Fresh air ventilation is recommended by HVAC engineers and is prescribed in ASHRAE standard 62.2. In many states, fresh air ventilation is required to meet building codes for new construction or to obtain energy tax credits in existing homes. The FAS Fresh Air System from Field Controls meets these requirements by delivering fresh air automatically and efficiently. The FAS includes proven components for simple, reliable, fresh air delivery for improved indoor air quality.

It’s important to deliver fresh air in a way that maintains energy efficiency. The Field Controls Fresh Air System does just that, providing tempered, fresh air using the existing air handler and duct system. The AirCycler® Fresh Air Control operates the HVAC system blower to deliver fresh air throughout the entire home. The FAC is set by the contractor and works independently of the thermostat, providing better control and more consistent operation.

The Fresh Air Damper remains closed until instructed to open by the Fresh Air Control. It then opens to allow fresh air to be pulled into the return plenum where it is mixed with conditioned air, filtered, and distributed to the rest of the house.
