It is also equipped with a heat exchanger. It is thanks to him that the heat is recovered from the exhaust air and transferred to the fresh air. This solution means that home heating costs can be reduced by up to 30 percent annually. And the system works regardless of the weather, because the recuperator we offer is equipped with an anti-freeze system that allows adequate ventilation even when there is very heavy frost outside the window.

In addition, the ventilation equipped with our recuperator supplies the house with very clean air. It is equipped with two-stage M5 class filters that allow to obtain air of 40 percent better quality than when using standard G3 and G4 class cartridges.
