Abstract: A fluid filter system including a filter housing having an inlet chamber that surrounds the inner chamber that houses the filter cartridges. The filter cartridges are positioned in an involute configuration to channel rotationally inward flow of the fluid as it loses kinetic energy and velocity. The configuration provides superior filtering of fluids flowing therethrough and provides superior filter life.

Abstract: A fluid filter system including a cartridge filter housed in a tank having a standpipe extending from a bottom surface of the tank. The cartridge filter is positioned in the tank with the standpipe extending into an outlet tube in the filter. Fluids flow into the tank, through the filter, and out through the standpipe. The cartridge filter may include a seal in an upper portion of the filter for sealing the cartridge filter to the standpipe in a position that is above the contaminant laden fluids and debris that collect at the bottom of a tank during removal of a cartridge filter.
