The Saddle Vent takes up only 3 inches in a manhole and functions as an air conduit. An eight inch air hose is attached to both ends of the Saddle Vent and placed in the entry access hole, thus eliminating the need to remove the hose each time entry or egress is required. The saddle Vent’s unique air flow design does not reduce air flow to the worker. During confined space ventilation, static electricity can build up on the surface of the ventilation ducting and the standard orange polyethylene Saddle Vent. Given the right conditions of humidity, airborne dust and static build up, the static electricity can discharge and cause a spark. If this occurs while working in an explosive or potentially explosive environment, a major accident could result. Air Systems can now offer its Conductive Saddle Vent system to improve the safety of workers during confined space ventilation . The new black Saddle Vent and companion 90-degree elbow is manufactured with conductive polyethylene material. grounding lugs are mounted on each device. They are used to connect the steel grounding wires provided with our conductive conducting to the conductive saddle Vent and elbow. this makes a complete electrical circuit all the way back to the explosion-proof blower where the final grounding lug is located. The electrical blower must be connected to a grounded electrical source and thus completes the full electrical circuit. This circuit provides a path for static electricity to travel to a grounded source, thus preventing a build up on the surface of the ducting or Saddle Vent.
