EXT external mount duct fans are the perfect solution when space restrictions prevent the use of in-line duct fans. 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. EXT fans utilize quiet and energy efficient external rotor motors. EXT fans are available in three standard duct sizes: 4″, 6″ or 8″, with airflow’s ranging from 118 cfm to 470 cfm.
EXT external mount duct fans are the perfect solution for range hoods located in hard to vent spaces where an in-line duct fan cannot be used.
