Filter materials - Import export

In the field of highly efficient filter materials, we have developed proprietary synthetic filter media produced with various fiber diameters and available in different grammages. With a particle separation of up to 99,99%, our media also feature a low pressure drop together with high softness. Due to endless fibers no fiber shedding occurs. We support our customers with filter media material as roll goods for respirator masks or pleatable material.

When it comes to filter material, there are a few points to consider. The filter material should have a large surface area. This ensures a good exchange rate between exhaust air and filter material and provides sufficient space for microorganisms to colonise. The filter material must be designed in such a way that it has a good water holding capacity. The colonised microorganisms are only viable in a moist environment. In general, different filter materials are used in one batch. The reason for this it ensures both a good stability of the filter bed and a larger surface. In addition, the added microorganisms must be sufficiently supplied with inorganic nutrients and trace elements, unless this is provided by the composition of the exhaust air. The temperature inside the biofilter system plays a decisive role as well. Temperatures between 5 °C and 40 °C are favourable for the microorganisms to work properly.

Knight Optical can offer you Stock and Custom Colour Glass Filters, for use within Inline Cameras in a range of materials of brands such as Schott, Kopp and CDGM. Depending on the achievable wavelength and desired affect you need for the Inline Camera we can find a suitable material for your application. Colour Glass Filters are good for selecting a particular wavelength to be absorbed so that the high out of band blocking in achieved. With regards to the use in Inline Cameras, Colour Glass Short pass Filters are more desirable as they cut out the IR wavelengths mean the imaging is not saturated with the IR giving the image better clarity. Colour Glass Filters are polished sheets of special glass that have been cast with a dye. Colour Glass Filters generally are relatively cheap and very stable. The disadvantage with them is that they are only available in a relatively small number of variants, and so can be restrictive in shortwave selection.  For More Info see PDF...

CF 30 G equipment is supplied completely assembled and ready for operation. The dust collection unit is suited for intermittent operation only, because regular cleaning of the pocket filter element in certain intervals is an absolutely must for the proper operation of the equipment. The cleaning intervals will depend on the operating conditions and must be established by experience. Normally cleaning intervals will be between operating times of 30 minutes to two hours. It is a prerequisite for sufficient and intensive cleaning of the filter cloth that dust collecting is interrupted during cleaning to achieve static pressures on the filter material. A retention time of 1 - 2,5 minutes between the end of the suction and the beginning of the cleaning process is therefore required. The filtered air must be removed outside - do not lead back to closed rooms!
