The Precision Filter Element P-187-25 is a high-performance compressed air filter element designed for precision filtration in pneumatic systems. Engineered as a direct replacement for Parker and Pneumatech series precision filters, this element effectively removes oil mist, water vapor, solid particulates, and odor impurities from compressed air streams.
Manufactured with premium glass fiber media and configured in a pleated/folded design, the C-280-35 delivers exceptional coalescing and adsorption performance. The element features a stainless steel skeleton for structural integrity, advanced “matrix mixed fiber” media for enhanced filtration efficiency, and anti-oil/acid chemical-resistant closed-cell foam sleeves to prevent re-entrainment of coalesced liquids.

Huahang Filter is a globally recognized manufacturer and supplier of high-performance filtration solutions. Unlike distributors who simply resell stock products, Huahang is a true manufacturing powerhouse with full control over design, material selection, production, and quality assurance. Our mission is to deliver precision-engineered filtration products at factory-direct prices.
20+ Years of Industry Expertise: We’ve spent over two decades specializing in hydraulic and industrial filtration. Our engineering team averages 20 years of experience, understanding the critical requirements of precision filtration across diverse applications.
True Manufacturer with Full Process Control – Huahang controls media sourcing, assembly, and final testing in‑house, eliminating the variability that comes with third‑party supply chains. This vertical integration ensures consistent product quality, full material traceability, and the ability to customize critical parameters without depending on external suppliers.
Built to Last, Priced for Reality: Through vertical integration and lean manufacturing, we deliver filters that meet premium quality standards at prices that make sense for industrial budgets. We use premium glass fiber media and heavy-gauge steel components because cutting corners on filtration always costs more in the long run.
Factory‑Direct Support: Customers receive direct manufacturer support from Huahang‘s engineering team, not through intermediaries. This means faster cross‑reference verification, quicker responses, and access to first‑hand product data for specification and troubleshooting purposes.
Quality Assurance: ISO 9001 certified manufacturing processes ensure consistent, reliable performance across all products.
The C-280-35 Precision Filter Element is suitable for a wide range of compressed air and industrial gas applications where removal of oil mist, water aerosols, and fine particulate contamination is required. It is typically installed as a final polishing filter or as part of a multi-stage filtration cascade:
Petrochemical: Instrument air systems, pneumatic controls, process air purification
Power Generation: Turbine control air, pneumatic instrumentation, boiler soot blower systems
Steel & Metallurgy: Pneumatic conveying, furnace controls, roll cooling systems
Automotive Painting: Paint spray booth air supply, surface preparation, coating applications
Shipbuilding: Marine pneumatic systems, deck machinery controls
Pharmaceutical & Food: Cleanroom air supply, sterile processing, packaging equipment
Textile Manufacturing: Pneumatic looms, air-jet weaving, material handling
General Industrial: Pneumatic tools, cylinder actuation, valve controls, blow-off applications
Q: Is this a genuine OEM filter?
A: This is a high-performance direct replacement element manufactured by Huahang Filter. It is engineered to provide equivalent fit, filtration efficiency, and performance to the original P-187-25 part. The part number is for reference and identification purposes only.
Q: What is the difference between C-series and P-series filter elements?
A: C-series (coalescing) filters are designed to coalesce and remove extremely fine oil mist, water aerosols, and sub-micron particles down to 0.01μm. P-series (particulate) filters remove solid particulates down to 1μm. C-series provides higher filtration precision for critical applications.
Q: What is the micron rating of this precision element?
A: The exact micron rating depends on the original OEM specification. Typical precision elements in this series range from 1 to 10 microns absolute or nominal. For specific technical data, please consult the manufacturer’s datasheet or contact our support team.
Q: What industries commonly use the P-187-25 filter element?
A: The P-187-25 precision filter is widely used in petrochemical, power generation, steel, automotive painting, shipbuilding, pharmaceutical, textile, and general industrial compressed air systems.
