1625481101 Air Oil Separator Spin-On Coalescing Element For Rotary Screw Air Compressor

Product Introduction

The 1625481101 air oil separator is a spin-on coalescing element that pulls lubricating oil out of the compressed air stream in oil-injected rotary screw compressors. Fine glass-fiber media traps oil mist, lets clean air pass, and returns coalesced oil to the lube circuit. When separation efficiency drops, outlet air carries oil, consumption climbs, and differential pressure rises—so a tight, correctly seated element protects downstream dryers, filters, and tools while keeping lube oil in the machine.

Detailed Product Description

Separation Is Where Operating Cost Shows Up

After compression, the air leaving the separator tank still carries atomized oil. The element does not simply block particles; it coalesces microscopic oil droplets, grows them into films and droplets, and drains them back through the return path. The result is low residual oil at the discharge and stable pressure drop across the service interval. Once the media loads or bypasses, operators see oil mist at the aftercooler, faster oil top-ups, and higher energy draw from rising ΔP.

Key Benefits

• Low Oil Carry-Over: High-efficiency coalescing media keeps residual oil within tight compressed-air limits.
• Energy-Side Design: Low initial pressure drop reduces compressor power loss as the element ages.
• Built-In Return Path: Separated oil drains back to the sump instead of leaving with the air.
• Twist-On Service: Integrated canister suits external separator mounts for fast planned changeout.
• Also Called: air oil separator, oil gas separator, spin-on separator, coalescing separator element, lube oil separator canister.

Common Applications

• Oil-injected rotary screw air compressors with external spin-on separator housings
• GA-class and portable screw packages listed by suppliers as reference applications
• General manufacturing, workshop air systems, painting, food, and electronics support lines
• Scheduled separator service and compressor maintenance inventory
