The AirCycler® g2 System is the industry’s most efficient and economical solution for meeting all whole house mechanical ventilation standards. By maximizing the efficiency of central furnace fan integrated ventilation - using a home’s regular heating and cooling cycles to provide supply ventilation - and exhaust fan ventilation, the AirCycler® g2 System delivers fresh air throughout the home with precise control and energy savings.

PRODUCT DETAILS


WHAT IS IT?

The complete AirCycler® g2 Whole House Mechanical Ventilation System includes the AirCycler® g2 Furnace Fan Timer, FanConnect™ Bath/Fan Light Switch with remote fan control, and a motorized fresh air damper (available in four sizes). This system provides both whole house supply and exhaust ventilation.

HOW DOES IT WORK?
AirCycler g2 Setup Options
During installation, ventilation requirements are set by entering the measured airflow and airflow required by code (Calculated Flow Setup), or by entering the desired amount of ventilation per hour (Calculated Time Setup).

The AirCycler® g2 Furnace Fan Timer is integrated with the home’s central furnace fan so that any time the central fan is turned on by the thermostat to provide heating or cooling, the AirCycler® g2 opens the motorized damper to let in a measured amount of fresh air. The fresh air is then distributed uniformly throughout the home through the existing ductwork. When ventilation requirements are met, the damper is closed to prevent over-ventilation.

By running the ventilation system at the same time as the home’s regular heating and cooling cycles, the AirCycler® g2 System saves on additional utility costs.

WHAT MAKES THE AIRCYCLER® G2 DIFFERENT?

Through a patented algorithm the AirCycler® g2 logs the ventilation time elapsed during heating or cooling cycles and compares it with the total ventilation requirements set during installation. 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) via the 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.

With basic exhaust-only ventilation solutions, stale air is being exhausted out but there is no known source of where the new, fresh air is being pulled into the home. With the AirCycler® g2, the motorized fresh air damper is opened any time the exhaust fan is on, providing a known, healthy source of fresh air.

Balanced Ventilation When used with the FanConnect™ and an exhaust fan, setting the AirCycler® g2 to Slave Mode will give you balanced whole house ventilation.
