A transmission oil filter is assembled from a filter element, a base, and a cover. Each of the three pieces extends beyond the filtration media to form an inlet channel. The inlet channel is low enough to fit under a valve body. Placing the inlet in this channel ensures that the inlet draws transmission fluid at road gradients and acceleration rates at which an inlet under the filtration media would draw air.

Support and drainage materials, filter including the materials, and methods of use are disclosed.

The Edo Cup 2.0 is an open, suspended, accordion type paper single cup finable completely biodegradable and recycle-able beverage disposable filter. The filter can be in several shapes and sizes and may display corporate logs, up to an including religious symbols, sayings and holiday messages. The filter may enclose flavors (in the filter paper) or be pre-soaked in flavors prior to packaging for sale.

Disclosed are processes for producing molded polyurethane elastomers and products, such as filter end caps, that include such elastomers. The elastomers are the reaction product of a non-foaming reaction mixture comprising an isocyanate-reactive composition and an organic polyisocyanate prepolymer with an internal mold release agent.

A separator for a separator device, for example a final separator for a final separator device for separating water from a liquid such as oil and/or fuel, may include a filter body including at least one filter material through which the liquid can flow. The filter body may have a first side and a second side. A nanofibre layer may be disposed on the first side in at least one region. The nanofibre layer may be configured hydrophobic. According to an implementation, the nanofibre layer is treated to produce the hydrophobic property. The filter body may have a porosity on the first side that is smaller than on the second side.

A filter frame, a filter cartridge, and an assembling method of the filter cartridge are provided. The method has the following steps. A filter core and a filter frame are prepared. The filter frame has a glue-cutting segment. Glue is coated around an outer wall of the filter core, and then the filter frame, which is mounted around the filter core, is pushed toward the glue to make the glue-cutting segment press the glue until the glue is cut into two parts. The inner glue part disposed between the filter core and the filter frame seals the filter cartridge. The outer glue part is disposed on an outer side of the filter frame, and is superfluous and removed. The glue-coating is combined with the mounting of the filter frame, thereby saving time and effort.

A water separation filter is provided with a first compartment including a particulate filter and a second compartment including a hydrophobic filter for removing particle contaminants and water from a fuel flowing through the filter. Inlet and outlet fuel line couplings are provided so that the water separation filter can be installed as an in-line filter between a fuel tank and a combustion engine.

A filter medium includes a plurality of layers each including an undulating strip of solidified material.

A method for manufacturing a filter includes providing a computer-readable three-dimensional model of the filter, the three-dimensional model being configured to be converted into a plurality of slices that each define a cross-sectional layer of the filter, and successively forming each layer of the filter by additive manufacturing.
