Precision Gas Sampling Filters for Accurate Gas Analysis

CMI Gas Sampling Filters are precision-engineered for high-accuracy gas analysis and environmental monitoring systems.

By effectively eliminating solid particulate contamination from gas streams, these filters protect sensitive downstream analytical equipment, prevent measurement drift, and ensure representative clean gas samples.

Manufactured from high-performance sintered porous metals, CMI gas sampling filters provide excellent mechanical strength, corrosion resistance, and stable flow performance under demanding operating conditions.

Customized filter geometry, material, micron rating, and connection type can be engineered according to gas composition, flow rate, temperature, pressure, and analyzer protection requirements.

Core Advantages

Extreme Durability

Manufactured from sintered porous metals including stainless steel, titanium, Hastelloy, Inconel, Monel, and nickel for harsh gas sampling conditions.

Stable Gas Flow

Controlled pore structure and optimized porosity provide efficient particle retention while maintaining low differential pressure and stable gas flow.

Reusable Filter Media

Sintered metal media can be restored through backflushing, ultrasonic cleaning, solvent washing, or chemical treatment depending on contamination type.

Analyzer Protection

Removes particulate contamination before sensitive analytical instruments, reducing measurement drift, blockage, and maintenance downtime.

Typical Applications

  • Petrochemical processing and online industrial process control
  • Continuous Emission Monitoring Systems (CEMS) and environmental stack gas sampling
  • Laboratory testing, gas chromatography, and gas cabinet analyzer systems
  • Sampling probes, distribution panels, and analyzer protection assemblies
