Precision Filter Element C-280-35

Type: Precision Filter Element
Part number: C-280-35
Filtration accuracy: 1,3,5,7,10..micron
Filter media: Customized
Package: Neutral carton package
Description:
 
The Precision Filter Element C-280-35 is a high-performance compressed air filter element designed for precision filtration in pneumatic systems. Engineered as a direct replacement for the original 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.

Note: Exact specifications may vary depending on housing configuration and operating conditions. Huahang Filter’s engineering team can verify compatibility and provide precise specifications for your specific installation.

Structural Features:
  • Cylindrical Cartridge Configuration – Easy one‑hand insertion into compatible filter housings simplifies maintenance and reduces downtime.
  • Sloan‑Cut / Slit End Cap – Characteristic end‑cap feature frequently used as an anti‑counterfeiting measure, enabling visual validation of genuine elements and ensuring proper seating inside the housing.
  • Support Core – Strong perforated metal inner core provides structural rigidity, preventing media collapse under differential pressure.
  • Integrated Sealing – Gaskets and O‑rings are included as accessories, ensuring a leak‑free seal between the filter element and housing.
  • Tool‑Free Element Replacement – The housing design requires no screw threads or tie rods, allowing quick removal and replacement of the element with simple hand tools.

 

Applications

The C-280-35 Precision Filter Element is engineered for use in a variety of industrial filtration systems where high fluid or gas purity is essential:
  • General Manufacturing – Protecting pneumatic tools, cylinders, valves, and actuators from contamination‑induced wear.
  • Automotive Industry – Paint spray booths, assembly line pneumatics, and robotic systems.
  • Pharmaceutical Manufacturing – Cleanroom compressed air systems, tablet coating, and packaging machinery, where ISO 8573 certified air quality is required.
  • Electronics and Semiconductor Fabrication – Ultra‑clean compressed air for wafer handling, printed circuit board assembly, and cleanroom environments, where even minute oil or particle contamination can cause product defects.
  • Textile Industry – Air jet looms, spinning machines, and material handling systems, where consistent compressed air quality ensures product quality and reduces machine downtime.
  • Plastics and Rubber Processing – Blow molding machines, injection molding equipment, and part ejection systems requiring reliable, contamination‑free compressed air.
  • Medical and Dental Equipment – Hospital central compressed air systems, dental tools, and respiratory devices, where oil‑free, particle‑free air is essential for patient safety.

FAQ

Q: Can I clean and reuse the element?
A: No. It is disposable elements with pleated glass fiber media. Cleaning will damage the media and destroy filtration efficiency. Always replace with a new element.

Q: What micron rating should I choose for my application?
A: Typical recommendations:
1µm / 3µm – High-precision hydraulics, servo valves, instrument air, critical process gas.
5µm – Standard industrial hydraulics, general compressed air purification, pneumatic controls.
7µm / 10µm – Lubrication circuits, pre‑filtration, less sensitive hydraulic systems.
If you are unsure, contact our engineering team with your application details for a specific recommendation.

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: How should I store spare precision filter elements?

A: Store in a cool, dry environment away from direct sunlight, extreme temperatures, and chemical fumes. Keep in original packaging until ready for installation to prevent dust, moisture, and contamination.
