This is a specialized product designed for equipment handling chemicals in the semiconductor and OLED display industries, specifically for dispensing DI water. The DI Water Spray System is engineered to prevent bacterial growth. When the spray gun is not in use, the DI water follows a parallel recirculation path, flowing back to the user's DI collection tank or drainage line. By eliminating stagnant water, the open-loop continuous recirculation path helps reduce bacterial growth.

A recirculating fitting is available for the PFA DI water spray guns with 3/8" flare connections.
