500% More Efficient than Sectioned Elbows / Reclaims Allowable Run Length
The Dryer-Ell™ is a venting elbow with a large radius and smooth interior that reclaims allowable duct length. Based on ASHRAE methodology for
calculating friction loss, its innovative design removes the five-foot penalty required by most building codes for each
90-degree turn. Adopted in 2006 IRC under section M1502.6, it 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.
In-O-Vate Technologies commissioned a 2006 Underwriters Laboratories Fact Finding Report that showed
a 500% improvement in airflow versus the old, standard 4" radius 90-degree, five sectioned elbows. --View Elbow Comparion
An independent panel of 45 contractors acted as judges in a design contest that had 112 entries from 75
manufacturers. The Dryer-Ell™ took top honors with a Gold Award for ventilation products.
"Large radius
dryer exhaust elbow, provides for a 1-1 ratio"
When used with the Dryerbox, contractors are able to use the
entire 25 lineal feet that
most code allows for because The Dryer-ell™ does not require a reduction
in duct length.
