Patent ID: 6951147

Claim:
An impact particle collector for separating particulates from a gaseous fluid in which the particulates are entrained, comprising: (a) a prime mover having a drive shaft that is drivingly rotated; (b) an impeller that is mechanically coupled to the drive shaft and rotated thereby, the impeller comprising a base plate and a plurality of vanes disposed on an upper surface of the base plate, such that a ratio of vane height to base plate diameter is in the range of about 0.01 to about 0.2; and (c) a housing for the impeller, said housing defining a fluid passage for conveying the gaseous fluid in which the particulates are entrained to the impeller, such that when the impeller is rotated by the prime mover, the gaseous fluid is drawn into the housing so that the particulates entrained in the gaseous fluid impact upon the impeller, being thereby separated from the gaseous fluid when impacted by the vanes of the impeller.
