Helios Fans HQD 560/6 Ex

The Helios HQD 560/6 Ex is a medium-pressure axial fan designed specifically for hazardous areas requiring explosion protection. Featuring a 560mm galvanized steel cylindrical housing with flanges per DIN 24155 Part 3, the fan is built for secure duct integration in industrial applications.

Equipped with a flameproof 6‑pole motor, the fan complies with ATEX standards for operation in explosive gas or dust atmospheres, ensuring safety without compromising airflow performance. The direct-drive motor runs at reduced speeds compared to 2- or 4‑pole models, providing quieter operation and longer service life.

The fan’s antistatic, aerodynamically optimized impeller is dynamically balanced to DIN ISO 1940 – 1 (class 6.3), minimizing vibration and enhancing durability. Additional features include sealed-for-life ball bearings, thermal motor protection, and an IP54-rated enclosure for protection against dust and splashing water.

Suitable for air temperatures up to 60°C, the HQD 560/6 Ex is ideal for chemical plants, paint shops, and other ATEX-classified zones that require explosion-proof ventilation solutions.

Combining safety, compliance, and efficient airflow, the Helios HQD 560/6 Ex is a trusted choice for hazardous industrial ventilation applications.
