An air filter system for use as original equipment or conventional filter replacement in a building ventilation system includes multiple helical particle separator elements in a parallel array, each element configured to remove particles from a respective portion of contaminated inflowing air. The outflows from the separator elements are combined into a common clean air outflow which is delivered to the building ventilation system. A common waste receptable collects particles removed by the separator elements and is cooperatively connected to a scavenger air system that draws air through the array and the receptable and relocates them to a desired location. The separator element array may be housed in a filter system containing the main system fan arrangement that is configured to draw or force the airflow through the multiple particle separators.

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 combustion gas supply system and method includes: a cyclonic air filter (or separator), a blower having an inlet and an outlet, and a combustible gas inlet, wherein the cyclonic air filter, the blower, and the combustible gas inlet are in fluid communication.

An appliance comprising an air flow path extending from an air inlet, by which water and air are introduced to the appliance, to an air outlet. A water separator is positioned in the air flow path, which, when in operation, separates the water from the air. A water storage chamber is in fluid flow communication with the water separator, which stores the water separated from the air. The appliance also comprises an automatic closure member movable between an open position and a closed position. When the automatic closure member is in the open position, the water storage chamber is in fluid flow communication with the water separator; when in the closed position, the water storage chamber is isolated from the water separator. The automatic closure member moves from the open position to the closed position when the pressure in the water separator increases above a predetermined level.

A system for aspirating a pre-cleaner of a work vehicle may include a fluid conduit in flow communication with an outlet port of the pre-cleaner for receiving an aspirated airflow from the pre-cleaner. The system may also include a double-walled flow pipe having an inner tube that receives a primary fluid flow of the work vehicle. The double-walled flow pipe may also include an outer tube surrounding the inner tube such that an annular passage is defined between the inner and outer tubes. The annular passage may be in flow communication with the fluid conduit. When a vacuum is applied to the annular passage, the aspirated airflow may be drawn through the fluid conduit from the pre-cleaner and directed to the annular passage. The aspirated airflow flows through the annular passage as the primary fluid flow is being directed through the inner tube.

A multiuse home station includes an autonomous surface cleaning apparatus docking station, an autonomous surface cleaning apparatus charging station, and a room air cleaner unit, wherein the room air unit uses a portion of the autonomous surface cleaning apparatus docking station.
