MUAS Makeup air system

Powerful, vented range hoods exhaust smoke and grease from the kitchen to the outdoors, but an equal amount of supply air needs to enter the home to keep pressure levels balanced and avoid drawing air in from poorly suited places, such as chimneys, plumbing vent pipes, or even your garage.

Supplying air back into the building can be done a few different ways and can be as simple as opening a window or door. However, these methods introduce potentially freezing cold air or unfiltered air into the building. The best solution is to install a MUAS that can also reduce a home’s energy bill by providing a balanced pressure scheme.

The MUAS includes an EC-motor inline duct fan, a metal intake wall hood, a motorized shut-off damper, a filter cabinet with a pleated MERV 10 filter, a duct silencer, and 3 pairs of mounting clamps.

Each MUAS comes equipped with a Fantech Makeup Air Controller (FMAC). The FMAC provides automatic operation of the Makeup Air System. The makeup air flow rate automatically and infinitely varies proportionally with the speed at which the exhaust is operated by the homeowner. A neutral (balanced) pressure scheme is common, but the installer can also employ a slightly positive or negative pressure scheme should it be desired.
