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.
