Abstract: A filter element for releasable connection with a filter head a first end cap defining a first open aperture; a tubular construction of filter media being secured to the first end cap; and an axially extending neck, surrounding the first open aperture, having, an outer radial surface and an inner radial surface. The filter element includes a first linear to rotary motion conversion element, arranged to engage with a second linear to rotary motion conversion element on a valve element of the filter head so as to impart, when the filter element is moved linearly towards the valve element in a direction along a longitudinal axis, a rotational movement onto the valve element.

Abstract: A filter assembly is disclosed comprising a filter cartridge, a filter housing end part, and a filter housing main part, said filter housing main part being adapted for receiving said filter cartridge and for being connected to the housing end part by screwing, wherein said filter housing main part comprises a first longitudinal axis and a main opening, said main opening being defined by a first end portion, said first end portion comprising an upper, interrupted rim and a first threaded portion arranged below said upper rim; said first end portion comprising a recess arrangement comprising one or more axially extending recesses, said one or more axially extending recesses at least partially interrupting said first threaded portion; said filter cartridge comprises a second longitudinal axis and a first end cap, said first end cap comprising a central portion and a radial extension arrangement comprising one or more radial extensions extending radially away from said central portion; and wherein said radial

Abstract: A deaerator includes gas nucleation media and a porous barrier. The deaerator may include growth media between the gas nucleation media and the porous barrier. The deaerator may be part of a system for removing gas from a fluid, where the system includes a tank with a fluid inlet and a fluid outlet and having a fluid flow path from the fluid inlet to the fluid outlet, and where the deaerator is in the fluid flow path. A method for removing gas from a fluid includes passing the fluid through the deaerator defining a fluid flow path.

Abstract: A filter cartridge with flow travelling from inside to outside with a flow path in a bottom end cap to enter the cartridge has an anti-drain back valve to prevent cross-contamination to the clean side of the system during filter change-out. The anti-drain back valve moves away from the bottom end cap to allow inlet flow into the cartridge during filtering operation, and when flow ceases, the valve settles to the bottom of the cartridge to plug the flow path during service.
