The Best In Line Dryer Vent Fan

The Fantech dryer exhaust fans have been specially designed to solve the problems caused by long duct runs on clothes dryers. According to dryer manufacturers and some local building codes, exhaust fans should be added in the dryer duct run when the length of the duct exceeds 35 feet with no bends, 30 feet with one bend or 25 feet with two bends.

Inline Duct Booster Fan

A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. Contains an DC-motor with PWM-control for a quiet and energy efficient performance. Includes an intelligent controller that features advanced programming and functions. Complete kit includes one duct fan unit, one thermal controller, one corded thermal probe, two duct clamps, installation manual, all necessary mounting hardware, and a corded AC plug adapter.

Intelligent Controller

The controller can be programmed to adjust fan speeds to respond to varying high and low temperatures, and humidity. For ventilation applications, the controller can be set to run continuously, or triggered to run at customizable speeds when given power, due to its backup memory capability. Additional features includes a countdown timer, alarm system, and eco-mode. Includes detachable 12-foot precision water-resistant probe.

Quiet and Energy Efficient Design

Unlike common duct fans that uses an AC-motor which are loud and unmanageable, this duct fan features an DC-motor that is controlled using PWM (Pulse Width Modulation). This technology enables motors to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments.

When the dryer exhaust has a long run to the vent it increases drying time as well as wear and tear on the dryer. The DryerJet has been tested on runs up to 50 feet of duct and up to four 90° bends. Testing was done by an independent lab at Florida International University. Click on picture for dimensional diagram. No wiring necessary, just plug it in! Fully Automatic Operation. Features the PS-35 Pressure Switch mounted on unit completely wired to the 10-foot line cord. Auto operation with adjustable pressure switch wired to a 10, 115 volt power cord. Ball bearing motor OUT of airstream. No lint on motor. Install next to dryer or anywhere in the line – Tested to CSA standard C22.2 113-M 1984.

Minimize drying time with Spruce’s SDB110P Dryer Boost Fan Kit. The Kit includes: Energy Star Rated RB110 Inline Fan, Mounting Bracket, Air Pressure-Sensing Switch, Probe, and Vinyl tubing. An air pressure sensing switch activates the fan when you dryer is in use. Mount the fan a minimum of 15 ft. away from the dryer to prevent wet lint from contacting the fan system. RB110: CFM @ 0″ WC is 121. CFM @ 0.2″ WC is 100.

Fresh air is a crucial component for a healthy harvest. Growing plants transpire water vapor and moisture in the grow room which can cause high humidity that can stunt your plants and destroying your crop. Our inline fan can help you to maintain a healthy grow room by efficiently move large volumes of air throughout your ventilation system. For high-powered ventilation & noise reduction, our inline booster fan runs 50% quieter than leading competitors.
