Compound Wind Filter Cartridges

Compound Wind Filter Cartridges

Two different micron retention's being used on the same filter cartrdige. For example: a 1 micron winding pattern would be wound as an inner wind of the filter cartridge, then a 50 micron winding pattern would be then be wound as the outer wind. This would give the user the ability to trap larger particulates as well as smaller particulates. This filter is becoming very popular in the market place today. In some applications it is replacing multi-stage filtration, reducing cost of filtration. Normally the smaller micron retention size is wound as the inner wind and the larger micron retention size is wound on the outer wind. This can be reversed depending upon the application. The filter can be manufactured using different types of media's, on different types of cores, to different size O.D.'s, and lengths. It is possible to wind one type of media to particular micron retention and wind another type of media to different micron retentions. Different end treatments, end caps and configurations can be installed.
