The new Air-In® Chameleon window supply air valve is a sophisticated Finnish supply air valve and heat recovery device. With the heat recovery, supply air is heated by up to 20°C. On sunny days from February on, the efficiency can be up to 1,000 W.
The new Air-In® Chameleon valve has properties never seen in valves before. The filter of the renewed Chameleon valve, for example, can be easily replaced without tools.
In addition to the wishes of inhabitants, ecological requirements have been observed to the extreme and free solar energy is utilised. Air-In® Chameleon improves the energy efficiency and energy classification of apartments, creating important savings in heating costs.
A new patented base part allowing the removal of the valve without tools for valve replacement, for example. The old filter is removed, a new one pressed in place and the valve simply pushed back to the base part in the window.
Additional manual adjustment of the automatic closing device allows adjusting the direction and throw of the air jet or the direction of the jet to the left or right. When the bar is adjusted upwards, the speed of the air jet decreases. When the bar is adjusted downwards, the speed of the air jet and the throw increase. The valve is closed by gently pressing the ends of the bar.
Can be equipped with a static electricity honeycomb filter lasting several times longer than traditional filters. Vacuum cleaned, replaced approximately once a year. The filter is an excellent pollen filter.
The Air-In® Chameleon valve has both summer and winter settings. The position can be easily changed using the adjustment lever. The filter housing or a thermal filter bar is installed in the window interspace.
