The saddle vent device was developed and patented by air systems over 20 years ago as a safety tool to maintain continuous ventilation while allowing unrestricted entry and egress to a manhole or tank. Air systems has continued to improve the saddle vent by developing a fully conductive saddle vent and a ventilation method for removing static electricity from the entire ventilation system consisting of the entire length of ventilation duct all the way back to the blower and safely discharging static to a safe electrical ground. The new recommended method, the conductive saddle vent ventilation system, uses conductive ventilation ducting connected to the conductive saddle vent which is then connected to an explosion-proof blower or pneumatic. The entire system is assembled above ground in less than five minutes before installing it in the opening to the manhole or tank; it can then be tested for electrical conductivity using a standard ohm meter. Achieving an electrical resistance reading between 30k and 300k ohms will assure an electrical path is made for static electricity to safely discharge back to the blower and its grounded electrical connection. This ventilation system is the only safety industry method for safely removing static build-up during confined space entry; it provides continuous confined space ventilation, unrestricted entry and egress and the entire system can be tested prior to commencing work operations in a hazardous work area. A step-by-step set up of the entire conductive saddle vent system is pictured here in our catalog. Controlling static electricity discharge will prevent spontaneous ignition of hazardous vapors and dusts. As a work tool, the conductive saddle vent ventilation system will allow workers to concentrate on the many other hazards associated with working in a confined space while maintaining continuous ventilation.
