Our depth cartridges FR-N Series are designed to obtain a high efficiency and filtration of various liquids having impurity. Using only 100% pure polypropylene they are manufactured through state of the art technology. They are generally used in applications that require extremely high quality filtration. During the manufacturing process, the polypropylene is mixed with compressed hot air. Then it is stratified on a rigid polypropylene core through a continues and constant rotating movement. This process infuses and intersects the polypropylene fibres amongst themselves. This creates the so called “Depth Cartridge” guaranteeing a uniform filtration along all the surface of the cartridge. The Polypropylene fibres used are always and only of first choice which processed at high temperatures welds them together eliminating any possibility of losing particles or residuals. The range vary from 1 to 90 micron and standard lengths are 9”3/4 to 40”. The cartridges are made up as one whole piece no matter what length. The FR-N Cartridges are fully tested to achieve at least 95% filtration efficiency. This means that a 10 micron FR-N Cartridge will filter 95% of particles having a diameter of 10 micron or more. The extraordinary filtration capability of the FR-N cartridges is obtained thanks to its wide filtering surface and compactness which is distributed along all the surface of the cartridge itself. The cartridges need the be changed when a loss in pressure drop is detected or in any case when the specific filtering application requires it.


The FR-N cartridges can be used as end-line filtration or as prefiltration.
