Make-Up Air System - Field Controls SWG-3 Product Manual

WHOLE HOUSE MAKE-UP AIR SYSTEM
Efforts to make your home more energy efficient prevent fresh
air from entering the home and can lead to compromised air
quality and appliance inefficiency. Weather stripping, caulk,
sealants, and moisture barriers such as Tyvek
reducing air changes and locking stale air inside. When a home
can't breathe, laundry dryers, range hood fans, bathroom fans
and heating appliances take more time to do their jobs, wasting
precious energy.
These problems can be solved with the installation of a Make-
Up Air System from Field Controls. The MAS delivers fresh air
automatically, improving indoor air quality, improving appliance
efficiency, and saving energy.

HOW THE MAS WORKS
The Make-Up Air System connects the HVAC system to the
outside to allow controlled amounts of fresh air to enter
the system when needed. The system automatically senses
pressure changes and a need for air flow and opens to
bring a precise, metered amount of fresh air into the air
handler. Here the cold air is tempered as it mixes with
warm air in the return duct. The air is then heated and
distributed through the home via the central duct system.
When the need for air is fulfilled, the system closes to
prevent further air infiltration. The system must be installed
by a qualified heating and air conditioning professional
and is adjustable for homes from 1000 to 4000 square
feet. It does not require any electricity or maintenance.
