The Helios HQW 560/6 is a high-performance square plate axial fan designed for efficient airflow. It includes a square mounting plate with a drawn bell mouth inlet and duct, both made from galvanised sheet steel and coated with two layers of protective paint.
This model is fitted with a seven-blade, profiled impeller made from impact-resistant polymer, dynamically balanced to Class G 6.3 according to VDI 2060 standards. It operates reliably within temperature ranges from ‑30°C to +60°C.
The fan is powered by a totally enclosed AC condenser motor equipped with thermal protection contacts. Its speed can be adjusted through voltage reduction, and it features low-noise, sealed-for-life ball bearings that require no maintenance. The fan is also reversible to accommodate different ventilation requirements.
