Qualitative Quartz microfibre filters, QFH, round filters

Recommended filters for atmospheric pollution control and for particles determination at high temperatures.
  • Filters made of pure quartz microfibre (SiO2), free of binding elements or additives
  • Extremely low content in alkali-earth metals
  • Determination of suspended particles (SPM and TSP) in ambient air acc. to the directive of the US EPA (Environmental Protection Agency) and the EN 23210
  • Retention: Excellent retention of very fine particles through the adsorption mechanisms of quartz fibres
  • Chemical stability: excellent stability with hardly any loss of filter-material due to chemical reactions under extreme conditions with acid gases (HCl, SO2, SO3, H2SO4, NO and NO3)
  • Resistance to chemical reagents: excellent resistance to solvents, acids (except HF) and alkaline substances
  • Stability at high temperatures: higher resistance than glass microfiber, up to 1000 °C
  • Weight: 85 g/m2
  • Thickness: 0.45 mm
