Velco valve automatically adjusts according to the outdoor temperature

Velco fresh air inlet features a fully self-contained wax thermostat that adjusts the valve disc opening according to the outdoor temperature, within a range of +10°C to -5°C. No electricity required! In colder conditions, a minimum opening of a few millimetres ensures sufficient ventilation. If necessary, the valve can also be closed manually. By automatically adjusting to the outdoor temperature, the fresh air inlet helps prevent draughts and improves the energy efficiency of your ventilation.

Where should Velco valves be located?

The air entering through the fresh air inlets (yellow arrow) flushes the living areas as it flows toward the exhaust air valves (grey arrow) located in the kitchen, WC and washrooms, as well as walk-in closets.

The sufficient number of fresh air inlets can be proportioned to the floor area of the dwelling — one for every 20 m². It is important that the dwelling has enough fresh air inlets relative to its size, as too few will create a feeling of draught.

Proven to deliver the market’s most effective filtration

The Velco filter significantly reduces the entry of impurities into indoor air. It filters out 100% of pollen and effectively prevents the infiltration of fine particles that are highly harmful to health.

The exceptional filtration capability of Velco filters is based on an electrical charge applied to the fibers of the material. The electrically charged filter attracts even microscopic particles like a magnet and traps them within the fiber structure of the filter. The filters are made from patented 3M Filtrete™ filter material.
