Velco 125 PREMIUM Fresh Air Valve

Thermostat regulated Velco 125 PREMIUM is a wall-mounted fresh air valve with with effective three-part sound dampening designed for fresh air supply. A valve diameter of 125 mm enables efficient sound dampening without compromising air filtration or sufficient air flow. The thermostat adjusts its opening according to outdoor temperature enhancing ventilation energy efficiency. The thermostat fully opens at temperatures above + 10 ° C and closes it at temperatures below -5 ° C. In colder weather, a few millimeters of minimum opening ensures sufficient ventilation. The minimum opening can be adjusted to suit the installation site.

Includes a three-part sound attenuation

The efficient sound dampeningn capability of the Velco 125 PREMIUM is based on its innovative three-part sound attenuation designed to effectively dampen incoming noise. The combination is designed to effectively reduce sound with minimal pressure loss. 

Exceptional filtration efficiency

The filter effectively prevents impurities from entering indoor air. The unique efficiency of the filter, made from patented 3M Filtrete™ material, is based on the electrical charge of its fibers. According to research, it filters pollen 100% and effectively blocks a significant portion of health-hazardous small particles.

Easy to install

• Recommended installation hole diameter: Ø130 mm.

• Recommended minimum wall thickness is 300 mm.

• Telescopic inlet pipes (each 150 mm in length) partially slide into each other and can be easily shortened as needed. 

• With the included inlet pipes the maximum installation depth into the wall is about 350 mm. Additional pipes are available separately.

• Suitable as a replacement air solution for spaces with natural or mechanical exhaust ventilation.

• A high placing is recommended preferably above a radiator so the incoming air mixes with the convection flow of warm air, ensuring maximum comfort.
