A compressor system can include a lubricant injection system useful to supply lubricant to an airend. The compressor system can include a variable lubricant flow valve which can be regulated by a controller on the basis of operating conditions of the compressor system. In one form the compressor system also includes an oil separator and/or an oil cooler with or without a thermal control valve. The controller can have one or more modes of operation, including a mode in which the controller regulates the flow of lubricant to the airend to increase an internal flow area of the valve when the airend is operated at an unloaded or loaded condition. In some forms the controller can regulate the lubricant flow valve and/or the thermal control valve and/or the lubricant cooler.

Airend having a lubricant flow valve and controller

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.

A separation tank useful to separate a compressed gas from a byproduct of compression (such as a lubricant/coolant used in the compression process) can include one or more baffles. The baffles used in the separation tank can include a number of passages to permit a flow of compressed gas to pass. The passages can include a louver to assists in directing the flow and/or assist in further separation of the compressed gas from the lubricant/coolant. The louvers can appear on one side of the baffle, and in one form are located solely on the downstream side of the baffle. The baffle can include a relief for liquid leveling within the tank. Any number of approaches can be used to make the baffle, including cutting and/or stamping.
