Coalescing every micron of oil mist – safeguarding your every cubic meter of clean air.

1. Product Overview

The 1615943600HWS and 2911011701HWS are high-performance oil–gas separation filter 

elements designed for air compressor systems. Engineered with advanced anti-corrosion 

microfiber coalescing media, these elements effectively remove both solid particulates and

 oil aerosols from compressed air, delivering exceptionally pure, oil-free output to protect

 downstream equipment and processes.

2. Filtration Principle & Working Mechanism

Compressed air discharged from the compressor carries oil in two forms:

· Large oil droplets – easily separated by gravity and impingement within the separator.

· Fine oil aerosols (suspended oil particles) – require high-efficiency filtration through the

 micron-grade glass fiber layer.

Our filter elements utilize state-of-the-art microfiber coalescing material, which performs

 dual functions:

1. Solid particle filtration – completely removes all solid particles larger than 3μm from the

 compressed air stream.

2. Oil aerosol coalescing – captures ultrafine oil/water aerosols as small as 0.01–1μm, which 

dissolve and pass through the media. These micro-droplets are coalesced into larger oil droplets, 

which accumulate at the bottom of the filter element.

The collected oil is then siphoned back to the compressor's lubrication system through a return

 line connected to the concave bottom of the filter element. This continuous recycling process 

ensures:

· Minimal oil carryover in the discharged air

· Extended lubricant life

· Clean, oil-free compressed air for sensitive applications
