FA Wound

Our Polypropylene wound cartridges are part of the depth and deforming cartridge series. They are manufactured using only 100% pure non-toxic polypropylene yarn. This series offers an excellent ratio between cost/quality, even though usually referred to as “economic-type” they are manufactured so as to guarantee a high nominal filtration level.
WOUND CARTRIDGE OPEN-END WASH – OIL RESIDUAL 0,2%
This yarn is manufactured using machinery that allows a shorter production period and therefore a more economically priced product. The raw material used for this product is exactly the same as the Wash Carded type. The only difference is that it is not carded after the process of extrusion & twist but simple manufactured around a BCF (by extrusion spun yarn) making it compact and uniform. Although less compact than the carded one, it still yields a satisfying filtration performance at lower costs. Amongst the inconveniences of this cartridge is that at the beginning of use it creates a small amount of foam that after a short period will disappear. Even if the foam is non-toxic, in certain applications it could cause minor problems to the post-filtration unit. Therefore it is important to know where such cartridge will be applied to avoid any inconvenience. The inside core of the filter is rigid and in Polypropylene which guarantees stability. The lengths range from 5” to 40” and the micron range from 1 to 100.
