Helios Fans HQD 560/4

The Helios HQD 560/4 is a medium-pressure axial fan engineered for demanding industrial and commercial ducted ventilation systems. With a 560mm diameter galvanized steel cylindrical housing and flanged ends compliant with DIN 24155 Part 3, this unit ensures easy integration and secure mounting within ventilation ducts.

Driven by a direct-drive 4‑pole motor, the HQD 560/4 provides a balance of airflow performance and reduced sound levels, making it suitable for environments requiring efficient yet quieter operation. The fan’s aerodynamically optimized impeller is dynamically balanced to DIN ISO 1940 – 1 (class 6.3), minimizing vibration and promoting long service life.

Key features include sealed-for-life ball bearings, built-in thermal motor protection, and an IP54-rated enclosure, which collectively contribute to low maintenance requirements and long-term reliability in continuous operation. The unit is speed-controllable via voltage reduction, offering flexibility across various ventilation demands.

Designed for air movement in temperatures up to 60°C, the HQD 560/4 is ideal for industrial halls, machinery ventilation, and large HVAC systems, delivering dependable airflow, durability, and energy-efficient performance.

Whether used in supply or extract mode, the Helios HQD 560/4 ensures solid performance and installation ease for industrial-scale ventilation applications.
