Šifra: 7970403*LLG

Proizvođač: LLG

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
