Oil–Gas Separator Elements – 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

FAQ

Q1: What is the primary function of these oil–gas separator elements?

These high-performance elements are designed for air compressor systems, 

utilizing advanced anti-corrosion microfiber coalescing media to remove both solid particulates and 

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

equipment and processes.

Q2: How do these elements separate oil from compressed air?

The elements perform dual functions – first, they completely remove all solid particles larger than 3μm;

 second, they capture and coalesce ultrafine oil/water aerosols as small as 0.01–1μm into larger droplets, 

which accumulate at the bottom and are automatically siphoned back to the compressor's lubrication 

system through a return line.

Q3: What is the difference between large oil droplets and fine oil aerosols?

Large oil droplets are easily separated by gravity and impingement within the separator,

 while fine oil aerosols are suspended oil particles that require high-efficiency filtration through the 

micron-grade glass fiber layer to achieve near oil-free discharge air quality.

Q4: How does the automatic oil return mechanism work?

The collected oil accumulates at the concave bottom of the filter element and is continuously siphoned back

 to the compressor's lubrication system through a return line – this self-draining design ensures minimal oil carryover,

 extends lubricant life, and maintains clean oil-free compressed air for sensitive applications.

Q5: What industries and applications are these elements suitable for?

These elements are ideal for rotary screw air compressors and industrial compressed air systems requiring high 

purity levels – particularly suited for applications with stringent oil-free air requirements such as food processing, 

pharmaceuticals, electronics manufacturing, and painting and coating operations.

Q6: What are the key performance advantages of these separator elements?

Key advantages include superior separation efficiency that reduces oil carryover to minimal levels, reliable 3μm 

absolute solid particle removal that protects valves and pneumatic components, low pressure drop that

 maintains energy efficiency, durable anti-corrosion construction for extended service life,

 and cost-effective operation with extended replacement intervals and reduced oil consumption.

Q7: What makes the microfiber coalescing media superior to conventional media?

The state-of-the-art anti-corrosion microfiber material offers long service life even in harsh operating conditions, 

delivers superior oil separation efficiency over conventional media, and ensures consistent performance through

 its ability to capture ultrafine aerosols while maintaining low resistance to flow.

Q8: What is the expected replacement interval for these elements?

Replacement intervals depend on operating conditions, compressed air quality, and system load – however, 

the durable construction and anti-corrosion materials ensure extended service life, and the self-draining design 

reduces oil saturation, contributing to longer element life and reduced maintenance frequency compared to 

conventional separator elements.

Q9: Can these elements be used as direct replacements for OEM separator filters?

These elements are engineered to meet or exceed OEM specifications for dimensional compatibility,

 filtration performance, and material standards – providing a reliable, cost-effective alternative that delivers

 equivalent protection and air quality while reducing procurement and maintenance costs.

Q10: What maintenance practices are recommended for optimal performance?

Regularly monitor differential pressure across the element and replace when the recommended change-out 

differential pressure is reached, ensure the return line siphon is functioning properly to prevent oil accumulation,

 inspect seals and gaskets during each change-out, and maintain proper compressor operating conditions to 

avoid excessive oil carryover or premature element loading.
