A filter cartridge for use in a fluid filtering system, constructed to induce rotational flow in the unfiltered fluid, includes a pleated filter sleeve in which the individual sleeves are slanted relative to the sleeve circumference in a direction opposite to the direction of the rotational flow fluid. The slanted pleats can be constructed by creasing a sheet of filter media at alternatingly shorter and longer widths to form pleats having relatively shorter front legs and relatively longer back legs. The shorter front legs bias the pleats in the counter-rotational direction. Apparatus for manufacturing the pleated sleeve includes a pleater roll having pleater wires spaced to form the alternatingly shorter and longer pleat widths.

A filtering system comprises an outer housing into which fluid enters tangentially through a side inlet port to create rotational flow therein. Solid contaminants which clog filtering media are precipitated to the bottom of housing through action of centrifugal force in rotational flow. An inner can, disposed within the housing shrouds a filter cartridge. Unfiltered fluid flows rotationally into the inner can and is filtered through a vertical cylindrical filter cartridge. Filtered fluid flows up through the center of said cartridge to a clean fluid chamber below a domed cover and exists downwardly through a vertical outlet tube extending through the filter cartridge to an outlet port in the bottom of the housing. Gases in the system are collected in the clean fluid chamber and transported by the fluid flow through the outlet tube, thereby automatically purging gases from the filtering system.

The disclosure concerns a swimming pool-type filter comprising: (a) a stainless steel vertical cylindrical vessel with a removable domed cover and a horizontal partition sealed between the periphery of the cover and the open vessel, from which partition suspends a plurality of filter cartridges; and (b) a helically coiled heat exchanger coaxial of the vertical axis of the vessel and having its horizontal inlet and outlet ducts extending through the side of the vessel and supporting the coil. The filter cartridges fit inside and around the outside of the helical coil for easy removal, replacement and cleaning by lifting the partition after the cover has been removed. The inlet and outlet ducts for the liquid or water to be filtered and warmed are in the bottom of the vessel, with the outlet duct extending up through the vessel to the chamber above the partition in the domed cover.

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.

A fluid filter system with cartridge filters housed in a tank in which each cartridge filter has a lift tube positioned concentrically within each cartridge filter. The lift tubes extend from a support plate, which divides the tank into a raw fluid chamber and a processed fluid chamber, toward a tank cover. The lift tubes have inlet ports proximate to the tank cover so that the fluid surface in the tank is maintained at or near an upper end of the cartridge filters. This configuration enables the lift tubes to exhaust excess air in the tank through the lift tubes and out of the filter system through outlet ports in the processed fluid chamber. By exhausting air from the filter system, the capacity of the system is not compromised by the air and the expected life of the cartridge filters is not reduced.

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.
