As a leading manufacturer with over 25 years of experience in filtration solutions, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Oil-Gas Separation Filter Element for Compressed Air Systems. Designed to deliver 0.5μm filtration efficiency at 150psi, this element effectively removes oil aerosols and particulate contaminants from compressed air, ensuring clean, dry air for downstream equipment. Our factory, established in 1998, exports to global markets including North America, Europe, and Southeast Asia, with annual export value exceeding US$5 million – a testament to our reliability and quality.
This filter element is engineered for industrial machinery where oil carry-over can cause equipment damage, product spoilage, or safety hazards. Using advanced coalescing technology, it separates oil from compressed air with high efficiency, reducing oil content to as low as 0.01 mg/m³. The robust construction withstands continuous operation under tough conditions, making it an ideal choice for pneumatic systems, spray painting, food packaging, and more.
Key Features & Benefits
- High Filtration Efficiency: 0.5μm absolute filtration removes 99.97% of oil aerosols and solid particles, ensuring compliance with ISO 8573-1 class 1.2.1 (or better).
- Durable Construction: Multi-layer borosilicate glass fiber media bonded with epoxy, supported by stainless steel inner and outer sleeves, resists corrosion and pressure spikes.
- Low Pressure Drop: Optimized pleat design minimizes flow resistance, saving energy and reducing compressor load.
- Wide Compatibility: Fits standard filter housings from brands like Sullair, Atlas Copco, Ingersoll Rand, and custom sizes available upon request.
- Easy Installation: Threaded connection (1/2" NPT, 3/4" NPT, etc.) or flanged options; no special tools required.
- Long Service Life: Up to 8000 hours of operation under normal conditions, depending on inlet oil load and maintenance.

Our filter elements are manufactured under strict quality control, with each unit tested for burst pressure, filtration efficiency, and flow capacity. The 0.5μm rating ensures that even sub-micron oil droplets are coalesced and drained, preventing lubricant contamination in pneumatic tools, valves, and cylinders.
Why Choose Our Filter Element?
Compared to standard particulate filters, our oil-gas separation element offers superior coalescing performance. The special gradient density media captures oil aerosols while allowing water vapor to pass through, reducing the load on downstream dryers. Customers report up to 30% reduction in maintenance costs due to extended equipment life and reduced oil disposal.
We serve a wide range of industries: automotive, pharmaceutical, food & beverage, chemical, and general manufacturing. Our filter elements are compatible with both rotary screw and reciprocating compressors, providing reliable protection for sensitive applications like pneumatic conveying and instrumentation.

Frequently Asked Questions
- Q: What is the difference between a particulate filter and an oil-gas separation filter? A: A particulate filter removes solid particles, while an oil-gas separation filter (coalescing filter) removes liquid oil aerosols and sub-micron droplets. Our element does both: 0.5μm absolute filtration for solids and coalescing for oil.
- Q: Can this filter element be used in high-humidity environments? A: Yes, it can handle high humidity. The coalescing media also removes water aerosols, but for bulk water removal, a water separator is recommended upstream.
- Q: What is the recommended replacement interval? A: Under normal operating conditions (oil load ≤ 5 ppm, 150 psi, 80°C), replacement is recommended every 6-12 months or when differential pressure reaches 0.7 bar (10 psi).
- Q: Do you offer custom sizes or connections? A: Yes, we can customize outer diameter, length, end cap style, and thread type. Please provide your housing specifications for a tailored solution.
- Q: Is this filter element compatible with synthetic or mineral compressor oils? A: Yes, the media is chemically resistant to both synthetic (PAO, diester) and mineral oils. Temperature range ensures compatibility.
- Q: How do I drain the separated oil? A: The filter element is designed to be used in a housing with a manual or automatic drain. The coalesced oil collects at the bottom of the housing and can be drained periodically.
- Q: What is the typical flow rate for a standard 4.5"x20" element? A: At 150 psi, the rated flow is approximately 10-15 SCFM (standard cubic feet per minute) per square foot of media area. Exact flow depends on housing design.
- Q: Can I wash and reuse the filter element? A: No, this is a disposable filter element. Washing would damage the media structure and reduce filtration efficiency. Our elements are cost-effective for single use.
