Engineered for direct replacement compatibility with leading original equipment manufacturers, delivering equivalent performance, minimal pressure drop, and extended operational lifespans.
In modern industrial manufacturing environments, compressed air is often called the "fourth utility." From precision electronics to heavy assembly lines, the performance of rotary screw and centrifugal air compressors dictates production continuity. At the heart of this reliability lies the air filter element. Selecting high-grade filter media ensures that particulate contaminants are captured prior to entering the compression chamber, preserving rotor tolerances and preventing oil degradation.
As a leading China air filter element manufacturer, Shanghai Jiongcheng Industrial Co., Ltd. (JCTECH) is positioned to address these demands. Operating advanced manufacturing hubs in Xinxiang, Henan province, JCTECH integrates raw material selection, state-of-the-art pleating processes, and ISO 12500 testing protocols to deliver aftermarket solutions that meet or exceed original specifications.
We deliver more than filtration media. Our engineering focus and strict QA practices provide reliable system protection and peace of mind.
Exceptional post-sale service ensures your technical staff have the tools and manuals needed for trouble-free installation and operation.
Our application engineers provide layout consultations and fluid compatibility reports for varied working environments.
We back our products with replacement guarantees that protect against defects in materials or structural design.
We incorporate client input into our manufacturing updates, continually refining our structural designs and media choice.
Shanghai Jiongcheng Industrial Co., Ltd. (JCTECH) is an established industrial filtration manufacturer with three specialized production facilities. Our core capabilities cover traditional air filter elements, oil filters, and high-performance air-oil separators. Beyond mechanical media, JCTECH formulates and blends high-end synthetic air compressor lubricants to supply industrial networks globally.
By integrating filter production with lubricant research, we help clients optimize the performance of their air compression systems. Our approach focuses on lowering system resistance, reducing fluid carryover, and extending maintenance intervals.
A quality filter element relies on a balance between flow resistance and particle capture efficiency. As industrial equipment moves toward higher pressures and stricter energy limits, our production lines adapt to support these shifts.
We use borosilicate microglass fiber webs with multi-layered structures. This design achieves 99.98% efficiency at 0.1-micron ratings. The matrix traps fine particulates, preventing them from mixing with compressor oil, which protects the rotor surfaces from wear.
Operating in high-pressure systems requires reliable mechanical strength. JCTECH uses galvanized carbon steel or stainless-steel cages, engineered to resist structural collapse during sudden pressure changes (up to 5 bar differential pressure limits).
Filtration technology is moving toward smart, low-maintenance designs. Our R&D works on:
High-performance replacements designed to match Atlas Copco compressor platforms. Built with quality media to support system longevity.
Compressors must operate in diverse settings—from coastal regions with high salt humidity to mining sites exposed to heavy dust. Standard filtration can struggle under these varied conditions. JCTECH develops solutions targeted to specific operating environments:
Features dual-stage air intake elements with pre-cyclonic separators to capture coarse dust, preventing early clogging of the primary microglass media.
Uses water-repellent synthetic fibers that resist structural softening in humid environments, maintaining integrity over long periods.
Advanced separation elements limit oil carryover to less than 2mg/m³, keeping process air clean and reducing top-up oil needs.
Our replacement filter elements and oil separators are built to replace equivalent parts across major OEM compressor brands, including:
Selected products built for demanding operating environments, featuring robust pressure resistance and high separation efficiency.
Designed for high-pressure installations. Engineered to maintain separation integrity under demanding loads.

Answers to common engineering questions regarding the selection and maintenance of compressor filter elements.
Premature pressure drop is usually caused by high intake dust concentration, humidity, or oily vapors. Elevated ambient moisture can cause dust on the filter media to swell, restricting airflow. Selecting water-repellent media or adding a pre-filter can help mitigate this.
Our separators use a multi-stage coalescing design. As oil aerosols pass through the microglass media, they coalesce into larger droplets that collect at the bottom of the element and return to the system, keeping remaining oil carryover below 2mg/m³.
Yes. Our elements use materials compatible with common synthetic lubricants, including polyalphaolefins (PAO) and polyglycols, preventing degradation of the adhesives or media.
Most elements are designed for 2,000 to 4,000 hours of operation. However, dusty or hot environments may require shorter intervals to maintain optimum pressure.
JCTECH aftermarket filters are built to meet the same dimensions, efficiency ratings, and pressure specifications as the OEM parts, offering equivalent system protection.
