Abstract
A compressor driven by a motor delivers air under pressure to a plurality of paint spray guns. An air circulation fan is incorporated with the motor to cool the apparatus during operation. The compressor shaft includes bearings on each end and the bearing on the lower end is physically separated from the lower end of the compressor to prevent oil contamination of the air being discharged. A pump is associated with the separated bearing which delivers oil to lubricate the bearing when the compressor is in operation.
