Helios Fans HQD 710÷6÷6

The Helios HQD 710÷6÷6 is a medium-pressure axial fan designed for industrial and commercial ducted ventilation systems requiring adaptable and quiet airflow. Housed in a durable galvanized steel 710mm cylindrical casing with flanges compliant with DIN 24155 Part 3, it ensures reliable integration into any standard ductwork.

This model features a twin-speed, 3‑phase direct-drive motor with dual 6‑pole windings, allowing it to operate at two fixed low-speed settings. This setup is perfect for environments where sound levels must remain minimal while maintaining flexibility in ventilation performance.

The aerodynamically optimized, dynamically balanced impeller ensures smooth operation with minimal vibration, in compliance with DIN ISO 1940 – 1 (class 6.3). Built-in thermal contacts, sealed-for-life ball bearings, and IP54 protection make the fan well-suited for continuous duty in demanding conditions.

It is speed-controllable via voltage or frequency, offering excellent versatility for applications such as large warehouses, production facilities, or HVAC systems. The fan supports air movement in environments with temperatures up to 60°C, delivering robust, quiet, and dependable performance.

Whether for supply or extract ventilation, the Helios HQD 710÷6÷6 provides twin-speed flexibility, durability, and noise-reduction in one powerful, easy-to-install package.
