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.

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.

Centrifuges

Spin liquid samples at speeds of 300-4,500 rpm to separate heavier particles from lighter ones. The digital display lets you adjust both the speed and cycle time. Set the timer for a cycle time of up to 99 minutes, and the centrifuge stops when the cycle is complete.

Centrifuges for 10-ml and 15-ml tubes include 18 rotor sleeves and 18 plugs to support short or small diameter tubes.
