Introduction
The Ingersoll Rand 47545144001 39911631 Oil Filter Element is a maintenance-focused filtration component for compatible industrial air compressor systems. The 39911631 reference is consistently catalogued as an Ingersoll Rand oil filter, while 47545144001 is associated with Ingersoll Rand preventive-maintenance service. Because available sources do not provide a complete bill of materials for 47545144001, the presence of 39911631 in the kit should be verified rather than assumed.
Oil filtration plays a central role in the reliability of a rotary screw compressor. Lubricating oil circulates through the compression and cooling system, and contamination can affect precision components over time. The 39911631 element is designed to remove particles and debris from circulating compressor oil before it returns to the compression process.
The application range of 39911631 is substantial. Published information identifies the filter with many Ingersoll Rand EP75 and EP100 rotary screw compressors, while additional HP, XP, HXP, EPE, and MH55 applications are documented by different sources. This broad usage makes accurate model and serial-number verification particularly important because similar compressor families can use different filter references.
Technical reference data further supports precise procurement. Oxfil lists a 121 mm outer diameter, 295 mm body height, 299.1 mm total height, UN 1-3/4 female-bottom thread, 25 bar working pressure, 54 bar burst pressure, 15 bar element collapse pressure, 12 µm inorganic microfiber media, and a 2.08 kg product net weight. These values are supplier-published specifications and should be verified against the current supplied component and application.
The 39911631 reference is also supported by independent filtration cross-reference information. MANN-FILTER identifies WH 1257 as its corresponding sales designation, while other cross-reference sources list Baldwin BT8874-MPG, Donaldson P171275, Fleetguard HF6586, and additional filter references. Such cross-references are useful for sourcing but should not replace an application-specific compatibility check.
For preventive maintenance teams, replacing the oil filter at the prescribed interval is a straightforward way to support clean lubricant circulation. Published service information for applicable compressor ranges recommends replacement every 2,000 operating hours or annually, although the actual interval should always follow the maintenance schedule for the specific machine.
When purchasing the Ingersoll Rand 47545144001 39911631 combination, it is important to distinguish the maintenance reference from the individual filter component. The 47545144001 number identifies the maintenance-service reference, whereas 39911631 identifies the oil filter element. Confirming the exact kit contents and machine fitment before purchase provides better parts traceability and helps prevent installation errors.
