The compressor supplies air to a manifold for storage. Manifold compressed air energizes a stepper (linear
motor) at 10/15 second intervals to operate one of four manifold exhaust valves. Compressed air flows from
the valve into a multi-jet head for discharge through the overlapping gas jets. The multi-jet orifice geometric
arrangement compliments the flow in the filter clean air shroud. The jet arrangement provides sealing
contact of the high energy gas jet to the flow tube bore walls. This results in inducted high air flow for
cleaning the filter.
Proper filter cleaning is critical. Reduced cleaning energy will increase the hopper air stream, the flow drag
across the filter, and increase the dusting around the main broom.
Release of filter cleaning air through the multi-jet heads into the filter clean air shroud flow tubes is from the
cyclic opening of four exhaust valves. Valve opening is sequential and from the pilot valve stepper. The
stepper is energized by the manifold compressed air supplied through a pressure piloted stepper operator
valve.
Following the discharge of the filter cleaning compressed air from the manifold, the stepper operator valve
resets. This permits the compressed air to vent from the pilot valve stepper to the atmosphere.
The stepper is reset for the next flushing cycle by gas permanently accumulated in the rod end of the stepper
piston barrel. The gas accumulator charges each time the stepper cycles.
