Engineered to deliver less than 3 PPM oil carryover under severe industrial operating conditions.
In high-pressure compressed air and mechanical ventilation systems, oil-air separation is critical to maintaining both the thermodynamic efficiency of the machine and the purity of downstream processes. The OEM Centrifugal Oil Separator utilizes a multi-phase separation mechanism combining mechanical inertia, fluid dynamics, and micro-glass fiber coalescing filtration.
When the compressed oil-air mixture enters the separator vessel, it is introduced tangentially or guided through specialized deflection vanes. This generates a high-velocity cyclone movement inside the separator body. By applying centrifugal force to the mixture, droplets with higher density (lubricant oil) are thrown outward against the inner wall of the vessel. The force acting on the particles can be mathematically calculated through:
Fc = (m * v2) / r
Where m represents the mass of the oil droplet, v is the tangential velocity, and r is the radius of the cyclone rotation. Because the density of the lubricant oil is significantly greater than that of the air, the centrifugal force effectively isolates the macro-droplets (larger than 10 microns). Once these droplets strike the vessel wall, gravity pulls them down into a sump reservoir at the bottom of the housing.
While the primary mechanical stage removes up to 90% of the bulk oil, micro-droplets and sub-micron aerosols (ranging from 0.1 to 3 microns) remain suspended in the air stream. To capture these, the air passes through specialized multi-layered coalescing filter media, typically constructed from high-grade borosilicate micro-glass fibers. This stage operates on three distinct principles:
As these micro-droplets collect on the microscopic glass fibers, they coalesce—merging into larger drops. The air flow pushes these enlarged drops toward the dry side of the filter element. They migrate downwards due to gravitational pull and accumulate in the return line region, where they are vacuumed back into the compressor's lubrication circuit through a scavenging line equipped with a check valve.

JCTECH (Shanghai Jiongcheng Industrial Co., Ltd.) has grown from a specialized filtration factory in Xinxiang, Henan province, into an international supplier of premium separation elements and compressor lubrication solutions. Today, we combine state-of-the-art winding technology with high-grade imported media to supply air compressor parts to clients in over 50 countries.
High-efficiency OEM direct-replacement filtration elements designed for major industrial compressor brands.
In modern industrial manufacturing, procurement speed, raw material supply security, and localized technical compliance are critical. JCTECH provides strategic global advantages that simplify procurement workflows and lower lifetime operational costs.
Our main manufacturing facilities are situated in Xinxiang, Henan Province—China’s largest industrial filtration cluster. This localization provides JCTECH with a robust, integrated ecosystem for raw material sourcing, heavy metal stamping, automated wrapping machinery, and highly skilled technical personnel. By leveraging these local resources, we achieve extreme cost-efficiencies and maintain large stock reserves of premium materials, including imported HV glass fiber and Ahlstrom wood pulp papers. Our secondary Shanghai operations manage complex international logistics, customization requests, and global customer support.
JCTECH operates under strict compliance with ISO 9001:2015 quality management principles. For heavy industrial sectors like oil & gas, chemicals, and energy production, we manufacture separation elements to meet or exceed OEM specifications. Each filter is pressure tested to ensure proper sealing, electrical grounding, and collapse resistance.
We supply complete customs clearance paperwork,Certificate of Origin documents, and material safety data sheets (MSDS) to minimize import complications, enabling smooth delivery through customs directly to your local facility.
Engineered for high-volume screw compressors and rotary vane pumps.
We select the appropriate filter element for you based on the working conditions on your site. The oil used in different operating environments varies significantly, requiring specialized materials. Our goal is to reduce the number and cost of air compressor maintenance cycles for our customers. We also provide a comprehensive warranty period; please consult us for specific details.

The industrial filtration landscape is rapidly evolving under pressure from environmental regulations and decarbonization targets. Modern compressed air plants prioritize maximizing efficiency while keeping maintenance down-time to a minimum.
Historically, oil separators were replaced on a fixed schedule. Today, operators use differential pressure (DP) transducers to monitor filter health. By monitoring the increase in DP over time, plants can perform predictive maintenance rather than reactive shutdowns. An optimal separator element maintains low differential pressure (usually < 0.2 bar initially), only ramping up as it approaches its service life limit of 2,000 to 4,000 operating hours.
Every 0.1 bar increase in pressure drop through a clogged separator increases the compressor’s energy consumption by approximately 1%. Selecting high-efficiency coalescing elements with optimal air-flow geometries directly helps plants reduce their carbon footprints and lower monthly energy expenditures.
Technical answers to common questions about industrial air-oil separation and maintenance.
High oil carryover is typically caused by a failed coalescer element, a clogged oil scavenge return line, or operating the compressor outside of its design pressure limits. When the scavenge line is blocked, coalesced oil cannot return to the compressor circuit, allowing it to escape into the downstream system.
A centrifugal separator relies on mechanical inertia and rotational kinetic energy to throw large liquid droplets out of the airflow, making it highly effective for heavy liquid volume streams. A coalescing filter uses microscopic glass fibers to collect and grow sub-micron aerosol particles, making it ideal for fine separation down to PPM levels.
As dry compressed air passes through the non-conductive glass fiber media at high velocities, static electricity builds up. If the separator element is not properly grounded to the vessel wall, static discharge can create sparks, which risk igniting oil vapors and causing an internal compressor fire.
Under normal operating conditions with high-grade synthetic lubricants, a premium replacement separator will last between 2,000 and 4,000 operating hours. This performance is contingent on using quality pre-filtration to prevent particulate loading on the coalescing media.
Higher operating temperatures reduce the dynamic viscosity of the lubricating oil, making it easier for fine aerosols to bypass the coalescing fiber structure. Maintaining proper compressor cooling helps keep separation efficiencies high.
