for balancing kitchen exhaust up to 750 cfm, 8" duct
Item #: K46013
The MUAS is a powered, fresh air supply system that’s ideal to balance the outgoing vented air from a 400+ CFM range hood required by the IRC. This solution is designed for residential kitchen supply systems that have exhaust needs of up to 750 CFM.
• Variable supply airflow automatically in proportion to the exhaust
• Filters outdoor particles before fresh air is delivered to the home
• Flexible installation options for homeowner convenience
• Optional Makeup Air Heater (MUAH) kits to temper cold, incoming outdoor air
• Works with a variety of pressure schemes: slightly negative, slightly positive, or balanced
• Provides the exact amount of air needed
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 750 includes an 8” EC-motor fan with airflow up to 750 cfm (max), an 8” metal intake wall hood, an 8” motorized shut-off damper, an 8” filter cabinet with a pleated MERV 10 filter, an 8” duct silencer, and 3 pairs of 8” 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.
