Pleated PP fiber filter cartridges

SEPRA PRETREAT is a range of cartridges very suitable for the removal of solids from  water to be supplied to reverse osmosis plants.

Filtration takes place by means of a polypropylene pleated membrane with absolute filtration degree (beta = 5,000 => efficiency at the nominal filtration rating > 99.98%).

The cartridges are built with raw materials selected in compliance with FDA CFR21 regulations in order to guarantee their safe use on food liquids. This type of cartridge tolerates a variety of chemical compounds used in continuous filtration and cleaning. We offer 30" lenght with 226-end fittings as standard available in stock, although lengths from 10 "to 40" are available on order, as well as many types of attachments to adapt the cartridges to every need and container.

The high surface area of ​​SEPRA PRETREAT cartridges guarantees a long life and low initial pressure drops.

All cartridge support components are constructed in high-purity polypropylene and the cartridges are fabricated and assembled in a sterile environment to minimize the possibility of contamination.
