A ring filter element for a filter device may include a connecting region and an axially projecting pin. The pin may include an arm via which the pin is connected to the connecting region. The arm may include a predetermined breaking point disposed spaced apart from the connecting region.

A device and method for removing debris from a process fluid are described herein. Specifically, a sanitary disc strainer includes a strainer body, a moveable guide rod assembly, moveable within the strainer body, a plurality of grooved discs stacked on the moveable guide rod assembly, and an actuator for moving the moveable guide rod assembly to compress and decompress the plurality of grooved discs.

A fluid cell for an assembly and for filtering oil includes a fluid cell housing with a housing opening and partly surrounds a housing interior, a housing cover attached releasably to the fluid cell housing for closing the housing opening, and a filter device arranged in the housing interior for filtering the oil, in which a filter element is arranged and which fluidically communicates with a raw oil line for conducting the oil to be filtered into the filter device and with a clean oil line for conducting the filtered oil out of the filter device. An oil reservoir is arranged in the housing interior for storing oil, which fluidically communicates with an oil reservoir line for conducting oil out of the oil reservoir, and a fluid cell valve device for closing and opening the raw oil line, the clean oil line, and the oil reservoir line.

A cleaning bucket structure for automatically purifying foul water is provides. The cleaning bucket structure includes an outer bucket, an inner bucket, a transmission member, a pumping member, a filtering member and a covering plate. The outer bucket has a receiving space. The inner bucket has a diameter which is smaller than a diameter of the outer bucket and is disposed in the receiving space of the outer bucket. The transmission member is disposed in the inner bucket. The pumping member is disposed in the inner bucket for receiving the transmission member therein. The filtering member is disposed in the inner bucket and surrounding the transmission member and the pumping member. The covering plate is disposed in the inner bucket and above the filtering member and includes a plurality of openings.

A method includes providing a computer-readable three-dimensional model of a filter medium including a plurality of segments, each segment of the three-dimensional model being configured to be converted into a plurality of slices that each define a cross-sectional layer of the filter medium, the filter medium including a first end defining a first cavity that extends from the first end along a predetermined direction that defines an undercut along the first predetermined direction; and successively forming each layer of the filter medium by additive manufacturing.

A filter assembly for a solenoid-actuated valve includes a filter band adapted to be disposed about a valve body of the solenoid-actuated valve. The filter band has a first end and a second end. The filter assembly also includes a locking mechanism to lock the first end and the second end together. The locking mechanism includes one of the first end and the second end having a slot extending therein and at least one aperture extending in communication with the slot and another one of the first end and the second end having at least one post to pass through the at least one aperture such that the first end and the second end lock together in a closed position.

An inlet filter is usable on a sprayer, such as a gravity-feed paint sprayer. The inlet filter can include a lip for placement on the top of the sprayer's hopper and a mesh screen for filtering a spray liquid medium, such as paint, as it is poured directly from its container into the hopper. The inlet filter removes the need for a paper filter, filter stand and transfer cup as is conventionally used in paint filtering operations.
