ABSTRACT:
A device for separating and filtering particles in a flow of contaminated fluid, the device including a casing having an inlet duct fitted with a cyclone separator designed to concentrate centrifugally particles in the inlet flow towards the periphery of the flow, a tubular element mounted in the casing with the upstream end of the element adjacent the inlet duct and having a diameter smaller than the inlet duct so that the substantially clean fluid from the cyclone separator flows into a central flow path within the tubular element and the contaminated fluid from the separator flows into a peripheral flow path between the tubular element and the casing, and a filter mounted in the casing adjacent an outlet duct so that the clean fluid in the central flow path passes through a central passage of the filter to the outlet duct and the contaminated fluid in the peripheral flow path is filtered by the filter to form a filtered flow which mixes with the clean fluid in the central passage whereby the fluid flow rate in the outlet duct is the same as in the inlet duct.
