Helios Fans HQD 630/6

The Helios HQD 630/6 is a high-performance medium-pressure axial fan engineered for use in industrial and commercial ventilation systems. It comes with a 630mm galvanized steel cylindrical housing featuring standardized flanges (DIN 24155 Part 3), allowing for seamless duct integration.

This fan is equipped with a direct-drive 6‑pole motor, delivering lower rotational speed and quieter operation compared to 2- or 4‑pole models. It’s perfect for installations requiring low-noise, low-speed airflow while maintaining reliable performance.

The aerodynamically optimized impeller is designed to reduce turbulence and vibration, dynamically balanced to DIN ISO 1940 – 1 (class 6.3) standards. This ensures smooth, long-lasting operation even under continuous use.

Designed with IP54 motor protection, sealed-for-life ball bearings, and integrated thermal protection, the HQD 630/6 offers exceptional durability and low maintenance. The fan is speed-controllable via voltage reduction, adding flexibility to its application.

Suitable for air temperatures up to 60°C, this model excels in industrial, warehouse, HVAC, and large-scale commercial settings requiring quiet, efficient, and reliable airflow.

With its rugged build and performance-driven design, the Helios HQD 630/6 is ideal for systems where low noise, energy efficiency, and long-term reliability are priorities.
