The Residential Make-Up Air System (RMAS) by CCB Innovations is a universal solution to meet the IRC M1503.4 make up air code requirements. Our MUA damper was designed and engineered to provide a reliable and effective solution to negative air pressure concerns resulting from the use of high CFM kitchen exhaust hoods, making it the product of choice for the home building industry.
