Interlocked make-up air systems avoid wasted energy associated with barometric solutions and do not let unwanted air into the home during heating or cooling activities so air pressure is equalized for a well-balanced environment

Fresh air wall caps are required for use with make-up air dampers

See interactive make-up air specifier tool for suggested model(s)
