LT45 Dryer-Ell - Long-turn Dryer Elbow
Long-turn Dryer Duct Elbows
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.
Model LT45 delivers improved airflow efficiency for forty five degree turns. It is a straight pipe equivalent for most building code including 2009 and 2012 IMC and IRC.
Model LT45 has a four-inch diameter (the standard for dryer duct pipe) and a nine-inch overall length. It is particularly useful for installations where run length can be shortened by traversing the space diagonally (i.e.: attic or basement). Like the LT90, its smooth interior and ten inch radius affect flow rate to the same degree as straight pipe.
