  • Tangential air cleaner with coiled filter cartridge
    Patent number: 11260404
    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.

  • Apparatus and method to clean particle loaded fluid using low energy multi-flow splitter technology requiring no filter media
    Patent number: 11253804
    Abstract: The present invention relates to an apparatus and a method of cleaning particle loaded “dirty” air using a multi flow-splitter technology in combination with at least one cyclone system which requires minimal energy to operate due to low pressure drops used to generate the fluid flows whilst allowing to exert high centrifugal or G-Force on the infeed fluid stream. This further allows to operate the particle removal process such that conventional additional filter media become optional, such that the technology may operate a significantly reduced or even without the need for maintenance and/or repair. Low internal air turbulence ensures a very high separation efficiency. Optionally adding additional explosion safe low-energy down-stream filtration stages with variable speed system fan provides optimal operational performance and operational flexibility.

  • Cyclonic dust filter device
    Patent number: 11253874
    Abstract: A cyclonic dust filter device comprises a trunk, at least one first retaining wall, and at least one second retaining wall. The trunk comprises a channel, an air inlet end and an air outlet end disposed at two ends of the channel, and a dust filter hole communicating with the channel. The first and second retaining walls are respectively disposed correspondingly to the dust filter hole. When a dust-containing airflow to-be-filtered enters the channel from the air inlet end, the dust-containing airflow forms a centrifugal airflow that contains the dust and is thrown out of the channel at a position of the dust filter hole. The first and second retaining walls are respectively disposed on a traveling path of the centrifugal airflow, so that the centrifugal airflow sequentially strikes the first and second retaining walls to change the traveling direction and then discharges dust free clean air.
