A removable filter cartridge includes a filter housing containing a filter, a sealing valve coupled to an open end of the filter housing and configured to removably couple the removable filter cartridge to a filter head. The sealing valve has an open position and a closed position that seals the filter housing, and is configured to maintain a seal of the filter housing while uncoupled from the filter head. A sealing valve includes a first end to be removably coupled to a filter head and a second end to be coupled to a filter housing to form a removable filter cartridge. A method of retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve to the filter housing to form a removable filter cartridge, and removably coupling the removable filter cartridge to the filter head.

A center tube and a central fluid supply tube combination includes a center tube body defining a longitudinal length, and a central reservoir. The center tube also includes an apertured annular wall extending axially the majority of the longitudinal length, and a first annular solid wall extending axially from the apertured annular wall. A central fluid supply tube is disposed in the central reservoir, and includes a second annular solid wall that is radially surrounded by the apertured annular wall of the center tube. The second annular solid wall defines a supply passage with a fully circular flow flux.

A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

Filter elements and filter systems are provided. The filter element allows for a reversed flow of fluid through the filter element when flowing from a first port to a second port of a filter head of the filter system. The filter element includes a standpipe in a central cavity of a tube of filter media that is fluidly connected with an exterior of the tube of filter media by a radial flow conduit and an axial flow tube.

A pedestal for use with a canister filter system and a filter element for positioning and retaining the filter element in the canister filter system includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. Also, the pedestal includes an annular wall that terminates at a bottom free end, and that defines a slot that extends axially upwardly and circumferentially from the bottom free end. A flow aperture extends through the annular wall that is disposed axially above the slot.

Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a key slot disposed on the first housing end and a housing key element protruding from the first housing end toward the second housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element includes filter media and an endplate disposed on the first filter end. The endplate includes a central endplate opening, a key element configured for engagement with the key slot, and an installation guidance element formed along the central endplate opening. The installation guidance element is configured for engagement with the housing key element.

A filter element includes a first end cap, a second end cap, and an intermediate end cap disposed between the first end cap and the second end cap. A ring of first filter media circumscribing a first central cavity is disposed between the first end cap and the intermediate end cap. A ring of second filter media is disposed between the intermediate end cap and the second end cap. The filter element also includes an air-bleed conduit axially extending through the first central cavity and comprising a first portion integrally formed with the first end cap and a second portion integrally formed with the intermediate end cap and configured to connect to the first portion thereby forming a conduit for transmitting fluid.

A filtration system comprises a filter head assembly comprising an outlet slot, valve element, and latch element. The valve element is in fluid communication with the outlet slot and includes an open position and a closed position. In the open position fluid flow travels through the outlet slot. In the closed position fluid flow is prevented through the outlet slot. The latch element is configured to lock the valve element in the closed position. The filtration further comprises a filter cartridge structured to engage the filter head assembly. The filter cartridge comprises a first and second filter end. The filter cartridge comprises filter media and a keyed element disposed on the first filter end. The keyed element is structured for engagement of the latch element, wherein the engagement unlocks the valve element causing the valve element to be in the open position.
