Maintaining Essential Safety and Building Code Requirements
The YORK® Make-up Fresh Air Ventilation System balances a building's air, which is essential to safety and building code requirements in applications that require frequent air changes. Without proper make-up air filtration, negative pressure systems can form within a structure, which may result in costly repairs, inefficiencies and ineffectiveness in air handling systems, as well as the installation of unnecessary equipment. The MA Series assures proper air volume replacement under varying conditions.
