American Coolair’s new FGXM54 Damper Door fans are designed to be mounted over a wall opening from 56.5 inches to 58 inches square. The fans can be installed as part of new construction or to replace existing fans. The fan panel is constructed of reinforced fiberglass and is coated with a U.V. gel coat for long life. Epoxy coated galvanized structural uprights securely hold the motor and blade assembly.
When powered up, the fan’s damper doors open fully maximizing airflow by reducing blockage. The doors close and seal magnetically when the power is turned off. The FGXM54 has a gasket around the circumference of the doors to give it a complete weather barrier.
With Coolair’s cast aluminum and aerodynamic airfoil blades, the FGXM Damper Door fans are engineered to maximize performance. Cones and damper doors made with high-density polyethylene plastic for durability, and all galvanized parts are epoxy coated.
