Abstract

A system which enables removal of phosphor from a CRT front panel flange. The system includes an air operated valve connected between a water supply and a nozzle. The air operated valve may be incrementally opened and closed, which enables a continuous stream of water to be discharged from the nozzle onto the phosphor to remove the phosphor. In addition, the system includes an air supply and a pair of speed controllers which control the rate at which the air operated valve opens and closes.
