Helios Fans KWL 200 W ET R

The Helios KWL 200 W ET R is a compact heat recovery ventilation unit designed for central air supply and extract systems in residential buildings and apartments. This right-hand configuration model is fully compatible with the Helios easyControls 3.0 system, featuring integrated network connectivity for modern control and monitoring.

Built with a powder-coated galvanized steel housing in white, the unit has a double-walled design with 12 mm of heat and sound insulation on all sides, ensuring quiet and efficient operation. Designed for quick installation and easy maintenance, all internal components are accessible via removable front panels.

The unit is fitted with high-efficiency EC fans and a plastic cross-counterflow enthalpy heat exchanger that achieves up to 90% heat recovery. Outdoor air is filtered through an ISO Coarse 75% (G4) primary filter, with an optional second-stage filter available as ISO ePM1 50% (F7) or activated carbon. On the extract air side, a matching ISO Coarse 75% (G4) filter is placed before the heat exchanger for protection.

Supporting airflow volumes up to approximately 200 m³/​h, the KWL 200 W ET R offers high-performance ventilation, intelligent control, and low-energy operation — ideal for energy-conscious residential applications requiring right-hand duct connections.
