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.

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

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.

The Dryer-Ell saves the day
  IRC building code allows a 35 foot maximum on dryer vents. I am at 33' 6" thanks to the Dryer-Ell. A regular 90-degree elbow would have cost me a 5-foot penalty which would have put me over. The installation was a snap, and I like the idea of having the smooth corner as this run goes up 12 feet before turning towards the outside wall. No worries about lint getting backed up in the traditional elbow. Great product with fast shipping. Thanks.

90 and 45 degree ell
  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.

Low resistance Elbow
  Very low resistance for an elbow and easy to clean but be sure to wear heavy gloves when assembling as the edges are quite sharp.

good product for the price
  Works as designed. The two halves of the pipe still have a bit of a gap between them even after screwing together. I'll have to use some duct seem sealer or the like. Only other option would be welded pipe which is really expensive.

Helped me meet code!
  This is a great product. My wife and I are currently building a new home (building it ourselves) and the laundry room is on an interior wall. Only when we started to run the dryer vent did we discover the difficulty in meeting the 35' length limit, especially after subtracting 5' for every (we had 3) 90 degree elbow. The solution: use the long turn ell to replace the 90 degree celing elbow combined with the dryer box to eliminate the elbow at dryer. The combination allowed us to reroute the vent so no additional elbows were required and straight shot out the rear gable. Great solution for tricky situation.
