Main Features
Quartz microfiber filters
Atmospheric controls of emission, immission and estudies of metals in the air
Filters made exclusively with pure quartz (Si O2) microfibers, free from any type of bonding agent or other substances
Subsequently treated thermally to achieve very low levels of heavy metals
Specially recommended in controls of emission in industrial smokestacks specially when a very pure filter is required or when the physical or chemical conditions of the gases are extreme: temperature higher than 500°C or stronger acid concentration (except HF)
It made two qualities, one standard and one more pure, heat-treated for minimal metal content:
Chemical stability: It have an excellent chemical stability against acidic gases such as SO2, HCl, SO3, SO4, NO, NO3, except HF. With hardly any loss of mass of the filter through possible chemical reactions
Thermal stability: It is resistant to operating temperatures up to 900°C
Permeability: Excellent behavior during the passing of significant volumes of gases, which makes it ideal for the use in high-volume detectors.
Retention of particles: The structure and the physical and chemical properties of quartz microfibers are such that these filters have a high level of retention of particles not only on the surface but also in the internal structure of the frame.

Control of emissions in industrial chimneys
Control of inmissions in high volume detectors
Gravimetric determinations on gases
