Product Overview

Suncourt's Dryer Boosting Kits are ideal for solving residential, commercial and industrial dryer vent problems where more airflow is needed. Most dryers are designed to vent about 15 ft. of duct. They supplement the fan in your dryer to enhance its efficiency. Their in-line construction allows for easy installation as well as reduced clogging. They have a high temperature rating up to 140 Degree F/60 Degree C. The fan has thermal overload protection and features an automatic reset. The Suncourt Dryer Boosting Kits come with an accurate, reliable current sensing switch that turns the fan on and off when it senses current from the dryer. Stack effect, wind and installation can interfere with the operation of pressure switches by starting the fan unnecessarily or simply not turning the fan on when required.

Customer Questions & Answers

can I used this dryer booster with a gas dryer?

everything I have read specifically mentions electric dryers but never gas
Asked by: Allwayslearning
I beleive the Suncourt rep's answer of "no", but would like to know why not. Another fan makers rep, on this portal, claims their is no difference between gas and elec.- but the switch for that fan is a pressure sensor switch not an electrical sensor switch.

Can this be used with a gas dryer?

Asked by: JP
Absolutely no! Electrically it may work, but on suncourt's website it clearly states that the DRY04 is not approved for gas dryers. This is important because if your ignighter fails, which mine has before, you will be sending unburnt natural gas through your dryer vent. If the fan motor is not rated for gas service it could spark and ignighte it. Combine that with the spinning fan and you could be shooting flames out your dryer vent that could set your grass on fire. There are dryer boosters out there that are rated for gas dryers. The motor is usually outside the vent pipe. They also typically have a temperature sensor that won't allow the unit to start until there is hot air blowing past the booster. Check the manufacturers website to make sure the booster is rated for gas dryers before purchasing.

How does the booster fan "sense" current to the dryer?

My dryer is on the ground floor of the house and I want to install the booster fan in the vent line in the attic. How do I get the booster fan to "sense" current to the dryer? Do I have to run wiring between the dryer and the booster fan?
Asked by: munreaux
A current sensing device needs to be installed in the power feed line to the dryer. The device is provided but must be mounted in an electrical box. This device itself operates as a switch in a line providing 120VAC power to the blower.

Can lint jam up the Booster? Does it have a fire potential?

Asked by: JT
Hello, In extreme cases the fan can become clogged with lint. For most homeowners the fan would not clog though. We do recommend installing a secondary lint trap between the electric dryer and the booster fan if the installed distance is less than 15 feet. That will catch most of the lint that gets past the dryer's lint trap. Install the lint trap somewhere with easy access. We also recommend inspecting the fan once a quarter and cleaning out the fan if applicable. The fan has a thermal fuse inside the motor windings. If the fan motor overheats the fuse will open and kill the fan. The fuse would reset but if the issue persists eventually the fuse would fail completely. Thanks, Suncourt

However, I couldn't get the automatic switch to work when the dryer was turned on, so ended up installing a separate switch for the fan at the dryer. The fan is quiet and moves a lot of air. It is so powerful that it blew accumulated lint out of the duct.

Had to put it in a 4" square box and it was tight. The wiring in the unit is really small compared to # 12 or # 14 wire are was hard to terminate in the unit.

Rated 5 out of 5 by from 5 Star Review Rating provided by a verified purchaser
Date published: 2017-04-04
Rated 5 out of 5 by from Corrected excessive dryer vent run condensation problem. I have a very long dryer vent run through my attic. It would allow moisture from the dryer to condensate in the pipe, drip out the pipe seams/joints, and make my attic insulation and upstairs ceiling wet. It also would collect lint on the wet vent walls. After some research, I found that the home builder did not know the limits of my dryer's built-in fan (10 to 15 feet discharge run max, with each 90* elbow counting as 5 feet). My vent pipe has three elbows, a 10 foot vertical pipe, and about 25 feet of horizontal pipe... I have MUCH more "discharge head length" than the maximum dryer designed discharge. I purchased this booster fan and installed it in about an hour. I placed it in the attic and used the switch that was provided with the unit to activate it when the dryer is running (cycles on and off with the dryer). With this switch, the booser fan only runs when needed (and my wife doesn't have to remember to manually switch it on and off). It was immediately appearant that the unit was helping my problem... a load of cloth that took 1.5 to 2 hours to dry previously now only takes between 30 and 45 minutes. AND, you can't hear the booster fan run (I mounted it between two rafters with a piece of plywood and placed flex vent piping on either side so it wouldn't transmit noise down the dryer vent pipe). I have used it now for a couple of months and have not had any more condensation issues in the attic vent pipe. I have a mechanical and electrical background, so my installation time may not reflect yours. For that matter, I would recommend having an electrician install/inspect the wiring to ensure it is up to code. As for the supplied switch, it is a "CT" style switch that seams to work best if it is used with the white common wire on the dryer feed. I would recommend this product. I am also concidering purchasing another to install as a bathroom vent when we remodel next year... it can again be mounted in the attic and I believe it would be quieter than the current bathroom fan. Just food for thought.

Rated 5 out of 5 by from Just right for the need We are having our old vent replaced as it was very inefficient. We wanted the best possible venting so we purchased this. It seems to be well made and was easy for our installer to put in. The induction switch is perfect as the fan only runs when the dryer is running - a real plus. The instructions were also very clear. There aren't very many of these type of fans available but this one seems very good quality and we would recommend it to others with a similar need.

Rated 4 out of 5 by from Works Great Works great. I have about a 50ft run with 3 elbows. Fan comes on and goes of as needed. I mounted it horizontally in a crawlspace. Very quiet. Slight vibration can be felt when standing on floor above fan when it is running. 2 compliants. 1. No where on unit or box, or in instructions does it state cfm rating - have to trust website that it is 200 cfm. 2. Current switch does not fit in 4x4 box as shown. I had to mount it diagonally in box and therefore had to drill mounting holes into box to make it work. No big deal, but I hate incorrect instructions. Wish it came with flow/speed control.
