Air Filters

Part Number: SI10422

Filter Grade: Secondary high-efficiency sub-micro coalescing filter 

Filtration Precision: Captures solid particles ≥0.01 μm, residual liquid oil mist ≤0.003 ppm

Filter Media: Multi-layer gradient HV borosilicate micro glass fiber composite + outer hydrophobic foam drainage layer

Core Function: Remove residual micro liquid oil mist, condensed free water and submicron fine dust after pre-filter; greatly reduce contamination load of downstream activated carbon filter

Standard Service Life: 4,000 working hours; shorten to 2,000 hours under heavy oil mist, high humidity and spraying conditions

Max Operating Pressure: 1.6 MPa

Operating Temperature Range: 2℃ ~ 65℃

Initial Pressure Drop: ≤0.01 MPa

Replacement Alarm Differential Pressure: ≥0.05 MPa

Net Weight: 0.14 kg

Application Scenarios

Small electronic cleanrooms, laboratory precision analytical instruments, mini laser cutting equipment, compact spray booths, small food packaging air supply, precision pneumatic testing equipment

Product Features

Outer hydrophobic foam layer automatically drains separated water and oil to avoid secondary re-entrainment, delivering outstanding gas-liquid separation efficiency. High dirt holding capacity glass fiber media stably controls residual oil below 0.003 ppm throughout service life.

Deep-pleated low-resistance design maintains low and stable pressure drop, effectively cutting long-term power consumption of air compressors.

Integrated EPDM rubber sealing ring offers excellent resistance to synthetic compressor lubricant oil, high temperature and aging, eliminating pipeline air leakage risk.

Standard top plug-in installation design for quick tool-free replacement, minimizing production downtime for maintenance.

Every cartridge passes strict factory tests including bubble point test, differential pressure test and oil removal efficiency inspection, fully compliant with high-precision air process requirements.

Product Description

SI10422 is the secondary precision coalescing filter specially designed for HIFI small compressed air purification systems, installed between pre-filter and activated carbon terminal filter.

It captures 0.01μm ultra-fine oil mist to produce ultra-clean compressed air meeting ISO 8573-1 Class 0 standard. It effectively prevents paint film pinholes, workpiece oil contamination and precision instrument corrosion, and extends the service life of downstream activated carbon filter by lowering its adsorption burden.
