90 Degree Long Turn Dryer Elbow - Overcomes Length of Run Issues and Increases Efficiency - 4"

The Dryer-Ell has a longer radius and smooth interior that reduces friction. It can be measured the same as straight pipe, eliminating the run-length reduction currently required for other elbows in most building codes.  We estimate it pays for itself in 2 years - energy wise.  UL studies show it is 500% more efficient than the standard 4" ell.

Questions and Answers
Q: What is the radius of the bend of the 90 degree long-turn ell? Has anyone used this ell inside the dryer for a rear to side vent conversion? Inquiring minds want to know. Thanks.
Asked by:  - 7/20/2014 (Submit an answer)
A: the center line of the elbow is a 10 inch radius, and I have had the question before about if it would fit or not, and have not had a chance to check or heard that it would. please add to the thread if you learn it does.

Q: Why is are the ends to large to fit regular 4" tubing?
Asked by:  - 8/4/2014 (Submit an answer)
A: In dryer exhaust ventilation, it is a requirement to keep the male-female ends of the pipe in such a way that the interior does not create a area for lint to build up on. Our long turn elbow exhibits these ends and actually was designed and mostly used in the attic or crawlspace in venting to the exterior.
Flex would fit over the male end of our elbow, but it was not originally designed to accommodate a flex connection.

Excellent Product
I find the 90 Degree Long-Turn Ell 4" to be an excellent product that doesn't restrict the airflow on my electric dryer exhaust. Actually, I had already run the exhaust using a standard 90 degree Ell near the ceiling joists but disassembled it and instead used this one. However, I find it to be ascetically ugly in appearance. The functionality is great but it's a terrible thing to look at. The fins are quite ugly in appearance. I realize that a dryer exhaust pipe is nothing but a dryer exhaust pipe and that 99.999 percent of customers couldn't care less what it looks like but I take great pains to make everything ascetically pleasing to the eye. I demanded the same from a local HVAC company during a recent install of a new furnace and air conditioning unit. I'm wondering why this Ell isn't stamped at the factory as a single piece of metal with a snap together fitting similar to straight dryer exhaust pipe. Perhaps it's not possible. I don't know. I'm not an engineer. Perhaps it would unnecessarily increase the expense of the Ell which I can certainly understand. After all, business is cutthroat and competition is competition. Nevertheless, I highly recommend this Ell to anyone who doesn't want restricted air flow, especially if the exhaust run is a long one. I didn't worry about sealing the outside fins on this Ell as I used high temperature silicone caulk on the inside seams, thus sealing it completely. I used foil duct tape on all the connections of the exhaust as I didn't want any screws protruding into the pipe. I wish the major big box hardware stores and smaller hardware stores would stock this item. Again, I highly recommend this item to everyone. It's a quality piece.

90 Degree Long-Turn Ell 4"
We always order these Long-Turn Ells from The Dryerbox website. No one in our town keeps them in stock. Turn around time between ordering and receiving the parts is very reasonable. We are definitely a returning customer. I'd recommend them to anyone.

90 degree long-term Ell - 4"
Great product. It should be distributed through Home Depot/Lowes. I had a 32' run so making two turns was critical. Most importantly the turns were slow and gradual. Awesome product!!!!!!

90 degree long turn
Arrived quickly - constructed of heavy gauge materials - assembly easy but did not give confidence that it would stay assembled. Installed self tapping screws in the flanges to ensure the pieces would remain assembled. Would buy it again to get the reduction in resistance required.

90 degree long turn ELLs helped shorten drying time
My builder vented my dryer out the back of the house. The cheap aluminum foil hose was about 60 feet long. It was impossible to clean it out and I always feared a fire. So, I re-routed my vent system using 4" stainless steel pipe, two 90 degree long turn ELLs, and a Dryer Wall Vent - a total of 18 feet long. My drying time for heavy clothers was typically 60-70 minutes. Today it is 40-50 minutes with my new system which I attribute to less friction. There is also little or no lint build-up in the vent system because of the smooth interior.

Made a huge difference
I recently remodeled my laundry room and stacked my washer/dryer. That required moving the driver vent and so I also replaced the ~20yr old venting in place. I have a 25' run down to the crawl and out. Previously it had a 90degree and 2 other kinks. Now it has the 90degree long-turn ell and a straight run. The difference is amazing. The dryer is done so quick we think it must not have finished, but everything is dry. We used to have to run it twice for towels and blankets and now even stuff balled up in a sheet is dry. highly recommend
