I purchased a replacement 5HP motor for my compressor. Dan could not have been nicer or more helpful. I will gladly be buying from this company again in the future!
Your website was easy to find what I needed and the ordering
process went smoothly.

Regular price
$792.00
Made in USA
Tsunami 1/2" Water Separator, Oil Coalescing Filter & Regulator Combo Package #4 21999-0253
Tsunami Filtration Package #4 is a complete point-of-use air station: a 50 Series water separator removes bulk water and particulate down to 10 micron, a 50 Series oil coalescing filter strips oil aerosols to .001 ppm and fine particulate to .01 micron, and a regulator with gauge sets exact working pressure right at the drop. Rated for 50 CFM at up to 250 PSI, with automatic float drains on both filter stages.
What you get:
- Water separator + oil coalescing filter + regulator with gauge, pre-plumbed on a mounting bracket
- 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 — 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
- Reverse (right-to-left) flow available as 21999-0253-R
The right setup for spray guns and pneumatic tools that need clean air at a precise pressure. For odor- and vapor-sensitive work, step up to Package #6, which adds an activated carbon stage.
