Self Cleaning Spring Purge Nozzles

Reliable spray performance in high-solids and white-water environments

Self-Cleaning Spring Purge Nozzles are engineered for shower systems operating with suspended solids or contaminated process water. An internal spring-loaded piston automatically purges debris from the orifice during pressure drops, helping prevent plugging, maintain consistent spray patterns, and reduce unplanned maintenance.

Designed For

• Save-all showers

• Knock-off showers

• White water and high-solids process water systems

Key Benefits
