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

4 in. Dryer Booster Kit is rated 4.3 out of 5 by 18.
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 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.

Rated 4 out of 5 by from Booster works great BUT! The booster works well but the wiring instructions NEED HELP. I did the install myself but had to talk to a friend to figure out the best way to wire. Instructions state to use conduit to wire but I used Romax instead because of easy access to do so. Then I used a regular plug in from the booster to a recept box for easy removal to service[ a cord was not supplied to do so]. Booster works great and is quiet. Mounting brackets could be better made and enough for both ends not just one end for my model. Price for what I got was shaky for a plastic housed motor but I needed the booster to be in compliance with code restrictions so I'll live with it.

Rated 4 out of 5 by from Dryer booster kit This product made a big difference in the drying time. We have a number of bends before the air gets outside. Now the dryer is done well before the wash. Placed in the attic so it is very quiet. Little tricky making the power connection. This is why it didn't get 5 stars.

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 5 out of 5 by from Cut drying time from 3hrs plus to 40 minutes. We had a long route from the dryer to an outside wall (no alternative). Have had continuing problems with vent line clogging up. Even with clean lines, drying time was very long. Now much shorter as indicated above. As far as projects go, this installation was not bad but does involve electrical work as well as mounting the blower and re-routing the vent lines. This has to be installed in-line between the dryer and outside (not too close to the dryer.

Rated 5 out of 5 by from dryer booster kit Product is good and price efficient. Not happy that I had to have an electrician come in and wire it though. I know it is not your fault, but to spend over $900 to buy and install a fan for a dryer seems like a lot of money. We needed it though and it is done and the fan works the way it should work.

Rated 4 out of 5 by from Good product, difficult to install My house laundry room was located in the middle of the house so the dryer vent has a long ways to go to an outside wall. It goes about 45 feet and has a right angle bend in it (equivalent to another 5 ft from what I've read). Supposedly dryers are only designed for about a 10 to 15 feet vent line. So my dryer was having a very hard time drying clothes. A normal load might have to be run for 4 to 6 cycles each 75 minutes long. This was very inconvenient. I got this kit to try and fix the problem. I also straightened and shortened the connection from the dryer to the wall, and vacumed all the accumulated lint out of the dryer and line. The kit is pretty straight forward to install, but it does require you to make another trip to get electrical cord to power the unit and another piece of electrical cord to wire the automatic switch. I have not yet wired the automatic switch. I just put a plug on the end of the cord and plug it in as needed. But when I have time I will get a wiring box as well (not included) and run the extra wiring so it will be automatic. The fan is not too loud and drying times seem to have dropped to about one or two cycles max.
