IRIS (Inline Rotary Separator)separates liquids from a gas stream

Biphase: separates gas and oil (a larger, powered IRIS)

Triphase: separates gas and water from oil

The IRIS separatorThe IRIS separator


IRIS benefitsIRIS benefitsSeparation efficiency

>99% of particles over 5 microns

equal to cartridge filters

Compact, in line design

High liquid capacity

4% liquid to gas volume ratio

up to 30% by mass

Self powered
