Airsystems The Original Saddle Vent®

Designed for use in Non-Hazardous Locations

The Saddle Vent® was developed by Air Systems and has been in use around the world for over 25 years to make it easier and safer for workers to enter and exit a confined space. The Saddle Vent® takes up only 3 inches in a manhole opening and functions as a fresh air conduit to the workers in the confined space. With the Saddle Vent® in place, continuous ventilation is supplied to the workers by eliminating the need to remove the 8” air duct each time a worker needs to enter or exit a confined space, increasing both safety and productivity.
