DIN ISO 1940, offering smooth, low-vibration operation. Powered by a fully enclosed, maintenance-free 3‑phase squirrel cage motor, the unit features sealed-for-life ball bearings for quiet and durable performance. This fan is not designed for speed regulation, making it a reliable solution for fixed-speed applications in explosion-prone industrial zones.
