The AirCycler® g2-k System is integrated with the home’s HVAC system. When the home’s furnace fan is turned on by the thermostat to provide heating or cooling, the AirCycler® g2 controller opens the motorized damper to let in a measured amount of fresh air. The fresh air is filtered by the return plenum filter and is then distributed uniformly throughout the home through the existing ductwork. Once the ventilation requirements are met, the damper is closed to prevent over-ventilation.

Should regular heating and cooling cycles not run long enough to meet the desired or required ventilation, the AirCycler® g2 can turn on the smaller and more economical bathroom exhaust fan (or other exhaust fan) through the optional FanConnect™ Switch. With no need to run the large central fan to provide additional ventilation, homeowner complaints of cold air or noisy operation are eliminated and efficiency is drastically improved.
