  • Titanium alloy filter provides high corrosion resistance in high temperature, high dust environment
  • Unique internal structure design effectively reduces  the dead space of the sample gas
  • Filter uses a sintered alloy to filter 2μm and more dust particles and small gas resistance
  • Efficient inside and outside blowback structure design can effectively remove the dust, avoid congestion, reduce daily maintenance


Apply to continuous acquisition of exhaust gas samples after the combustion process, typically high dust and moisture content of the sample gas collection in power plant flue gas, cement production process
