Abstract
A filter for filtering particulates from a particulate-containing fluid stream passing through the filter, contains one or more flow plates, each of the flow plates having (a) one or more primary fluid flow passages; and (b) one or more particulates-collecting, eddy current-forming accumulation chambers communicating with the primary fluid flow passages; wherein the accumulation chambers are not situated in the primary fluid flow passages and, when the accumulation chambers contain particulates, the particulate-containing accumulation chambers do not impede fluid flow through the primary fluid flow passages.
