How does make up air work?
Also know, how does a make up air unit work?
Simply stated, a make up air unit pulls air in to your space from outdoors and conditions it to the indoor temperature, to replace air that's pulled out by your kitchen exhaust equipment. Without it, you get back drafting, poor temperature control, negative air pressure and air quality problems.
Also, how much does make up air cost?  The automated Makeup Air System (MUAS) from Fantech includes an intake hood, shut-off damper, filter, fan, duct silencer, and optional heater; available models handle air flow up to 2,000 CFM.
Similarly, you may ask, what is the difference between outdoor air and make up air?
DIFFERENCES BETWEEN MAKE-UP AIR AND STANDARD VENTILATION Standard ventilation fans bring in the outside air “as is” without heating or tempering. With a make-up air unit, that same -10° F air can be tempered to 50° F.
Do I need make up air?
The real requirement is that makeup air must be provided if it's needed. If an exhaust fan rated over 300 cfm is installed, makeup air might be needed and a calculation will need to be done.
