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.
- Air permeability is extremely high. Enables to pass through large volumes of air.
- Excellent chemical 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).
- Excellent chemical resistance to solvents, acids (except HF) and alkaline substances.
- Stability at high temperatures: Higher resistance than glass microfibre. Very good up to 1000ºC; beyond this value it starts loosing its normal properties.
