Obtaining Uniform Air Inlet Openings

In a negative pressure ventilation system, exhaust fans draw fresh air into the house as well as exhaust stale air from the house. Side wall inlets help to distribute fresh air throughout the house as well as to direct the incoming cold air toward the ceiling and away from the birds. As the cold incoming fresh air moves along the ceiling it mixes with the warm air produced by birds/brooders which “dries it out” before the air moves toward the floor and over the birds.
