Tsunami 1" NPT 250 PSI Water Separator with Float Drain, 120 CFM 21999-0082
The Tsunami 120 Series water separator handles mainline duty: up to 120 CFM through full-flow 1" NPT ports, removing bulk water — up to one quart per minute — plus oil and particulate down to 10 micron. Velocity, gravity, and centrifugal force work in stages as air passes down the inner tube, reverses, and flows through orifice baffles and a stainless steel mesh element. The automatic float drain ejects collected liquid on its own.
Built like an industrial tool, not a throwaway:
Use it ahead of an air dryer as a pre-filter, on a shop mainline, or at high-flow equipment like sandblast cabinets and multi-user drops.
