Shutter Mounted Fans

The fans have a sturdy galvanized frame and aluminum louvers to prevent heat from escaping during cold months. 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.
