Make up air fans ventilate buildings for optimal indoor conditions. They eliminate the problem of negative air pressure. They also destratify indoor air temperatures from ceiling to floor. Exhaust fans are able to function more efficiently due to the controlled influx of air. Heating costs are decreased by the utilization of stratified heat under the ceiling.
