Purpose-Built for Compressor Discharge

The Micro-LOK JOS Series is specifically engineered to remove lubricating oil aerosols from compressor discharge gas streams. These air/oil separator elements capture sub-micronic oil droplets that would otherwise contaminate downstream processes, damage equipment, or be released to atmosphere—protecting your investment and ensuring regulatory compliance.

How Air Oil Separation Works

Oil-Laden Gas Enters

Compressed gas containing lubricating oil aerosols flows into the separator element from the compressor discharge.

Coalescing Action

Sub-micronic oil droplets are captured and coalesced into larger droplets as gas passes through the pleated media.

Clean Gas Exits

Clean, dry gas exits while coalesced oil drains back to the compressor sump for reuse—typically achieving 2-3 ppm or less.

Key Benefits

Reduced Oil Consumption

Efficient oil capture and return to sump significantly reduces compressor oil consumption and operating costs.

Equipment Protection

Removes oil contamination that causes fouling, corrosion, and premature wear in downstream equipment.

Environmental Compliance

Minimizes oil carryover to meet environmental regulations and reduce atmospheric emissions.

Extended Service Life

High surface area pleated design provides long element life between changeouts—typically 4,000-8,000 hours.

Common Applications

Rotary Screw Compressors

Oil-flooded rotary screw compressor discharge separation for plant air and process gas systems.

Reciprocating Compressors

Remove lube oil aerosols from reciprocating compressor discharge in gas processing facilities.

Natural Gas Compression

Pipeline and gathering system compressor stations requiring clean, dry gas output.

Plant & Instrument Air

Compressed air systems supplying pneumatic instruments and control systems.

Process Gas Systems

Chemical and petrochemical process gas requiring oil-free output for downstream reactions.

Refrigeration Compressors

Oil separation in refrigeration and HVAC compressor systems.
