Working Principles


Gradient Interception Technology

The Precision Air Filter operates on the principle of gradient interception, using multi-layer filter media with varying pore sizes. Larger particles are trapped by the outer layers of the filter, while smaller particles and oil mist are captured by inner layers with finer pores. This layered design ensures efficient filtration without excessive pressure loss, maintaining consistent air flow.


Coalescence and Adsorption Processes

For oil mist and moisture removal, the filter uses coalescence separation—oil droplets and water vapor merge into larger droplets as they pass through the filter media, then settle at the bottom of the filter housing for drainage. For odors and residual oil vapor, activated carbon adsorption (in specific filter series) traps volatile compounds, ensuring the air is not only clean but also odor-free.


Multi-Stage Filtration System

Different filter series work together to achieve comprehensive purification. Series C removes large water droplets and particles, Series T handles fine particles and oil mist, Series A targets micro oil mist, and Series H eliminates odors. This multi-stage approach ensures that compressed air meets the specific purity requirements of different applications.

Details


Particle Removal

The primary functionality of the Precision Air Filter is to remove solid particles from compressed air, including dust, rust, and metal shavings. This protects downstream equipment such as pneumatic valves, sensors, and precision instruments from abrasion and blockages.


Oil Mist and Moisture Purification

The filter effectively removes oil mist and trace moisture, preventing contamination of products and equipment. Oil mist can cause degradation of seals and lubricants, while moisture leads to corrosion—both are eliminated to ensure smooth operation.


Odor Elimination

Certain applications, such as food processing and medical equipment, require odor-free air. The activated carbon filter series (Series H) adsorbs odors and volatile organic compounds (VOCs), ensuring the compressed air is suitable for sensitive environments.


Pressure Loss Control

Despite its high filtration precision, the filter is designed to minimize pressure loss. The "gradient interception + coalescence separation" technology ensures that air flow remains consistent, avoiding disruptions to downstream processes and reducing energy consumption.

Characteristic Advantages


High Filtration Precision

The Precision Air Filter offers exceptional filtration precision, with options ranging from 3μm down to 0.01μm. This allows it to meet the strictest air purity standards, making it suitable for applications such as semiconductor manufacturing and medical device production.


Low Pressure Loss

Unlike traditional filters that sacrifice air flow for precision, this filter balances high filtration efficiency with minimal pressure loss. The optimized filter media and design ensure that compressed air flows smoothly, reducing the load on compressors and lowering operational costs.


Long Filter Element Lifespan

The filter elements are engineered for durability, with a long service life that reduces replacement frequency and maintenance costs. The robust construction resists clogging, even in high-contamination environments, ensuring consistent performance over time.


Versatile Compatibility

The compressed air filter is compatible with a wide range of compressed air systems, including those paired with air compressors, dryers, and pneumatic equipment. It can be installed upstream or downstream of dryers, adapting to different treatment system configurations.


Easy Maintenance and Replacement

The filter features a user-friendly design that simplifies maintenance. Filter elements can be replaced quickly without specialized tools, minimizing downtime. Some models also include pressure difference indicators, alerting operators when replacement is needed.


Environmentally Friendly

The filter’s efficient purification process reduces waste and environmental impact. By preventing contaminants from entering downstream equipment, it extends the lifespan of machinery, reducing the need for repairs and replacements. Additionally, the filter media is often recyclable, aligning with sustainable industrial practices.



Applications


Pneumatic Instruments and Control Systems

Pneumatic instruments, such as pressure gauges and flow meters, require clean air to maintain accuracy. The Precision Air Filter removes particles and oil mist, preventing damage to sensitive components and ensuring reliable measurement and control.


Electronics and Semiconductor Manufacturing

In electronics manufacturing, even tiny particles can cause defects in semiconductors, circuit boards, and electronic components. The high-precision filter delivers ultra-pure air, supporting processes such as PCB drilling, soldering, and component assembly.


Medical Equipment and Pharmaceutical Production

Medical equipment and pharmaceutical processes demand sterile, contaminant-free air. The filter removes bacteria, particles, and oil mist, ensuring compliance with medical industry standards and protecting product integrity.


Food and Beverage Packaging

Food and beverage packaging requires clean, dry, and odor-free air to prevent contamination and preserve product freshness. The Precision Air Filter eliminates particles, moisture, and odors, ensuring that packaged goods meet food safety regulations.


Automotive and Precision Machinery

Automotive manufacturing and precision machinery rely on pneumatic tools and equipment. The filter protects these tools from wear and corrosion caused by contaminants, extending their service life and maintaining production efficiency.



FAQ


How to choose the right filtration precision for my application?

The choice depends on your specific needs. For general pneumatic equipment, a 3μm (Series C) or 1μm (Series T) filter is sufficient. For electronics or medical applications, opt for 0.01μm (Series A) for micro oil mist removal, or Series H for odor elimination.


Where should the Precision Air Filter be installed in a compressed air system?

It is typically installed downstream of air compressors and dryers (or before dryers for pre-filtration). Installing it close to downstream equipment ensures maximum protection against contaminants.


Does the filter affect air flow or pressure?

The filter is designed to minimize pressure loss while maintaining high filtration efficiency. The "gradient interception" technology ensures that air flow remains consistent, with pressure loss kept within acceptable limits for most industrial applications.


How often should filter elements be replaced?

Filter element lifespan varies based on usage and contamination levels, but most have a service life of around 2,000 hours. Replace elements when the pressure difference reaches the manufacturer’s recommended threshold, or as indicated by a pressure difference gauge.


Can the filter remove both oil mist and moisture?

Yes, the Precision Air Filter uses coalescence separation to remove oil mist and trace moisture. For applications requiring complete moisture removal, pair it with a freezing dryer or adsorption dryer for optimal results.
