The Air-in® Wall valve is a Finnish supply air valve for wall installation, efficiently reducing noise and filtering the impurities of outdoor air.
The air flow can be adjusted steplessly according to the weather conditions and needs. Alternatively, the valve can be equipped with an automatic bimetal adjuster, in which case it adjusts to the outdoor temperature on its own.
Air-In wall valves can be used in houses with mechanical or gravitational air vent systems.
The Air-In wall valve is a quality product made of galvanised, powder coated steel.
The Air-In 200 dB and Air-In 125J dB wall valves consist of the Air-In wall valve, flexible lead through pipe and an Air-In 200 outer grille / Air-In 125 outer grille.
Thanks to the flexible lead-through, noise reduction is even better than in a regular Air-In 160 dB/125 dB valve.
A Finnish supply air valve for wall installation. The valve offers the best noise insulation values and draught-free air volumes in the market.
The wall valves consist of the Air-In wall valve, a noise reduction cartridge and an Air-In 160/120/100 outer grille. The valve can also be equipped with automatic supply air adjustment, in which case it adjusts the volume of supply air automatically according to the outdoor temperature.
