Tsunami 1/2" Water Separator & Oil Coalescing Filter Package #3, 50 CFM 21999-0251

Tsunami Filtration Package #3 pre-plumbs the two filtration stages most shops need into one bracket-mounted assembly: a 50 Series water separator that removes bulk water and particulate down to 10 micron, followed by a 50 Series oil coalescing filter that strips oil aerosols to .001 ppm and fine particulate to .01 micron. Rated for 50 CFM at up to 250 PSI, with automatic float drains on both stages — install it at the point of use and it takes care of itself.

What you get:

  • 50 Series water separator + 50 Series oil coalescing filter, plumbed and mounted
  • Filter heads machined from 6061 aircraft aluminum, anodized inside and out
  • 1/2" NPT ports, 250 PSI maximum, 175°F maximum temperature
  • Automatic float drains on both stages — no manual draining
  • Rebuildable: water separator kit 21999-0227 and coalescing kit 21999-0202 (element every 6 months)
  • Made in Monticello, Minnesota by ISO 9001:2015-certified Suburban Manufacturing

Ideal for paint prep, plasma cutting, cabinet blasting, and tool protection. Need pressure control at the drop too? Step up to Package #4 with a regulator.
