Helios Fans HRFW 250/2 Ex

The Helios HRFW 250/2 Ex is an explosion-proof axial fan designed to meet ATEX standards for safe operation in hazardous environments. It features a cylindrical duct constructed from galvanized sheet steel, equipped with flanges on both ends for straightforward installation. The flange fixing holes comply with DIN 24155 specifications, and a terminal box is mounted on the exterior of the casing.

This fan is equipped with a highly efficient, 7‑blade impeller made from impact-resistant polymers, dynamically balanced to Class G 6.3 according to VDI 2060 standards. It is suitable for operating temperatures ranging from ‑30°C to +60°C.

Power is supplied by a totally enclosed single-phase condenser motor. The fan is maintenance-free and operates quietly, thanks to low-noise, sealed-for-life ball bearings. This model ensures safe, reliable ventilation in explosion-risk areas.
