20" Melt Blown FR-N/AB 20 Micron

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.
