Description 

This make up air fan is designed to supply fresh outside air for buildings requiring frequent air changes. It is necessary to have a large enough blower to prevent negative air pressure. In addition, having the proper sized make up air fan will reduce heating costs by utilizing stratified heat under the ceiling, destratify indoor air temperatures from ceiling to floor, permit exhaust systems to operate properly during the heating season, eliminate cold drafts due to the infiltration of outdoor air, prevent reverse flow through gravity vents and chimneys, improve the operation of heating equipment, and solve indoor air quality problems.
