This ceiling air inlet has a patented design that maximizes air management.

This TopJet 4-Way Ceiling Air Inlet has a revolutionary, patented design that maximizes air management.

This gravity-operated inlet was designed to provide birds with a better mix of air and to help growers maintain higher ventilation rates during cold weather without sacrificing house temperatures or wasting fuel. They supplement house sidewall inlets to provide an automatic supply of tempered air during the early stages of minimum ventilation without the need for a winch.

This all-season, 4-way inlet features counterbalance louvers that open from the top, instead of the bottom. It pulls warm air into the house and directs the air along the ceiling. The air current stays up longer, mixing with room air and evenly distributing fresh air while minimizing or eliminating bird stress.

Patent No 6,475,078.
