HydroWhirl Poseidon® rotating tank cleaning nozzles, with flow rates from 4.45–26.3 gpm, are designed to fit through openings as small as 2 in. while maintaining slow, controlled rotation speed. While complete 360° omnidirectional coverage increases impact and cleaning efficacy, slow-spinning spray and extended spray dwell time on target surface increase impact. Fluid-driven and lubricated nozzles are constructed of FDA-approved, corrosion-resistant PTFE material.
