Velco VSR-100N replacement air valve

Velco VSR-100 is a replacement air valve that can be installed in place of an old valve or an iron hatch, and automatically adjusts according to the outside temperature. The reliable wax thermostat of the replacement air valve adjusts its opening according to the outside temperature, preventing drafts and improving the energy efficiency of ventilation. The package contains a mounting plate that can be used to cover any marks caused by the old valve on the wall surface. Suitable for locations with gravity or mechanical exhaust ventilation. If the old feed-through channel is Ø 95-100 mm, the old valve can be removed and the VSR-100 installed directly in its place.

• VT-100 replacement air valve with thermostat
• S-100 filter and frame wires
• AN-10 mounting plate
• Installation glue
• Installation instructions

FEATURES:
• Adjusts automatically according to the outside temperature. A thermostat based on thermal expansion adjusts the opening of the valve plate between +10°C and -5°C. In colder air, a minimum opening of just a few millimeters guarantees adequate and draft-free ventilation.
• The minimum opening can be adjusted according to the installation site. Can also be closed by hand if necessary.
• The unique power of the filter made of 3M Filtrete™ material is based on the electrical charge charged to its fibers. The electrically charged filter attracts even microscopic particles like a magnet and traps them tightly in the filter fibers.
• According to VTT's research, it filters 100 percent of pollen and repels a significant part of small particles that are extremely harmful to health.
• 10-year valve warranty.
