External Mount Duct FansWhen space restrictions prevent the use of in-line duct fans, EXT External Mount Duct Fans can be used, said the company. EXT fans provide a simple through-the-wall solution, and can be sidewall mounted on the exterior of a building to allow for easy access to the fan. Installation space can be as little as 4 inches, providing room to connect appropriate duct. EXT fans utilize quiet and energy-efficient external rotor motors. They are available in standard 4-, 6-, and 8-inch duct sizes. The fans have permanently lubricated ball bearing motors. The maintenance-free motor has enclosed housing to keep out dust and lint. Features include automatic reset thermal overload protection, vibration-free operation, rugged construction for long life, speed controllable, and built-in backdraft damper.
