Abstract

A filter system can include a replaceable filter cartridge having a spinner element structured to swirl a mixed flow of compressible fluid and oil, as well as an end cap used to enclose an open interior of a filter media of the filter cartridge. The filter cartridge can be configured to interface with and be supported by a mesh holder. A housing can be attached over the filter cartridge to enclose the system and create a flow path for a mixed flow of compressible fluid and oil. The replaceable filter cartridge can be constructed of materials suitable for disposal in a waste incineration process. The mesh holder can be inserted on a combo-block and secured in place by a compression fitting. A stand pipe can extend into the interior of the filter media and be coupled with a central passage of the mesh holder.
