A filter assembly includes a manifold with a base and a support ring. The support ring is received within the base such that the support ring is rotatable relative to the base. A housing of the filter cartridge has an interface positioned at an outer surface of the housing. The interface is configured to engage with a post of the support ring in order to mount the filter cartridge to the manifold.

A housing assembly, portable filter system using the housing assembly and methods of mounting a filter element in a housing assembly are provided. The housing assembly is usable with filter elements of different types. The housing assembly includes a housing body having an open end and being attached to a filter head. The filter head includes a first housing sealing interface configured to sealingly mate with a filter element of the first type and a second housing sealing interface configured to sealingly mate with a filter element of the second type. A cover member removably attaches to the housing body and includes a third housing sealing interface configured to sealingly mate the filter element of the second.

A sorption filter cartridge for a sorption filter element includes a fluid permeable housing. The housing encloses a plurality of housing rooms that are separated from each other. Each housing room receives at least two layers of non-woven fiber material and a granulate portion comprising at least one sorbent. The granulate portion is sandwiched between the at least two layers.

Embodiments of the invention provide a filter for use in filtering a fluid slurry that includes particles of varying size, such as pool water including debris. The filter is in electrical communication with a sensor and includes a housing having an inlet to receive the fluid slurry, an outlet, and an internal chamber. An actuator can be coupled to the filter media to move at least a portion of the filter media to vary a dimension of the pores. The filter also includes a controller connected to the actuator that is capable of receiving a signal from the sensor and controls the actuator to change the dimension of the pores based on the signal.

A spin-on fluid filter with improved attachment and sealing with the filter head. The filter has a gasket positioned at the end of threads used to connect the filter to a filter head. The described design protects the gasket from excessive engine heat, cat or tear damage during installation, and the roll out effect of installation torque. In addition, the described attachment provides gasket protection and uniform compression of the gasket. The gasket can be any type that provides a seal which keeps external threads on the filter and the filter head dry.

An embodiment of the present disclosure provides a liquid processing apparatus, including: a housing having an upper end opening and a sealed bottom; a cover covering the upper end opening of the housing; a sealing portion provided inside the housing, it being sealed between the sealing portion and an inner wall of the housing, and a sealed accommodation space being formed between the sealing portion and the bottom of the housing; a processing portion provided within the accommodation space and configured to process a liquid flowing into the accommodation space, an upper end of the processing portion having a guide portion; a liquid inflow portion and a liquid outflow portion provided at an upper part of the housing. According the embodiment of the present disclosure, the liquid inflow portion and the liquid outflow portion are provided at the upper part of the housing, which may facilitate installation of the liquid inflow portion and the liquid outflow portion. A seal ring for sealing is provided between an inner wall surface of the guide portion and an outer side edge of a connector, hence, the processing portion may obtain a more reliable sealing effect.

A composite filter cartridge, comprising a filter cartridge body provided with two filter devices. Each filter device is respectively provided with a support component which fixes the filter device, and the filter devices are arranged in a linear manner and fixed with respect to one another. Each filter device is respectively provided with an independent housing, a filter module and a filter water channel, the filter module and the filter water channel being arranged within the housing, the filter water channel sequentially comprising a water inlet cavity and a water outlet cavity, the water inlet cavity and the water outlet cavity being connected via the corresponding filter module.

An air filter cartridge (1) for an air intake system for a vehicle engine extends along a main axis (X-X). The air filter cartridge includes a filter element (5), suitable to filter the air sucked through the filter element and having extension along the main axis (X-X) and an internal structure (3) that extends inside of the filter element (5). The internal structure (3) identifies a plurality of ducts (30) fluidically independent from each other through which the filtered air flows separately. Each duct (30) extends between an inlet mouth (31), placed in proximity of a respective filter element portion (51), and an outlet mouth (32) placed in proximity of the head element (2) in such a way as to induce the intake of air through each duct (30) through the respective portion of the filter element (51).

A method for recycling and filtering rolling oil implemented for a rolling mill M requiring a rolling oil nominal flow rate comprised between 4000 l/min and 30000 l/min in an oil recycling and filtering plant having a circuit including, successively, according to the flow direction of the oil: a dirty oil tank, collecting the rolling oils coming from the rolling mill, a filtering system including several oil filtering devices configured to perform an oil filtering in parallel, a clean oil tank from which the rolling mill is fed with rolling oil at the nominal flow rate. The unclogged muds undergo a secondary treatment by continuous and turbulence-free decantation, thanks to a feed-in of the decanter with mud regulated by a pump.

An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.
