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 in-line configuration simplifies the installation of the fan. The PST120V pressure switch in the DVK100B-PM Dryer Booster Fan Kit is pre-wired and factory mounted to the DVK100B dryer booster fan. The pressure switch 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 a Dryer Booster Fan

Most residential dryers are designed to vent approximately 15 feet of duct. With the introduction of main floor and second story laundry rooms, duct runs have become complex, often exceeding dryer manufacturers’ recommendations. The results are longer drying times, greater wear and tear on the dryer and higher energy costs.

• DVK fans should be mounted 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 fan performance.
• If using flex duct, it should be stretched as smooth as possible.
• 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.
• Continental Fan does not recommend wiring a dryer booster fan directly into a clothes dryer.
