An air filter has a filter housing with inlet opening, outlet opening, and service opening. A first filter element and a second filter element are arranged inside the filter housing between inlet opening and outlet opening. The first filter element is arranged in a mounting frame. The first and second filter elements can be flowed through serially in one or more operating states of the air filter. The mounting frame is insertable through the service opening into the filter housing in a joining direction and removable from the filter housing opposite to the joining direction. The second filter element has a wedge stop. A clamping wedge arranged at the mounting frame, upon insertion of the mounting frame into the filter housing, contacts the wedge stop of the second filter element and clamps the second filter element at the filter housing in a clamping direction transversely to the joining direction.

Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow-establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicle, with or without using flow-establishing devices.

A taking up/receiving system (100) and a process for taking up/receiving of gas from a medical apparatus (1) are provided. The taking up/receiving system includes a feed line (6), a discharge line (8), a filter unit (4) with a filter and at least one buffer storage device. The feed line establishes a fluid connection between the medical apparatus and the filter unit. The discharge line establishes a fluid connection between the filter unit and a fluid taking up/receiving unit (7). The gas is discharged from the medical apparatus and is passed through the feed line to the filter unit and from there through the discharge line to the fluid taking up/receiving unit. The filter filters at least one gas component out of the gas that is passed through the filter unit. The one or more buffer storage device absorbs and again discharges gas from time to time.

A filter device separating impurities from a gas, including a filter housing having a lid and a pot; the lid having an inlet and an outlet; a filter element in the pot with a top cap and a bottom cap with a filter cartridge therebetween; the top cap has an inlet duct connected to the lid inlet so that the gas to be purified is passed through the inlet duct to the filter cartridge; a space is between the lid and the top cap which is connected to the outlet of the lid; a switching element to be installed rotatably in the lid and rotatable between an off-position in which the inlet port or the outlet port connects to respectively the inlet or outlet of the lid, and a twisted position, in which the entrance of the inlet duct of the top cap can connect to the lid inlet.

The present invention relates to a system for treating gaseous hydrogen, comprising an inlet (10a) for supplying gaseous hydrogen, a drying unit (30) with an active drying material for removing moisture from the supplied hydrogen, an adsorption unit (50) with an active adsorption material for adsorbing impurities from the dried hydrogen, and an outlet (10b) for drawing off treated hydrogen. According to the invention, the mass ratio between the active drying material and the active adsorption material is in the range of 1.5:1 to 50:1. The invention further relates to a plant comprising such a system for providing compressed treated gaseous hydrogen and a method for treating gaseous hydrogen.

The invention describes a filter element for an oil separator of a crankcase ventilation system in which a filter element is configured to separate oil from fluid and that has a covering surface extending parallel to a direction of flow, together with at least one cover element covering surface in at least some regions. An oil separator is taught having the filter element with at least one pressure control valve controlling crankcase pressure and has a valve closing body that operates in conjunction with a valve seat.

A vacuum cleaning device comprises a housing having a dirty air inlet and a clean air outlet. An airflow path extends between the dirty air inlet and the clean air outlet. A dust container is mounted to the housing wherein the airflow path goes through the dust container. A motor fan assembly is mounted in the housing and is configured to create an air flow along the airflow path in a blow mode and a suction mode. A controller is configured to control the motor fan assembly in the blow mode and the suction mode. The controller is configured to control the motor fan assembly to pulse the motor fan assembly at first fan speed when in the blow mode.

The Smart Accumulator Fluid Scrubbing System includes a drying mechanism and filtration system with liquid level control all in one housing to protect compressors or compressor systems from moisture, contaminants, and liquid ingestion. The Smart Accumulator is connected to the compressor or compressor systems inlet. The Smart Accumulator only allow dry, clean gas to enter the compressor and compressor system. The switch in conjunction with the heating elements and compressor circuits prevents the compressor from running, while heating elements boil off excess liquid. The Pressure equalizing port prevent compressor to start at high delta pressure and or reduces extremely high-pressure compressor or system operation that may be detrimental to mechanical failure.

A multi-modal multi-media air filtration system which can include: a base having one or more connection features and a filter media assembly, the filter media assembly being configured to attach to the base portion at a first end. The filter media assembly can then also include a first filter media extending across a first air flow path and a second filter media extending across a second air flow path. The air filtration assembly can then also include an actuation assembly configured to selectively open or close one of the first air flow path or the second air flow path so as to alternate the degree of filtration passing through the filter media assembly based on the degree of filtration provided by the first or second filter media.
