W3 Smart xs

A small giant among ventilation units
W3 Smart xs is the lowest ventilation unit on the market and the quietest for its size. The unit with modular measurements (597 x 599 x 446 mm) is the answer for home less than 150 m² (80 l/s, 288 m³/h), and can be installed above a washing tower and leaves plenty of space for e.g. a folding rack. W3 Smart xs is available also as a 740 W low energy model, whose low total output contributes to lower building costs.

A preheater as standard and smart compensation functions ensure the ventilation works continuously and does not cause unnecessary negative pressure on cold winter days. It also features the market’s smartest demand controlled humidity automation as standard.
