Fantech MUAS Modular Residential Makeup Air Systems

The Fantech Makeup Air System (MUAS) is a "powered" or "fan-forced" system, which is triggered when the compensated exhaust system is energized: the motorized shut-off damper opens and the MUAS fan is powered on. The MUAS fan is automatically speed-controlled relative to the speed of the compensated exhaust system fan’s speed. In other words, as the exhaust fan’s speed is increased and decreased the MUAS fan’s speed is automatically controlled so that the makeup air flow compensates the exhaust air flow rate proportionally.

• MUAS provides the EXACT amount of air needed - no more, no less
• Particulate matter is filtered from the outdoor air before it is delivered to the home
• Since it is fan-forced, makeup air can be ducted to where it can be most suitably delivered to the home
• Cold outdoor air can be tempered with optional MUAH heater kits
• MUAS can be set up by the installer for a variety of pressure schemes: slightly negative, slightly positive, or balanced
• Complies with the International Residential Code (IRC) for kitchen makeup air requirements

Your climate zone might necessitate a heater for the delivery of makeup air into the building. The optional MUAH heater may be chosen separately, if desired.
