Controlled air exchange is the most important link for a healthy indoor climate. The biggest problem is to maintain the balance between the inflow of fresh air and the loss of heat.

In other words: the art is to ventilate ecologically, while saving on heating costs. There is no simple solution for this - how long the optimal air exchange will last depends on the wind and weather, the position of the open window and many other factors. The REGEL-air 76 ventilation system puts an end to this problem, because it regulates the even exchange of air by itself without electricity. Two-stage wind pressure regulation guarantees pleasant air in the room when the windows are closed.
This intelligent solution keeps mold fungi out of your living space, which affect people's health. REGEL-air 76 is placed horizontally above the window or vertically next to the window and is therefore not installed in the field of vision of PVC windows. In addition, easy maintenance is ensured.
Are you rarely at home, or do you have a holiday house that you cannot ventilate regularly? Ventilation with REGEL-air 76 and the Kömmerling 76 PVC window system, edge-sealed version, is the right solution for you. REGEL-air 76 can also be retrofitted.
Our greenline principle: energy-efficient window systems, stabilizers in fresh material without the participation of lead and an intelligent recycling concept, provide an additional plus for the longevity of the profile.
