Automatic Fresh-Air Wall Intakes

The Schaefer Outside Wall Air Intake is modular in design and is constructed of molded white polyethylene designed to give years of trouble-free service. It is easily installed and fits between 24" stud spacings.

Here's how the intake works: As the speed of the exhaust fans change, the air intake's built-in damper will open and close automatically supplying the correct amount of air to the fans allowing proper exhaust of air out of the building. The Automatic damper has an adjustable stainless steel spring which allows for adjustment to compensate for proper building static pressure.
