Patent ID: 7201845

Claim:
A system for filtering particles out of a fluid under transfer, the system comprising: a) a duct arranged to allow the fluid to pass therethrough, wherein an inside of the duct includes a first stationary rail and a second stationary rail; b) a filter frame including one or more filter components retained therein, wherein the filter frame includes a first channel arranged for slidable movement on the first stationary rail of the duct and a second channel arranged for slidable movement on the second stationary rail of the duct, and wherein the first stationary rail and the second stationary rail are arranged such that when the filter frame is positioned within the duct, the fluid passes through the one or more filter components; and c) a drive mechanism and a linkage arranged to coupled the drive mechanism to the filter frame, wherein the drive mechanism and the linkage move the filter frame into and out of the duct upon actuation of the drive mechanism, wherein the duct includes means to establish a sealing fit between the inside of the duct and the filter frame such that the filter frame moves into and out of the duct without halting the transfer of fluid through the duct.
