A basket strainer insert having a body with one or more magnets disposed therein. The basket strainer insert includes a baffle to disrupt the flow of liquid through the basket strainer and facilitates the attraction of metallic particles to the body. The baffle has a plurality of lobes secured to the body with connection portions and separated from each other by gaps. The lobes may have an inward bend, an outward bend, or may be planar.

The claimed invention relates to systems, devices, and methods of using the devices for eliminating air locks by using a filter cartridge with a truncated cone shaped lid that allows air to naturally flow to the highest point of the filter cartridge. The lid including a hole for releasing air that can slow or stop the filtration process. The filter cartridge further including a foam spacer to prevent filter media from escaping the filter cartridge and allow air to be released from the hole at the top of the filter cartridge.

A filter cartridge for a fuel circulation circuit of a vehicle. The filter cartridge comprises a cartridge body identifying a filtration chamber. In said filtration chamber, the filter cartridge further comprises at least one filter insert which divides said filtration chamber into a dirty chamber containing fuel to be filtered and a clean chamber containing filtered fuel. The filter cartridge further comprises a ventilation device suitable to ventilate in the dirty chamber, wherein the ventilation device comprises at least one ventilation duct placed in an upper area of the filtration chamber in which the air floating in the fuel accumulates. Said ventilation duct has a plurality of ventilation holes mutually spaced from one another through which the air is removed from the filtration chamber.

A filter element includes a first end cap, a second end cap, and a ring of filter media disposed between the first end cap and the second end cap. The ring of filter media circumscribes a central cavity. The filter element also includes an air-bleed conduit axially extending through the central cavity. The air-bleed conduit includes a first portion integrally formed with the first end cap and a second portion integrally formed with the second end cap. The second portion is configured to fluidly connect to the first portion.

A filtering device and a filtering method are provided. The filtering device includes a bubble filtering system. The bubble filtering system at least includes a first bubble filtering system and a second bubble filtering system. The first bubble filtering system configured for performing a first bubble filtration in the solution. The second bubble filtering system configured for performing a second bubble filtration in the solution. Filter fineness of the second bubble filtering system is higher than filter fineness of the first bubble filtering system.

A filtration cartridge of a liquid purification device that consists of a filtration zone (1) and a venting zone (6), said filtration zone in turn consists of a housing (2) filled with a filtration material (3) and not less than one opening (5) made in the bottom (4) of the housing (2), said venting zone consists of fixation means (7) and a lid (8), performed so that the filtration material (3) has a multi-clustered interconnected structure, and the venting zone (6) is formed so as to retain and preserve the main structure of the filtration material (3) inside the housing (2) of the filtration cartridge, by means of the fixation means (7) being the first retention barrier and made as a grid, the size of mesh (11) of said grid does preferably not exceed the average size of the filtration material cluster, and the lid (8) is made as a second retention barrier and formed, with meshes (12) comprising net sections and a top point (9) of the lid (8) is positioned at a distance preferably not more than 1 cm above the fixation means (7).

Methods and systems for recovering retained filtered fluid are provided.

An in situ system of filter rejuvenation has a fluid inlet on a first side of a reaction chamber, a fluid outlet disposed on a second side of the reaction chamber, a filtration chamber with a first wall comprising a ceramic glass material with a pass-band in the infrared spectrum. The filtration chamber is in fluid communication with the fluid inlet and the fluid outlet so that a fluid introduced into the inlet passes through the filtration chamber and exits through the fluid outlet. The system has at least one infrared heating element configured to transmit infrared energy within the pass-band of the ceramic glass material to heat the filter medium disposed within the filtration chamber to a temperature of at least 260° C., which can gasify contaminants without combustion.

A gas-liquid separator includes: a housing including a gas inlet, a gas outlet, and a water storage section at a lower side of the gas inlet and the gas outlet; a collision wall provided inside the housing to collide with a gas that contains water introduced from the gas inlet to separate the water from the gas by adhering the water thereto while changing a flow direction of the gas; and a downflow wall provided inside the housing to introduce the water falling from the collision wall into the water storage section and change the flow direction of the gas.

A method of cleaning a regenerative filter having a filter housing having inlet and outlet zones, a fluid path provided between the inlet and outlet zones, and a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path, the method comprising draining all fluids from the filter housing, refilling the filter housing with fluid to an optimum level, and initiating a cleaning sequence of the filter housing with the fluid at the optimum level. The cleaning sequence can comprise agitating the tube sheet, initiating a pump to effectively air scour for a first predetermined amount of time, dwelling for a second predetermined amount of time, and repeating the agitating, initiating, and dwelling until a third predetermined amount of time is complete.
