Dryer-Ell 90 Degree Long-turn Elbow
Details
Dryer-Ell 90-Degree Long-turn Dryer Elbow overcomes length of run issues and increases efficiency.
The Dryer-Ell has a long radius and smooth interior that reduces friction dramatically. This elbow will save the user 4.6 feet of duct run because this elbow, according to the building code and ASHREA calculations, has friction loss equal to straight pipe. The typical 3.5" radius ell carries with it a run-length reduction penalty of 5 feet. Regarding efficiency, we estimate this ell pays for itself in 2 years. UL lab testing demonstrated this ell was 500% more efficient than the standard 4" ell.
Tip: Any sheet metal screw will work to mate the sections, but the easiest are the black Pro-Twist Pan Head Framing Sharp Point Screw #7 x 7/16″, which are common with HVAC tradesmen and are available at Home Depot.
Screws are not included.

Exactly what I was looking for. Excellent fit and finish.
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.

I wanted to love this product, but when I got to the customers home and tried to assemble it I kept hitting snags. As another writer mentioned, the tabs were poorly matched and there was a lot of air gap after assembly. I taped the gaps and screwed the flanges together for surety sake. The flanges themselves proved to be bulky to work around in tight spaces. As the other writer said, "needs more thought".

The Long-Turn Ell is sturdy and simple to install.

This is a well designed product. It is very rugged. Because of the wide sweep it reduces the resistance of you dryers exhaust run and increase drying efficiency.
Difficult to assemble, but still a good product

The 90 degree long-turn elbow was difficult to assemble (it comes in two pieces) and didn't seem to be very secure after I got it together the best I could. I taped up all the joints for added assurance and air tightness. At the end of the day, I was happy with how the final install worked out since I was able to get my dryer vented without exceeding the maximum allowed length thanks to the efficiency of the elbow. I would buy this elbow again if I couldn't afford to take the 5 foot penalty from a normal elbow.
90 degree long-term Ell - 4"
by Bill| 9/4/2014 12:00:00 am
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!!!!!!

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 and 45 degree ell
by Ben| 12/17/2013 12:00:00 am
The ells worked well to help meet code on a long run with a few bends. They were pretty easy to assemble for a novice, although they didn't include sheet metal screws. You should also plan on taping the seams shut.
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
by Bob| 3/2/2014 12:00:00 am
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.

I have installed three of these elbows in an apartment building laundry facility. They work extremely well. They are rugged and end help vent the room extremely well. easy to work with snd solid design. Highly recommend to vent dryers in any type of facility.
