Sealing & Support Construction

End Caps: Integrated solid stainless steel top threaded connector with diversion grooves

Seal System: Dual built-in NBR nitrile O-rings, zero air bypass, resistant to high-temperature compressor oil and acidic condensate aging

Inner & Outer Support Cage: Single-layer perforated stainless steel mesh, lightweight anti-collapse support for small-size media

Key Product Advantages

Compact third-stage ultra-fine polishing barrier to protect downstream KA activated carbon filter and miniature precision equipment

Installed after medium coalescing filter, SI10202 captures invisible trace submicron oil mist and micro water droplets that medium filters cannot separate. It drastically reduces oil contamination load on terminal carbon cartridges, extends carbon service life and cuts spare parts cost for small pneumatic equipment.

Miniature high dirt & liquid holding capacity for limited-space installation

Deep-pleated microglass matrix stores sufficient oil and condensate within tiny dimensions. Outer green drainage foam accelerates liquid separation and gravity backflow, slowing pressure rise in small air pipelines and reducing unplanned downtime from frequent filter replacement.

Heat-stabilized glass fiber media, zero fiber shedding to avoid secondary pipeline contamination

Heat-cured borosilicate microglass composite paired with stainless steel mesh prevents glass fiber powder shedding into small-bore air piping, protecting micro spray nozzles, tiny laser optical lenses and miniature solenoid valves from clogging failure.

Low permanent differential pressure design to save small compressor power consumption

Uniform gradient pore layout minimizes airflow resistance throughout full service cycle. Stable low backpressure reduces continuous load of small screw compressors and portable air pumps, lowering long-term factory electricity expenses.
