Patent ID: 8043412

Claim:
A portable, high air volume electrostatic precipitator comprising: a) an air stream passage having an inlet end and outlet ends and upper and lower walls; b) a fan operative to draw air into said passage at the inlet end and out through said outlet end at up to the velocity that will produce turbulence in the air stream passing therethrough, said fan having a portable power source associated therewith; c) an ionization wire located in said air passage near the inlet end, said ionization wire being positioned so that its length is transverse to the direction of the flow of air in said passage; d) a charged plate operatively connected to and spaced apart downstream from said wire, said plate being adjacent said upper wall; e) a collection electrode located below said upper plate adjacent said lower wall; f) a collection medium positioned adjacent and above said collection electrode and, g) a portable ionization power source operatively connected to said wire, plate, and electrode to create one or more electrostatic fields having the same or different potential levels that are capable of ionizing analytes in said air whereby ionizable analytes in said air are electrostatically precipitated on or into said collection medium.
