Ingersoll Rand 47674732001 23545841 Preventive Maintenance Kit

Introduction

The Ingersoll Rand 47674732001 23545841 Preventive Maintenance Kit provides a defined reference for scheduled separator service on compatible R90–110 compressor equipment. 47674732001 is listed as a 4,000-hour preventive maintenance kit, while 23545841 is the associated separator-tank element in the published R90–110 I service configuration.

In an oil-injected rotary screw compressor, the compression process produces a mixture of compressed air and entrained lubricant. The air/oil separator is responsible for coalescing the suspended oil and returning separated lubricant to the appropriate circuit while allowing the compressed air to continue toward downstream cooling and treatment equipment.

The 23545841 reference is specifically identified as an 18-inch separator-tank element. An OEM-oriented supplier describes it as an Ingersoll Rand separator for an 18-inch tank, while other current parts references identify it as an air/oil separator element.

The relationship between the two requested references is direct. The R90–110 I maintenance table lists 47674732001 as the 4,000-hour preventive-maintenance package and specifies one 23545841 Element, Separator Tank in that package, together with the 23429822 air filter, 23424922 coolant filter, 23497001 pre-filter, and 39218193 motor grease.

Separator condition has a direct relationship with compressed-air cleanliness and compressor efficiency. As the element accumulates separated oil and contaminants, pressure drop can increase. A damaged or degraded element can also allow excessive oil carryover into the downstream air stream.

Published reference data for 23545841 identifies borosilicate micro-glass-fibre media at approximately 3 µm, a permissible flow of about 1,596 m³/h, out-to-in flow direction, and a collapse pressure of approximately 5 bar. These values are useful for reference, but current compressor-specific documentation should remain the final authority for engineering specifications.

The separator should be treated as a system component rather than an isolated filter. The separator vessel, oil-return arrangement, seals, connections, and associated pressure-control components should be inspected whenever the element is replaced.

Proper installation is particularly important. The replacement element must be correctly seated within the separator vessel, and sealing surfaces should be inspected for contamination or damage. Installation details should follow the applicable Ingersoll Rand service procedure.

Separator replacement is commonly performed as part of a broader service event. For compatible R90-series equipment, associated maintenance components can include the primary air filter, pre-filter, coolant filter, and motor grease. Servicing these components together helps maintain traceability and reduces the risk that an overlooked consumable will remain in service beyond its intended maintenance point.

The 23545841 reference is used beyond the R90–110 I platform. Current product data identifies it on RS90ie, RS110ie, RS132i, RS132ie, RS160i, and RS160ie applications, while other references also associate it with R-series separator systems. This broad usage is another reason to verify compressor model and serial number rather than assuming universal interchangeability.

Oil carryover should not automatically be attributed to the separator. Incorrect lubricant level, oil-return problems, operating conditions, damaged seals, or other separation-system faults can produce similar symptoms. A complete diagnostic assessment is appropriate when abnormal oil carryover is observed.

For purchasing teams, the 47674732001 kit reference and the 23545841 individual component number should be retained together in service records. This provides a direct link between the scheduled maintenance event and the specific separator element required for the documented configuration.

Third-party cross-reference information exists for 23545841, including HIFI FILTER OS578, WIX P08D341, and SF-FILTER SAO59994. Such data can assist sourcing, but cross-reference numbers should not be treated as automatic approval for substitution without confirming dimensions, filtration characteristics, flow capacity, seals, and compressor fitment.

For industrial maintenance teams, a separator replacement program should also include inspection of the separator-vessel interior, oil-return circuit, gaskets or seals, and associated piping. This helps identify conditions that could reduce separator life or create repeated oil-carryover problems.

Exact current Ingersoll Rand package dimensions, package weight, complete kit contents for every revision, and all separator engineering tolerances were not sufficiently verified from authoritative documentation. Those values are therefore intentionally not estimated.

For compressor operators and purchasing professionals, 47674732001 and 23545841 provide a clear reference for scheduled 4,000-hour separator maintenance on the documented R90–110 I configuration. Correct application matching and careful separator installation can help control oil carryover, maintain compressed-air quality, and support dependable compressor performance.

Technical Specifications

Published separator data provides approximately 447 mm height, 299 mm OD, 208.5 mm ID, 3 µm borosilicate micro-glass media, 1,596 m³/h permissible flow, and 5 bar collapse pressure.

Recommended Companion Models

These components are listed together with 23545841 in the R90–110 I preventive-maintenance program and address complementary air filtration, fluid filtration, intake pre-filtration, and motor-lubrication functions.
