Helios Fans VARD 560/8 Ex

The Helios VARD 560/8 Ex is a high-pressure in-line mixed-flow fan engineered for applications in potentially explosive environments, offering reliable performance with full ATEX compliance. It features a cylindrical casing made from pre-galvanised sheet steel, with rolled flanges on both ends. The housing dimensions and flange mounting pattern meet DIN 24155 standards, ensuring easy and consistent integration into duct systems. Internal guide vanes are included to optimise airflow and efficiency.

Its mixed-flow impeller consists of eight spatially curved blades crafted from galvanized steel and is dynamically balanced to class G 6.3 per VDI 20060 and DIN ISO 1940, minimizing vibration and ensuring smooth operation. The fan is driven by a fully enclosed, maintenance-free 3‑phase squirrel cage motor, fitted with sealed-for-life ball bearings for long-lasting and quiet performance. This model is not speed-controllable and is ideal for fixed-speed installations in industrial zones where explosion protection is required.
