    摘要： A filter element has an upstream and downstream side. A filter media assembly of the filter element has an upstream side and a downstream side and has a first filter media layer and a second filter media layer that is adjacent to the first media layer. A substantial portion of the first layer and second layer are uncoupled, and at least one of the first media layer and second media layer comprises binder fiber. The second media layer has a mean flow pore size equal to or smaller than the first media layer. A support layer system is adjacent to the downstream side of the filter media assembly, and a first wire mesh layer is adjacent to the support layer system. At least the first media layer, second media layer, support layer system, and first wire mesh cooperatively define pleats at a pleat packing density of greater than 125%.

    摘要： A filter including a first flow face extending along a lateral direction and a transverse direction of the filter, wherein the first flow face includes at least one contaminant retention layer first edge and at least one flow defining layer first edge, a second flow face spaced in an axial direction from the first flow face, wherein the second flow face extends along the length and the width of the filter and includes at least one contaminant retention layer second edge and at least one flow defining layer second edge, at least one contaminant retention layer extending from the contaminant layer first edge to the contaminant layer second edge, and at least one flow defining layer adjacent to at least one of the contaminant retention layers, the at least one flow defining layer extending from the flow defining layer first edge to the flow defining layer second edge, wherein at least one of the flow defining layers defines at least one fluid flow path in the axial direction as fluid moves from the first flow face toward the second flow face.

    摘要： The freezing of liquid can be prevented and the breakage of a device can also be prevented even when the liquid freezes. A filter case that internally includes a filter element including a filtration member having a substantially cylindrical shape that filters the liquid and an inner tube having a substantially cylindrical shape provided inside the filtration member. The inner tube includes a partition plate that covers a hollow portion of a side surface. A heater provided on a bottom surface of the filter case includes a substantially rod-shaped heating unit. The heating unit is inserted into a space surrounded by the side surface and the partition plate of the inner tube via a first hole formed at a position overlapping with the hollow portion of the inner tube in the first plate that covers a lower end of the filtration member.

    摘要： Provided is a strainer capable of removing bubbles contained in a liquid and preventing the removed bubbles from mixing with the liquid again. The strainer includes a second filtration section having a substantially cylindrical shape with both ends connected, formed by folding a thin plate-shaped filter medium in a pleated shape, which is provided inside a first filtration section having a substantially cylindrical shape with both ends connected, formed by folding the thin plate-shaped filter medium in a pleated shape, without coming into contact with the first filtration section. An outer cylinder having a substantially cylindrical shape having a height higher than that of each of the first filtration section and the second filtration section is also provided outside the first filtration section, without coming into contact with the first filtration section. In addition, an upper plate, having a substantially discoid shape covering an upper side of each of the first filtration section, the second filtration section, and the outer cylinder, is formed with a plurality of first air vent holes between the outer cylinder and the first filtration section and formed with a plurality of second air vent holes between the first filtration section and the second filtration section, in a plan view.
