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. For International Residential Code, the Dryer-Ell™ qualifies for a run length credit under 2006 IRC Section M1502.6.
