Moisture/Particle Separators

These separators remove 99% of moisture and particles, leaving you with nothing but clean dry air, inert gas, or steam. They have no baskets or cartridges to clean or replace. Particles fall to the bottom of the separator and are discharged through the drain trap with minimal pressure loss.

Separators with 150 psi are smaller and more efficient; a baffle separates contaminants from your media. Separators with 250 psi use centrifugal flow to remove contaminants from your media.

Vacuum-Rated Air Separators for Water Removal

Improve vacuum system efficiency and protect components from moisture—these separators remove over 90% of water from air. Typically used with vacuum pumps, they minimize vacuum pressure drop, even when the element is saturated with water. Separators have a viewing window so you can see inside to monitor water removal. Mount separator vertically for proper drainage (brackets sold separately), and install before air filters.
