The Helios HQW 560/4 is a square plate axial fan designed for high efficiency and durability. It features a square mounting plate with a drawn bell mouth inlet and duct, both constructed from galvanised sheet steel and finished with a dual-layer paint coating.
The fan is equipped with a highly efficient, seven-blade profiled impeller made from impact-resistant polymer, dynamically balanced to Class G 6.3 according to VDI 2060 standards. It operates reliably across a temperature range from ‑30°C to +60°C.
Powered by a totally enclosed AC condenser motor with built-in thermal protection, the fan’s speed can be controlled through voltage reduction. The motor includes low-noise, sealed-for-life ball bearings requiring no maintenance. Additionally, the fan is reversible to suit various ventilation needs.
