A filtration system including a housing defining an internal volume. The housing includes a housing first end, a housing second end, and a first coupling member formed in the housing. The housing first end is an open end. The housing second end is a closed end. A filter element is positioned within the internal volume of the housing. The filter element is configured to engage the first coupling member. A filter head is provided. A seal member is disposed between the housing first end and the housing second end. The seal member provides a radial seal directly between the housing and the filter head.

The present invention discloses a portable kitchen ventilator for a pot body, which includes a housing, an oil-blocking guard, a filter net assembly and a fan assembly, where the oil-blocking guard is provided at a lower part of the housing and covers a range to filter oil smoke; the filter net assembly is located in the middle of the oil-blocking guard, and is connected to the fan assembly; the oil smoke is absorbed via the fan assembly, and filtered via the filter net assembly, and the filtered gas is discharged from an air outlet. The portable kitchen ventilator of the present invention is placed on a pot body during use, and is provided on the pot body via the oil-blocking guard, and then the fan assembly is started, and oil smoke generated from cooking is pumped away, the oil smoke around the pot body is directly adsorbed.

A filter adapter holds a filter unit and corresponding personal protection equipment. The filter adapter can be connected to a filter device and can thus be used together with a filter device. The filter adapter is suitable for holding a filter unit and can be connected to a filter device. The filter adapter includes: a connecting structure for connection to the filter device, a holding structure for holding the filter unit, and a contact surface for sealing contact with a protective suit.

A filter that is retained in a shell housing by the use of a snap connection. The filter includes an endplate having snap features that interact with a groove in an inner portion of the shell housing. The groove may extend 360 degrees around an inner circumference of the shell housing. Accordingly, when the shell is unthreaded from the head for service (e.g., during a filter replacement service), the shell only needs to be displaced the length of the inner radial seal interface between the shell and the head, not the entire length of the filter media thereby minimizing the stroke length needed to service the filter assembly.

A filter for compressed air systems is provided. The filter includes a filter housing with a filter therein between an air inlet and an air outlet. Compressed air flowing between the air inlet and the air outlet passes through the filter housing and the filter element. A base is removably fastened to the filter housing which may be separated from the filter housing to allow the filter element to be removed and replaced.

An oil and air separator includes a lower housing defining in part a chamber within which oil may collect; an upper housing including a lower end threadingly engaged to an upper end of the lower housing; and a filter assembly threadingly engaged to the upper housing; wherein a lower portion of the filter assembly is disposed within the chamber when the filter assembly is threadingly engaged to the upper housing and the upper housing is threadingly engaged to the lower housing; wherein the filter assembly includes a filter block including a plurality of parallel lumens extending through the block; and wherein a continuous fluid pathway exists through the oil and air separator, the continuous fluid pathway extending from a fluid inlet port disposed in the upper housing, downward through a first passageway about the filter assembly, into the chamber, through a lower end of the filter assembly, upward through the plurality of parallel lumens extending through the filter block, through an upper end of the filter assembly, and through a second passageway leading to a fluid outlet port disposed in the upper housing.

Provided is a filter including a housing, a cover plate, a support seat, a connector, a metal rod, a tap, a mounting block, and a locking bolt. The cover plate is provided with a mounting hole and a threaded hole. The support seat penetrates through the mounting hole. The connector is disposed in the support seat. One end of the metal rod is connected to another end of the connector. The tap is disposed in the housing and connected to another end of the metal rod. The mounting block is provided with a receiving recess on one side of the mounting block and a reference surface on another side of the mounting block. The reference surface has a stop hole and a connection hole that are connected to the bottom of the receiving recess. The reference surface abuts against the side of the cover plate facing away from the housing.

A filtration system including a housing defining an internal volume. The housing includes a housing first end, a housing second end, and a first coupling member formed in the housing. The housing first end is an open end. The housing second end is a closed end. A filter element is positioned within the internal volume of the housing. The filter element is configured to engage the first coupling member. A filter head is provided. A seal member is disposed between the housing first end and the housing second end. The seal member provides a radial seal directly between the housing and the filter head.

The present disclosure relates to fine filter part kit (63), comprising a replacement fine filter part (15) that is adapted to be mounted to a fine filter section (12) for a dust extractor (1). The fine filter part kit (63) further comprises a filter lid (16) that is adapted to be mounted to a corresponding used fine filter part (15) to be replaced, already mounted to the fine filter section (12), and thereby seal an opening (28) of a particle containing space inside the used fine filter part (15) before removing the used fine filter part (15). In this way, release of particles contained in the particle containing space into the ambient air is prevented and a secure disposal of the used fine filter part (15) is enabled.

The invention provides a membrane filter assembly for analytical sample systems, and a sample system block assembly having a built-in membrane filter assembly. The filter assembly has a housing having recessed inner face having non-uniform depth, and a cover member having a plurality of concentric grooves and a radially oriented shallow groove crossing the concentric grooves, wherein the grooves each have wider top than the bottom.
