Automatically adjustable supply

air valve based on outdoor temperature

Automatically adjustable Velco supply air valves based on outdoor temperature prevent drafts and improve ventilation energy efficiency. The operation of Velco supply air valves is based on a self-sufficient thermostat that adjusts the valve opening smoothly within the range of +10°C to -5°C. In colder weather, the minimum opening is sufficient to provide demand-controlled ventilation. Thermostat-operated supply air valves do not require manual adjustment from the residents. Based on extensive domestic user experience, thermostat valves are covered by a 10-year warranty.
