Abstract: Some embodiments of the disclosure are directed to an air/fluid filter device comprising a sheet of material initially configured in one or more planar sections, a plurality of organized air/fluid outlets arranged on the sheet and configured to allow the air/fluid to flow through the sheet, and a plurality of cyclonic compartments coupled to the sheet, each compartment comprising a cyclonic structure comprising at least one of a cone or a cylinder, including a tangential inlet, and a cyclonic outlet at the end of the cyclonic structure that is coupled to the sheet. In some embodiments, each tangential opening is in air/fluid communication with a respective incoming air/fluid side of the sheet, and each cyclonic outlet is coupled to a respective outlet of the sheet.

Abstract: An air filter comprising a housing, a plurality of cyclonic-element arrays and a plurality of individual airflow paths is disclosed herein. The housing includes a first side configured to be arranged or otherwise exposed to an upstream side of a first airflow, and a second side configured to be arranged or otherwise exposed to a downstream side of the first airflow. In some embodiments, the plurality of cyclonic-element arrays may be organized in a parallel or approximately parallel arrangement within and/or supported by the housing. Further, the plurality of individual airflow paths may correspond to the plurality individual of cyclone elements in each array life.

Abstract: Embodiments of the present disclosure are directed to cyclonic air filtering systems for removing fine particles from an air stream. In some embodiments, small diameter cyclonic separators/elements are used to remove fine particles from an airflow where a large number of such elements are assembled together in a compact arrangement. In some embodiments, an air filtration system is presented and can comprise a housing including a plurality of compartments, an air inlet side and an air outlet side. Such a system can further include a plurality of cyclonic filtering arrays each housed in a respective compartment and each comprising an assembly of a plurality of cyclonic elements configured to filter air of an airflow via centrifugal force (i.e., cyclonic separation). The system can include mating means configured such that most, and in some embodiments, all of the airflow flows only through the arrays.
