DESCRIPTION
The CDB8 was designed specifically to aid the exhaust velocity of commercial capacity clothes dryers. Often times multiple clothes
dryers share a common duct or a large clothes dryer exhausts into a long duct run where maintaining the transport velocity for the
lint to remain suspended in the air stream is difficult. This causes lint build-up within the duct and dryer resulting in increased dry-
ing time, wasted energy and more frequent duct cleanings. The removal of the lint from the duct system can be a frequent and
often times expensive task. The CDB8 is designed to boost the velocity within the duct so the lint is expelled to the outdoors or
defined lint collection points. The CDB8 is designed to work on vertical and horizontal clothes dryer duct systems and can be part
of a new or retrofit installation. A unique housing design with the inlet collar and outlet collar on the same plane allows the CDB8 to
be used as a 90 degree elbow or with the addition of the IEK8 In-line Elbow Kit, can be installed in-line in a straight duct run.
Horizontal exhaust duct termination hoods and multiple control options are also available.
