The Helios HV 200/4 R is a flush-mounted wall fan designed for installation in walls, funnels, and thin panels, ideal for ventilation in mid-sized to large rooms through openings with a nominal size of 150 mm. The fan’s casing and facia are made from high-quality, impact-resistant white polymer. The facia features upward-directed fins covering the intake opening and can be easily removed for cleaning in soapy water.
Equipped with a high-pressure, profiled 7‑blade impeller made from durable impact-resistant polymers, this fan supports high air volume applications efficiently.
The fan is powered by a totally enclosed AC condenser motor with built-in thermal protection. It offers speed control through voltage reduction and is maintenance-free, featuring low-noise sealed-for-life ball bearings. The motor is reversible, allowing for both supply and extraction ventilation needs.
