The present disclosure relates to a vacuum cleaner for separating and collecting dust and other contaminants by using a multi-cyclone and a mesh filter, including a cleaning unit for sweeping dust and foreign materials attached to the mesh filter along an outer circumferential surface of the mesh filter, and a rotation unit coupled to the cleaning unit for rotating the cleaning unit relative to the mesh filter, whereby the cleaning unit can clean a surface of the filter automatically or manually during an operation of the cleaner, so that the filter surface can be kept clean, and a load on a fan unit caused due to foreign materials or dust can be reduced.

A filtration device efficiently sizes removal of unnecessary substances adhering to and deposited on a filter medium of a filter element during filtration and backwashing (cleaning) from target (non-filtered) substances. The filter element captures substances in a fluid on one surface of a filter medium. The captured substances are separated from the filter medium during backwashing. A brush moves relative to the one surface of the filter medium and assists in separating the captured substances and sifting during the relative movement. The backwashing starts when a differential pressure between both surfaces of the filter medium exceeds a predetermined value, or the like while performing the filtration, and returns to filtration after the differential pressure is eliminated or after a predetermined time elapses. The brush sifts the unnecessary substances from the captured substances and passes the removal to the other surface side during the filtration.

A system for cleaning a filter mounted over an intake opening of an air handling unit. A conduit is secured to an elevated location of the unit and includes a plurality of spaced nozzles arrayed against the filter. A supply tube connects to the conduit for supplying a pressurized fluid through the nozzles in order to clear debris from an exterior of the mounted filter. The pressurized fluid includes either of a liquid (typically water) or a compressed air provided from any of a source or a supply reservoir. A pump is incorporated into the supply tube for pressurizing the fluid. A filter incorporated into the supply tube filters the pressurized fluid prior to delivery to spray issuing conduit. A processor/controller is provided in combination with an arrangement of control valves for providing timed sequenced washing of the filters. A collection basin is provided for recycling used liquid for re-delivery and re-use through the spray delivery conduits.

A filter assembly for a gas turbine system includes a filter element configured to remove entrained particles from air which passes through the filter element in a first direction toward a central air passageway. A motion generator arranged to rotate the filter element about a longitudinal axis extending in an airflow direction of the air passageway to cause particles accumulated on the filter element to fall downwardly away from the filter element due to gravity.

A filtration system includes a rotary drum and a media holding band that is configured to hold a filtration media on an outer surface of the rotary drum. The media holding band includes a strap and a connector. The strap includes a first end and a second end opposite the first end. The connector is configured to secure the first end of the strap relative to the second end of the strap.

A cleaning mechanism, a cleaning device, and an air conditioner are disclosed. The cleaning mechanism is configured to remove dust of an member object to be cleaned, and includes a dust suction member and a switch member. The dust suction member is movable in a reciprocating manner with respect to a surface to be cleaned of the object, and is provided with at least two separate dust suction chambers each having a dust suction port. In an extension direction of the dust suction chambers, a projected length of the dust suction port on the surface to be cleaned is smaller than the length of the surface to be cleaned. Each of the dust suction chambers is configured to communicate with a fan, and the switch member selectively communicates the fan with one of the dust suction chambers.
