Abstract: Filtration systems having a tangential air cleaner having a coiled media filter element and a cyclonic pre-cleaner are described. An outer wall of the filter element acts as a pre-cleaner sleeve of the housing to generate a cyclonic flow of the intake air prior to the intake air being filtered by the filter element. The housing cover includes geometry that redirects the cyclonic low from a tangential path to an axial, straight-through flow directed through an inlet flow face of the filter element. Various embodiments of such filtration systems offer increased filter performance and capacity compared to similarly sized cylindrical pleated filter elements having a radial flow filtering path.

Abstract: An air cleaner includes a base member including a base wall extending substantially horizontally, and a cover member attached to an upper side of the base wall to jointly define a filter chamber for receiving a filter element therein. The air cleaner further includes a passage member communicating with the filter chamber and incorporated with a plurality of air ejection pipes each surrounded by an annular air inlet passage fitted with guide vanes for rotating the air flow, and a case member defining separation chambers for separating dust from the rotating air flow. The passage member is interposed between the cover member and the case member.

Abstract: The present invention relates to 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 at a first end and the cap at a second end. The filter media assembly also including a first filter media extending across a primary air flow path and a second filter media extending across a secondary air flow path. The air filtration assembly then includes a blocking mechanism and an actuation assembly being configured to work together so as to selectively open or close the secondary air flow path so as to alternate the degree of filtration passing through the filter media based on the degree of desired filtration.

Abstract: A centrifugal air filter for an automotive system includes a plurality of single separators for setting an air flow passing therethrough in a turbulent motion and a separation area surrounding the plurality of single separators. The separation area receives particles from the air flow due to the centrifugal forces. A filter housing portion is located below a predefined or operation position for receiving particles from the air flow due to gravity, and an intake pipe is connected by an extraction line to a connecting pipe emerging on a filter housing and opening into the filter housing portion.

Abstract: A breather device and a snow removal machine having the breather device have a casing into which blowby gas of an engine flows, an air suction port for letting out gas from the inside of the casing, and a gas-liquid separation mechanism for separating moisture contained in the blowby gas. The gas-liquid separation mechanism separates an inlet, which allows the blowby gas to flow in, and the air suction port by a predetermined distance, and has the air suction port positioned above a liquid path through which the moisture flows. A gas path allows the blowby gas to flow from the inlet to the air suction port without passing through an air cleaner element.
