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 flow 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.

Systems are disclosed for separating and collecting liquid and particulate from a flowing gas stream. The systems may include a plurality of horizontally oriented helical separators positioned in a vessel between a gas stream inlet and a gas stream outlet. The helical separators form helical channels for the gas stream and may include an upstream conical portion. The vessel includes a first space upstream from the helical separators wherein the gas stream changes direction before entering the helical separators, such that the change in direction causes mechanical separation of liquids or solids from the gas stream. The vessel may also form a second space downstream from the helical separators for collecting liquid and particulate separated from the gas stream. The first and second spaces in the vessel may each include a drain which empties into a common sump, such that the first and second spaces are in fluid communication.

A compact dual stage cyclone separation assembly, an efficient dual stage cyclone separator, and a method for utilizing the same, comprising a lower pressure drop across the dual stage separators due to fewer particle-contaminated gas flow directional changes in the particle contaminated gas stream, and method for using same. The dual stage cyclone separator comprises a primary stage cyclone barrel and a second stage cyclone barrel, wherein the second stage cyclone barrel is coaxial with and concentric within the first cyclone separator, a solids extraction port, wherein said sidewall of said main body defines a solids extraction port opening located between said upper end and said lower end for discharging large particles from said cyclone body, and a small particle discharge opening, wherein the small particle discharge opening is located inside the lower end of the main body.

A process and apparatus of a gas-solids separator are provided in which a cap is disposed across an upstream end of swirl blades in a cyclonic separator to protect the blades from erosion by fast traveling solids.
