EXT External Mount Duct Fans

Description

EXT external mount duct fans are the perfect solution when space restrictions prevent the use of in-line duct fans. The simple through-the-wall design allows the fan to be sidewall mounted on the exterior of a building.

As for construction, a heavy gauge, galvanized steel housing with a baked epoxy finish provides a long life. The built-in backdraft damper helps to prevent air leakage. Additionally, EXT fans combine a quiet and efficient backward curved impeller with a powerful and speed controllable motor.
