For better air mixing, Double L Wall Inlets are designed to direct airflow towards the ceiling, allowing fresh air to mix with warm air, evenly distributing tempered air throughout the room. TJW TopJet Gravity Wall Inlets have counterweighted blades that automatically open and allow fresh air to mix with warm air, evenly distributing tempered air throughout the animal room. Engineered to open at 0.05 to 0.07 static pressure, each gravity inlet blade has an adjustable counterweight for balancing multiple inlets at different static pressures.

Double L Ductwork easily adapts as a replacement for continuous baffle. Ceiling Mount Ductwork allows for two-directional air delivery from a center slot in the ceiling. The air supply is from the attic or pre-heated hallway. Corner Mount Ductwork is excellent when used to pull air out of the attic.
