Helios Fans HQD 630/6 Ex

The Helios HQD 630/6 Ex is a medium-pressure axial fan designed for industrial and commercial environments where explosion protection is essential. Certified to ATEX standards, it is suitable for use in hazardous zones with flammable gases or dust.

The fan features a 630mm diameter galvanized steel cylindrical housing with DIN 24155 Part 3 flanges, ensuring compatibility with standard ducting systems. Its robust construction and explosion-proof build make it ideal for environments like chemical plants, paint shops, fuel storage, and grain handling facilities.

Equipped with a direct-drive, 6‑pole motor, the HQD 630/6 Ex provides low-speed, low-noise operation, ideal for applications demanding quieter airflow. The aerodynamically optimized impeller is precision-balanced to DIN ISO 1940 – 1 (class 6.3), minimizing vibration and ensuring consistent performance.

The motor is explosion-proof (Ex) and includes IP54 protection, sealed-for-life ball bearings, and thermal overload protection for safe, continuous operation. The fan supports speed control via voltage reduction, enabling tailored ventilation solutions even in sensitive areas.

Engineered to handle air temperatures up to 60°C, the HQD 630/6 Ex combines safety with performance for mission-critical ventilation in ATEX-rated zones.

For demanding projects that require compliance, safety, durability, and quiet performance, the Helios HQD 630/6 Ex is the ideal industrial fan solution.
