摘要： A compressor system includes a compression module having an inlet for receiving air; and a filter housing in fluid communication with the compression module. The filter housing is constructed to house a filter, the filter having a sealing feature disposed at a first end of the filter and having an engagement feature disposed at a second end of the filter opposite the first end. The filter housing includes a trap door constructed to contact the engagement feature, and constructed to drive the engagement feature in a direction parallel to an axis of the filter toward the sealing feature and urge the sealing feature into sealing engagement with the filter housing.

摘要： Apparatuses, systems and methods are disclosed including apparatus for a ventilation system for supplying air to a crankcase of an internal combustion engine. The apparatus can optionally include a housing, an air filter, a lid and a pressure relief valve. The housing can form a cavity and having an inlet and an outlet therein. The inlet communicates with the cavity and is offset from a centerline axis of the housing. The air filter can be received by the cavity. An outer circumference of the air filter can be oriented at an angle that is substantially tangent to the inlet. The lid can be attachable to and removable from the housing for selectively accessing the air filter. The pressure relief valve coupled to the housing and in fluid communication with the cavity.

摘要： System and method for removing molecular contaminants from an air stream are disclosed. The system includes first, second and third filter. The first filter removes organic contaminants from an air stream passing through the first filter. The second filter is downstream of the first filter, is physically and chemically exchangeable with the first filter and removes organic contaminants from the air stream output of the first filter. The third filter, downstream of the second filter, is not exchangeable with the first filter or the second filter. The first position filter can be replaced by the second filter in the second position when the first filter in the first position becomes depleted as detected. A new filter in the second filter position is inserted. Replacing the depleted first filter with the second downstream filter reduces costs and waste while inserting the new filter in the second position ensures removing organic contaminants.

摘要： Air cleaner assemblies, related methods, components therefor, and features thereof are described. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. In some examples, a filter cartridge for an air cleaner includes a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends and defining an outer perimeter with opposite straight sides and a first curved end. The filter cartridge can include a seal arrangement circumscribing the media pack outer perimeter, wherein a portion of the seal arrangement extends beyond a first plane defined by the media pack outlet flow end and a portion of the seal arrangement is disposed between the first plane and a second plane defined by the media pack inlet flow end, wherein the seal arrangement is aligned along a third plane disposed at an oblique angle to the first and second planes.

摘要： A filtering device for removing particles from a fluid of a patient is provided. The filtering device being implantable in the patient's body and comprising a cassette comprising a revolving member, said revolving member having at least two segments each holding a respective filter. The device further comprises a tube forming a fluid passageway through one of the filters in said cassette, wherein the cassette is adapted to, upon revolution of the revolving cylinder, change the filter positioned in the fluid passageway from a first one of said filters to a second one of said filters, thereby allowing particles present on the first filter to be moved away from the fluid passageway, while at the same time changing the filter positioned in the fluid passageway.

摘要： An air cleaner includes a case, an air inlet, an air outlet, a grill covering the air inlet to filter airborne oil droplets, a fan to suction air through the air inlet and discharge air out of the air outlet, a roll filter provided between the grill and the fan to filter oil mist, and a filter roller to cut the roll filter. The roll filter includes a roller and a filter sheet wound around the roller, and the filter sheet may be unwound to extend behind the grill. When the filter sheet becomes dirty, the roll filter is further unwound so that a clean section is provided behind the grill, and the filter cutter may cut off the dirty section. During cutting, a clamp holds down the filter sheet. The case includes a slit through which the dirty section of the filter sheet passes for discarding.

摘要： A filter device for filtering particles from an air stream has an inlet channel through which the air to be purified flows, at least one filter element through which the air can flow and which is interchangeably held in a flow channel, and an outlet channel through which the purified air flows, an insertion chamber which can be closed by a door and from which a filter element can be fed to the flow channel, and an output chamber closable by a closure element, into which a filter element is feedable from the flow channel. The closure element of the output chamber is locked in the closed position via a locking mechanism when the door on the insertion chamber is opened and the output chamber and the insertion chamber are connected to the same flow channel.
