Tamarack 12 in. x 6 in. Return Air Pathway Register

The 12 x 6 Return Air Pathway for New Construction (RAP) allows the movement of air from one room to the next, equalizing pressure in the home while dampening sound and light transmission. The RAP is designed for easy installation in existing walls. Simple Pressure Imbalances caused by closed doors encourages Mold Growth. Closed interior doors cause a pressure imbalance on your HVAC system that traps air in the hallways, closets and bathrooms, preventing the much needed, easy flow back to the handler. The system tries to compensate for this breakdown in the airflow cycle by pulling more air from already cleared areas. Unfortunately, hot, humid air leaks in from unconditioned attics and wall cavities via outlets, switches and light fixtures. Toxic Mold then grows and thrives when this moisture condenses. It is remarkable how small the pressure imbalance need be. A pressure difference as small as 2.5 Pascals can cause a problem. Amazingly, 2.5 Pascals is scientifically measured at less than one bubble found in a carbonated drink (soda), but over time this pressure imbalance builds up and overworks your HVAC system beyond its design; putting your family or building occupants’ comfort and health at serious risk. The Return Air Pathway series of products from Tamarack Technologies solves this ventilation problem by eliminating the pressure imbalance and providing a true pathway for conditioned air to circulate efficiently, thus fixing the breakdown in air circulation. Perfect for CAZ or closed appliance zones that need to be ventilated. All New Construction models include a sheetrock flange and each unit comes with a pair of white grilles.
