Introduction
The Ingersoll Rand 47545144001 54509427 Air/Oil Separator Element is a maintenance-focused component for compatible oil-injected rotary screw compressor systems. The 54509427 reference is consistently identified as an Ingersoll Rand air/oil separator, while MANN-FILTER independently cross-references the number to LE 38 022.
Air/oil separation is essential in an oil-injected rotary screw compressor. During compression, lubricating oil becomes entrained in the compressed-air stream. The separator element coalesces fine oil aerosols so that the oil can be recovered and returned to the lubrication circuit rather than being discharged with the compressed air. This helps control oil consumption and supports cleaner downstream air.
The 54509427 element is associated with a relatively large separator configuration. CAPS identifies it as an 18-inch-tank separator element, while other published technical references place its height at approximately 432–433 mm and outer diameter around 375 mm. Because replacement suppliers publish somewhat different dimensional values, these figures should be treated as reference data rather than a substitute for the applicable OEM drawing or parts list.
The relationship between 47545144001 and 54509427 should also be interpreted carefully. The first number identifies an Ingersoll Rand maintenance reference, whereas 54509427 identifies the individual separator element. Available sources do not establish a complete bill of materials proving that 54509427 is supplied in every 47545144001 package. Buyers should therefore verify the applicable package contents before assuming direct inclusion.
From a maintenance perspective, separator condition has a direct effect on compressor performance. A restricted or deteriorated element can increase pressure drop and may contribute to excessive oil carryover. Replacing the separator according to the machine's maintenance schedule helps preserve separation performance and maintain the intended compressed-air quality.
The established cross-reference to MANN-FILTER LE 38 022 can also support procurement research when OEM availability is limited. However, cross-reference information should be treated as a technical starting point rather than automatic proof of interchangeability. Separator dimensions, sealing configuration, flow direction, and vessel design must all match the application.
For industrial operators, selecting the correct 54509427 element provides a practical way to support oil recovery, compressor efficiency, and downstream air quality. Final selection should always be based on the compressor model, serial number, original separator reference, and current parts documentation.
