Systems and methods for methods and systems for reducing contaminants in a feed stream are disclosed. Prior to reaching or upstream from one or more compressors, solid foulant is filtered from a feed stream. The compressor may further filter the feed stream. By reducing the solid foulant entering the one or more compressors, performance and life span of the one or more compressors also can be increased.

A method for removing particles from a bodily fluid in a patient with a filtering device, the filtering device being implantable in the patient's body and the method comprising the steps: pass bodily fluid of the patient through a tube forming a main fluid, filtering the bodily fluid passing through said main fluid passageway with a filter connected to the tube, collecting particles in the bodily fluid to be removed passing through the tube, and cleaning the filter with a filter cleaning device by removing particles collected by the filter out of the fluid passageway.

A canister vacuum cleaner has a cyclone bin assembly that has a cyclone chamber and a dirt collection chamber. The cyclone chamber has an openable upper end and an openable lower end. The dirt collection chamber is rearward of the cyclone chamber and only partially surrounds the cyclone chamber. The suction motor is rearward of the dirt collection chamber. A pre-motor filter is provided below the cyclone chamber and the cyclone air outlet has an outlet axis that intersects the pre-motor filter. Air travels upwardly from the pre-motor filter to a suction motor inlet.
