500% More Efficient Dryer Elbow
Install the Dryer-Ell to overcome length of run issues and increase efficiency. Its longer radius
and smooth interior reduce friction. In fact, it has been proven to be 500% more airflow efficient than sectioned elbows.

Based on ASHRAE methodology, it can be measured the same as straight pipe, eliminating the run-length reduction currently required for other elbows in most building codes which is reflected in 2006 IRC Section M1502.6. Today, 2009 IRC and IMC tables show the Dryer-Ell’s equivalent length to be the same as its actual length.
