How Do You Install An Inline Duct Fan?
Technicians install inline duct fans near the end of a long stretch of duct. The increased airflow from the inline fan helps the air-conditioning system’s blower motor push air into distant rooms. Usually an inline duct fan’s power cord plugs into a metering device mounted on the duct. When the metering device detects a demand, it turns on the duct fan. An inline duct fan and its metering device receive power from a 120-volt electric source, usually a receptacle located in the attic. Determine the installation areas for the inline duct fan and the metering device. Place the duct fan 8 to 12 feet from the end of the duct run, and place the metering device 2 to 6 feet from the end of the duct run. Choose a location that provides adequate access for maintenance and cleaning. Cut the duct for the inline fan, using the manufacturer-supplied template as a guide. If installing the inline fan in flex duct, slice the duct’s liner with a knife and cut the inner liner’s support wire with wire cut
