Dryer Exhaust Fan with mounted pressure switch

Dryer Booster Fan w/ Mounted Pressure Switch

Description

The DVK Dryer Booster Fan w/ Mounted Pressure Switch is designed to enhance the drying efficiency of residential and commercial clothes dryers. The dryer booster fan features a quiet and efficient backward curved impeller that is capable of overcoming long duct runs. The pre-mounted and pre-wired pressure switch simplifies the installation of the DVK booster fan.

The PST120V pressure switch in the DVK100B-PM Dryer Booster Fan Kit is an airflow proving switch. It automatically activates the dryer booster fan when it senses positive air pressure from an operating dryer. The pressure switch features an integral timer with a 10 minute ON and 15 second OFF cycle, enabling the fan to restart as long as the dryer is operating.

Helpful Tips for Dryer Booster Fan w/ Mounted Pressure Switch

Mount the DVK fan at least fifteen linear feet from the clothes dryer.
Each 90-degree elbow is equivalent to five linear feet of duct.
DVK fans are designed to vent up to 100 feet of 4-inch rigid duct.
Rigid duct is recommended to optimize the fans performance. If using flex duct, stretch it as smooth as possible. (Always consult local codes before selecting a duct type.)
For duct runs in unheated spaces, Continental Fan recommends insulated duct to reduce the effects of condensation.
An LT100 lint trap may be installed between the dryer and the booster fan to reduce lint build-up and maintenance on the fan.

DVK Fans are available in three activation methods:

Continental Fan does not recommend wiring a dryer booster fan directly into a clothes dryer. For this reason, booster fan kits are available with our recommended activation methods. If the pre-mounted pressure switch kit doesn’t suit your application, consider one of our other activation methods.
