ABSTRACT:
An exhaust control system and method are provided for use with one or more pneumatic devices so as to draw contaminated fluid from the fluid outputs of such devices and deposit such contaminated fluid in a waste collector such as a drain. The system is configured for use with any conventional pneumatic device of the type which includes a pressurized fluid input, a turbine driven by fluid from such input, and a fluid output which exhausts fluid from the turbine. Fluid is directed from the fluid output of each pneumatic device to an exhaust manifold which includes a number of inflow ports corresponding to the number of devices serviced. The inflow ports connect to a depressurization chamber, where the fluid flow pressure is lowered, and from which the fluid is drawn via a collective outflow port. The fluid is drawn from the exhaust manifold using a vacuum source and then directed to a waste collector such as a drain.
