This 1,500 CFM Automatic Wall Inlet uses an energy-free counterbalance air inlet that uses static pressure created by ventilation fans to open the baffle and allow fresh air into the barn - no pulleys, chains, or power units are required. The baffle and door insulation are made of rigid CFC-free Styrofoam insulation.

The adjustable corrosion-proof counterbalance slides along a heavy stainless steel wire, and is shrouded with PVC plastic for corrosion protection. The insulated storm door has stainless steel hinges and may be opened to any angle. A mesh screen over the intake prevents birds from entering the inlet. The housing and doors on this Automatic Wall Inlet are molded of tough polyethylene plastic for long life.
