Method and apparatus for heating gases cooled by an aftercooler that receives hot gases from a compressor. The method includes the steps of directing at least a portion of said hot gases to means for bypassing the aftercooler, and using the bypass means to direct hot gases to a location that receives cooled gases from the aftercooler. The hot gases are used at the location to heat the cooled gases when ambient temperature is at or below freezing, and are used downstream from the aftercooler when moisture freezes in the aftercooler.

A shaft extension for attachment to a crankshaft of an electric motor driven air compressor to axially extend the crankshaft for engagement with an outboard rotational bearing. The electric motor driven air compressor includes a bearing plate, an inboard rotational bearing mounted on the bearing plate, the crankshaft projecting through both of the inboard rotational bearing and the bearing plate and terminating in a distal end disposed exterior of the bearing plate. The air compressor also includes an electric motor, the electric motor having a stator frame, a stator fixedly mounted within the stator frame, and a rotor fixedly mounted to the crankshaft for rotation therewith and disposed interior of the stator. The air compressor further includes the outboard rotational bearing disposed axially outboard of the stator frame, the stator, and the rotor. The shaft extension includes an extension member having an extended major axis and a minor axis extending substantially transverse to the extended major axis and a connection mechanism for connecting the extension member to the distal end of the crankshaft.

Apparatus for lubricating components in an air compressor having a crankcase for holding oil. The apparatus includes an oil pump located in the crankcase and oil, and a hollow plunger mechanically and hydraulically connected between the oil pump and an eccentric provided on a crankshaft of the air compressor. A filter for filtering the oil held in the crankcase is mounted on a block secured to an external surface of the crankcase. The block mounts the filter on the crankcase and in fluid communication with the pump such that filtered oil is directed to the hollow plunger from the pump after oil is directed into the pump from the filter and after oil is pumped from the crankcase and sent to the filter by the pump.

Air compressor bearing lubrication

A thermostatically controlled intercooler system for use with a multiple stage compressor to prevent the condensation of water from the compressed gas, such as air, within the system, whereby the temperature of a compressed gas entering a second compressor stage following the first compressor stage is controlled to a target temperature, ideally up to about 250.degree. F., as will not allow the partial pressure of the water vapor therein to exceed the saturation vapor pressure associated with and defined by the temperature achieved by cooling the air prior to the air entering the subsequent compression stage.
