Long-turn Dryer Duct ElbowsU.S. Patent 7,210,505
Dryer-Ells are ten inch radius, smooth interior elbows that reclaim allowable duct length. Based on ASHRAE methodology for calculating friction loss, they can be measured the same as straight pipe. This removes the run length penalty most code requires for every elbow.
Adopted in ICC International Mechanical and Residential Code, Dryer-Ells can be the perfect solution for length-of-run issues. The Dryer-Ell increases dryer efficiency, and--when replacing a restrictive small radius elbow--it can be used as an alternative to expensive booster fans.
