US - The TJP Wall Inlets from Double L Group, Ltd. are counterbalanced and gravity controlled for minimum or transition ventilation.

When static pressure is created by ventilation fans, the patented TJP Wall Inlets automatically open and evenly distribute air throughout the house. There are no cables, motors, or adjustments needed.

The TJP Wall Air Inlets are the most efficient counterweight wall inlet on the market with minimal expense. Ideal for southern climates, Double L TJP Inlets lower fuel costs and minimize bird loss. The TJP Inlet louver blades open from the top, directing air to the center peak of the house with no open ends or bottom leakage. Each inlet has an air deflector to optimize airflow and is easily adjustable. The lightweight yet very durable PVC Inlets will not corrode or rust and are rodent resistant.

The TJP Inlet counterbalance design can be made with different weights to open at different static pressures 0.55, 0.65, and 0.75. Double L TJP Inlets have a snap together design for side by side application. Light Trap options are also available.
