Abstract: An air cleaner assembly comprises a housing and a filter element. The housing comprises a first housing end and a second housing end. The second housing end of the housing defines an opening of the housing for fluid flow. The filter element is configured to be received through the first housing end of the housing. The filter element comprises a filter media and a closed endplate. The filter media comprises a first media end and a second media end. The second media end of the filter media defines an opening of the filter element for fluid flow. The closed endplate is positioned along the first media end of the filter media and comprises a wall with an axially inner surface and an axially outer surface. The axially outer surface is exposed to an area outside of the housing and closes off the first housing end of the housing when the filter element is positioned within the housing.

Abstract: A dry material transfer pump comprises an outer tube including an outer tube channel having an upstream end that is axially aligned with a downstream end thereof, and a plenum portion having a cross-sectional width that is larger than a cross-sectional width of the outer tube channel. A pressurized gas inlet is defined through the outer tube and is in fluid communication with the plenum portion. An inner tube is disposed annularly within the outer tube channel and defines an inner tube channel configured to receive particulate matter. At least one opening is defined radially through a wall of the inner tube and fluidly couples the plenum portion to the inner tube channel to allow the pressurized gas to flow from the plenum portion into the inner tube channel and create suction within the inner tube channel for drawing the particulate matter through the inner tube channel.
