Super Vacuum 16" x 20 ft. conductive hazard location ducting with adapter and carry bag
Hazardous Location Duct is specialized to conduct static charges away from the airflow. Static buildup could create a spark that would compromise safety in explosive environments.
Super Vacuum Haz Lo spiral ducting Spec. sheet
This duct comes with a built-in, easy to carry bag and can be attached to other duct as an extension by simply tightening the belted cuff. This quick and easy process doubles the length of the duct without use of adapters that take up space, get lost, and take up time to install.
The duct consists of graphite fibers that conduct any charge that could build-up as a result of the airflow. Airflow through the standard duct builds up static charges much in the same way as walking across carpet does.
The special clip on the end of the duct must be connected to a grounding post that carries the charge back to earth ground – usually this is accomplished through the ground plug of the electric motor.
