Engineered from high quality recycled plate glass (not bottles), Prism Si4 is Engineered to Outperform and is supplied with 2 ‘Grain Curve’ options, medium grade and fine grade. Now, you can select a filtration media that combines the best features of different media types – high dirt loading, low operational pressure differential, anti-fouling properties, anti-compaction properties & more – Prism Si4.

The durability of Prism Si4™ is outstanding. Its integrity is assured for at least 30 years.Prism Si4™ offers high filtration performance, >1um particles may be eliminated in optimum conditions.

 

Properties such as the microscopically smooth surface and aseptic characteristics of Prism Si4™ Technology prevent bacteria from proliferating within filters, which eliminates the need of dosing chemical biocides. Prism Si4™ Technology includes, among other unique qualities, a special grading curve calibration technology.

This is known as ‘Anti-Compaction’ technology.How does Prism Si4 avoid compacting and segregation? To do that, after material classification, and grinding process, the grains are separated by sizes via a light separation procedure.

Every different kind of glass and colour projects a different wave within the light spectrum. The grain processing machines recognise the type of glass via light refraction, and a compressed air flow separates and grades glass pieces as they fall in a vacuum chamber.

After this process, exact quantities of every grain size are mixed to create a curve able to avoid compacting. There is an exact percentage of every separate grain size inside each bag of Prism Si4. For example in the STAGE 3 ultrafine grade there is 21% of 0,1mm grain size. No more or less!

This is a key benefit of Prism Si4™, as not only does it provide equalized particle entrapment throughout the filter bed by preventing ‘clumping’ and ‘channelling’, it also contributes to a very low operational pressure loss during filtration minimising energy consumption.
