An improved injector system including an injector operatively connected to a source of pressurized gas and mounted to an accumulator located in close proximity to the bottom of a tank containing a fluid or other materials. The injector comprises a chamber housing and a valve disposed in the chamber housing. The chamber housing is matable to an accumulator that defines an orifice, and receives pressuzired gas from an external source. The valve engages the accumulator and selectively administers or obstructs the release of the gas into the tank as directed by an actuator contained within the chamber housing. In ambient environments that tend to fool and clog the chamber orifice or accumulator orifice, a removable orifice plate is used wherein the valve engages the orifice plate.
