Installing a Dryer Vent Booster Fan Hassle-Free

A dryer vent booster fan can increase the life of your dryer, increase the dryer’s efficiency, and decrease the fire hazard in your home. Follow these guidelines to install your fan quickly and hassle-free.

Choose Booster Fan
There are several models of booster fans. The most efficient and easiest to use have automatic sensors that can tell when the dryer starts and then they turn on as well. Look for a model that plugs into a regular 120 volt wall plug. Another great feature for a booster fan is a sealed motor. This means that none of the lint from the dryer will ever reach the motor and gum up the works.

Remove Old Dryer Duct
Booster fans need to be installed a distance from the dryer, usually at least six feet. Locate a spot about that far from the dryer and look for a joint in the rigid duct leading from the dryer. If your dryer uses flexible foil covered or white plastic vent, this would be an ideal time to exchange it for the much safer rigid metal ductwork.

Measure and Install Ductwork onto Fan
Booster fans generally have joints that fit directly into regular 4” dryer duct. Most can be configured any way that is necessary for your location. It may be necessary to trim a piece of duct to make it the right length for the fan.

Clamp or Seal
Either use a clamp or use metal duct tape to attach the fan. Plug it into the wall. Turn on the switch, if that model has one, and enjoy the new dryer vent booster fan.
