A disposable cleaning-free paint pot comprise a pot body and a pot lid covering an opening of the pot body, the pot lid including a pot lid connector and a feed hole disposed in the pot lid connector, the adapter including an external thread disposed at an outer wall, positioning blocks disposed at an inner wall thereof, a press plate and a clamping cam; the pot lid joint is including positioning slots engaging with the positioning blocks and an annular groove for the clamping cam. The paint pot from cleaning after spray coating, the cleanliness of paint pot is guaranteed, so that the paint pot is fitted on spray gun rapidly, and the paint can be mixed in the pot body.

A filtering apparatus includes a screen assembly removably positioned within an inner cavity of a screen chamber. The screen assembly includes a frame portion at a first end and a screen portion extending from the frame portion to a second end. The frame portion includes an end block and frame members interconnecting the end block and the screen portion. The screen portion includes an outer screen and an inner screen disposed within an interior space of the outer screen. An outer wall of the outer screen and an outer wall of the inner screen each includes a plurality of openings. The screen chamber includes a removable end cover with a key for rotationally locking the screen assembly in the inner cavity. A screen manifold may include a first fluid path including the screen chamber, and further including a bypass fluid path having a bypass valve.

A canister based transmission filter system, which may be integrated into transmission reservoirs. The system features a filter in the shape of a cylinder or a polygonal prism, and a corresponding transmission filter receiver. The filter has a pleated filtration surface with an integrated magnet, and is inserted into the receiver without need of additional screws, clips, nor bolts. The receiver closes off transmission fluid flow when filter is being changed to prevent contamination of the surroundings, and opens when the filter is installed to allow for filtration. Filter may be quickly changed using only the L-pin provided, and locks itself in place during installation.

A filter insert for being removably arranged in a filter housing defines a first end and a second end opposite the first end, including a closing arrangement at the first end of the filter insert for controlling opening and closing, respectively, of an aperture, and an actuation arrangement operatively connected to the closing arrangement for actuating the closing arrangement, wherein the actuation arrangement is positioned at the second end of the filter insert and wherein the actuation arrangement is accessible for external contact at the second end of the filter insert.

A filter insert for being removably arranged in a filter housing includes a first connection arrangement for engaging a corresponding second connection arrangement of a filter housing lid for a connection to the filter housing lid. The first connection arrangement is arranged to simultaneously prevent a relative rotational movement between the filter insert and the filter housing lid and allow a relative axial movement between the filter insert and the filter housing lid.

The filter assembly includes a threadless closure system for sealing a filter element of the filter assembly within a bowl of the filter assembly. The bowl is fluidly connectable to opposing fluid transfer passages. The filter element and a cover element connected to the filter element are received into the bowl. The filter element is retained in the bowl via a pin of the filter assembly that engages the cover element. The filter element may be removed and replaced without the unscrewing of threads exposed to an external environment external to the filter assembly during typical use of the filter assembly.

A filter pad for use in a dewatering container is presented. The filter pad is configured to fit within the interior cavity and substantially line the interior surfaces. Material, which is usually liquids and slurries, is added to the container with the filter in place and gravity is used to filter the sediment, while the water is released through a release nozzle. The solids are retained in the filter pad for later disposal. The filter pad has a portion that can be selectively opened and is configured for placement substantially adjacent the door to permit selective egress of contents of the interior cavity.

An environmental waste water filtering system, including a bucket, the inside of which tapers into a funnel portion that leads to a strainer. The funnel has an exit tube that extends 3 inches below the bucket wall and may be inserted into a drain such as a toilet drain pipe. The inside of the bucket and funnel portion forms a fluid debris chamber. When fluid containing particulate matter is poured into the fluid debris chamber, the particulate matter is removed from the fluid portion as the fluid passes through the strainer and then into the toilet drain pipe. Once all fluid drains from the fluid debris chamber, the captured debris may be poured into a trash bag and disposed of. Optionally, a disposable straining filter bag may be positioned in the fluid debris chamber so that even finer particulate matter is removed from the fluid for disposal with the bag.

The present development is a septic tank or wastewater treatment tank outlet filter cleaning device. More specifically, the device is an outlet filter cleaner for a slotted filter used to reduce solid waste transfer into a septic tank effluent. The device comprises a central shaft with at least one cleaning disc, wherein the cleaning disc comprises a body which is mounted on the shaft and wherein a plurality of fingers protrude from the body, preferably in locations substantially identical to the positions of the openings in the wall of the tube.

A filter insert is provided for being removably arranged in a filter housing and includes a first actuation arrangement positioned at a first end of the filter insert, wherein the first actuation arrangement is adapted for being actuated by a corresponding second actuation arrangement of a filter housing lid for controlling a relative, axial movement between the filter insert and the filter housing lid.
