Abstract: Provided is an air or gas cleaning blower with a spiral separation chamber. An impeller draws in particulate-pervaded air or gas and imposes a centrifugal force that accelerates the particulate-pervaded air or gas outwards in the chamber.

The impeller pushes the separated particulates and cleaned air or gas further down the chamber with the particulates ejecting out a first outlet about the outer chamber wall and the cleaned air or gas circulating around the first outlet, moving further down the chamber, and ejecting out a second outlet.

Abstract: Methods using vane electrostatic precipitators collect charged and uncharged particles with vane assemblies that are physically arranged to reduce the air flow rate to at or below 1.0 ft/sec (0.305 m/sec).
