SUPPLY AIR VALVE VELCO 125 PREMIUM

Velco 125 PREMIUM is a wall-mounted, automatically outdoor temperature-regulated supply air vent solution with an extremely effective three-part sound attenuation system. The 125 mm diameter of the vent enables effective sound attenuation without compromising air filtration or airflow characteristics.

The reliable bimetallic thermostat of the supply air vent adjusts its opening according to outdoor temperature between +10°C and -5°C, preventing drafts and improving the energy efficiency of ventilation. The vent is suitable for applications with either gravity or mechanical exhaust ventilation.

Features

• Includes a novel three-part sound attenuation system (including sound attenuation pipe, louver attenuator, and attenuated wind guard), which effectively reduces incoming noise and enhances residential comfort.
• The vent’s sound attenuation rating is Dn,e,w 41 dB according to SFS-EN ISO 717-1.
• The vent automatically adjusts according to outdoor temperature. A bimetallic thermostat based on thermal expansion regulates the vent flap opening between +10°C and -5°C. At temperatures colder than this, a minimum opening of just a few millimeters ensures sufficient and draft-free ventilation. The minimum opening can be adjusted according to installation conditions. The vent can also be manually closed if needed.
• The unique efficiency of the filter made from 3M Filtrete™ material is based on an electrostatic charge applied to its fibers. The electrostatically charged filter attracts and firmly traps microscopic particles like a magnet, capturing 100% of pollen and significantly reducing exposure to health-hazardous fine particles according to VTT research.
• The telescopic pipes included in the package (length 150 mm) partially overlap and can be easily shortened if needed.
• The wind guard design prevents rainwater from causing moisture stress on the exterior wall and inhibits the formation of water stains.
• The product comes with a 10-year vent warranty.
