Fibre Filters with inorganic binder
Recommended filters for environmental analysis and controlling both air and water pollution.
- Made of 100 % borosilicate glass fibres with binders
- Glass fibre filters capture fine particles down to 1 µm from liquids, in air, gases and aerosols with even 0.3 to 0.5 µm being absorbed
- Extremely low content in alkali-earth metals
- Chemical stability: It keeps all its properties in contact with acid solutions (except hydrofluoric acid) and basic solutions at moderate concentrations
- Stabile at temperatures up to 500 °C
- Gravimetrical analysis of organic and inorganic impurities in water and waste water according to DIN 38409 and EN 872 (suspended particles)
- Measurement of immission, measurement of dust in air and gases, monitoring of the efficiency of filtration and dedusting, monitoring the combustion air of power plants and of the steel and iron industry
- Measurement of dust release in workplace and production processes and the purification of compartment air
- Measurement of scintillation
