The technology disclosed herein relates to a tank vent having a housing and a pleated, vapor-permeable microporous membrane. The housing defines a first vapor passageway configured for direct communication with a tank interior and a second vapor passageway configured for direct communication with the atmosphere. The housing also defines a tank mounting surface is mountable to a tank housing and a media mounting surface. The microporous membrane is sealed to the media mounting surface and defines a tubular structure such that the first vapor passageway and the second vapor passageway are in communication through the microporous membrane. Other embodiments including methods are also disclosed.

An air box and methods are provided for communicating an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The air box is comprised of a housing that supports the air filter within an interior of the housing. A mount portion within the housing fixedly receives a base of the air filter. Multiple air inlets couple with corresponding air inlet ports of the vehicle to direct the airstream into the air box. A duct directs the airstream from the multiple air inlets to the interior of the housing and to the air filter. An opening into the housing exposes at least one surface of an electronic control unit (ECU) to the airstream for cooling of the ECU. A conduit communicates the airstream from an interior of the air filter to the air intake duct of the internal combustion engine.

A filter assembly for use with a surgical suction tool for removing fluid and debris from a surgical site includes a conical filter element with a plurality of orifice arrays spaced along the length of the conical body with successively decreasing orifice diameters. The filter element includes an annular flange at the mouth of the filter element that is clamped between a container and a cap. The container includes conically tapered wall to define a radial space between the container and the filter element to permit fluid flow around the filter element and through the container to an outlet tube fitting. A cap covers the mouth of the container with a threaded interface defined between the cap and the container. The threaded interface includes a dual pitch triple lead thread with a coarse lead-in pitch and a fine trailing pitch.

A filter assembly includes a filter head and filter cartridge. The filter cartridge includes a housing and element. The housing includes a can with an open mouth. An interface ring is secured to the can adjacent to the open mouth. The outer ring surface is against the inner wall of the can. The ring wall is angled between the first and second ends greater than one degree and less than 6 degrees. Methods of filtering and making the housing are provided.

In one embodiment, a material sorting system comprises: a suction gripper assembly, the suction gripper comprising: a body assembly that includes: an internal airflow passage configured to communicate an airflow between an airflow application port positioned at a first end of the body assembly and a gripping port positioned at the opposing second end of the body assembly; a cup fitting attached to the gripping port; a suction cup secured to the cup fitting; an attachable filer inserted into the suction cup and fastened to the cup fitting; and a mounting assembly, wherein the mounting assembly includes one or more mounting points for pivotally attaching the suction gripper assembly to a sorting robot of the material sorting system.

The air filter device includes a main member, a conduit member, a sealing piece, a pressurizing piece, a filter element, and a cap. The conduit member, sealing piece, pressurizing piece, and filter element are sequentially stacked in the main member. The conduit member provides a spiral duct with a second inlet and a second outlet. The second inlet is conducted to an outlet opening of the pressurizing piece. The second outlet is conducted to a plug extended from a bottom side of the main member. The cap is fastened to the main member with airflow paths between the cap and main member. The main member may be joined to the inlet terminal of any air compressor. External air is drawn into the air compressor through the filter element, pressuring element, conduit member, and the plug so as to achieve smooth, steady, and quiet air intake.

An air filter, an air filter assembly, and method of installing the air filter into a housing of the air filter assembly are provided. The air filter includes an attachment portion and a lock tab. The lock tab is carried by and resiliently moveable relative to the attachment portion. The lock tab is located radially outward from the attachment portion and movable circumferentially about a central axis of the air filter. Another feature relates to using an end stop in a housing as a catch. Yet another feature relates to using a perforated end cap and capping such perforations with a housing seal.

The oil air separator system is designed to stop oil contaminated air from entering the intake manifold. All engines have a vacuum hose from the valve cover or valley pan connected to the intake manifold. The device serves to evacuate blow by from the engine. The contaminated air (with oil vapors) is effectively removed. This prevents oil deposits from being realized inside the intake manifold and on the spark plugs. By removing the dirty air, the engine can breathe clean air. The container can hold the oil and water while the filter inside keeps the air clean reducing pollution.
