Ingersoll Rand 47556402001 23545841 Water-Cooled Preventive Maintenance Kit with Modification

Introduction

The Ingersoll Rand 47556402001 23545841 Water-Cooled Preventive Maintenance Kit with Modification combination covers the air/oil-separation portion of the modified 8,000-hour major-service program for the R90–110 I platform. The published service data identifies 47556402001 as the water-cooled package with MOD and specifies one 23545841 separator-tank element.

In an oil-injected rotary screw compressor, compressed air leaving the compression process contains entrained lubricant. The separator element performs the important coalescing function of removing this oil from the air stream before the air proceeds downstream.

23545841 is identified by OEM-oriented sources as an 18-inch separator-tank element. Source Atlantic describes it as an OEM separator for rotary-screw compressor oil/air systems, while another supplier describes it as a drop-in separator installed inside the sump tank.

The relationship between the two requested references is direct. The R90–110 I service table places 23545841, quantity one, within 47556402001. The same modified package includes 23429822, 23424922, 23497001, 23531577, 47552954001, 47553881001, 47555464001, and 39218193.

The modified status is important for maintenance planning, but it does not change every recurring component. The published list keeps 23545841 unchanged while modifying the inlet-valve service reference from 47553880001 to 47553881001.

Separator condition directly affects oil carryover and pressure drop. A loaded or deteriorated separator can increase differential pressure, while a damaged or incorrectly installed element can allow excessive oil to remain in the compressed-air stream.

Published technical data for 23545841 identifies borosilicate micro-glass-fibre media, approximately 3 µm, with approximately 1,596 m³/h permissible flow and 5 bar collapse pressure. These figures are useful for product identification, while current machine-specific OEM documentation should remain the final engineering reference.

During replacement, technicians should inspect the separator vessel, sealing surfaces, oil-return arrangement, and associated connections. A new separator cannot compensate for a damaged seal, restricted oil-return path, or defective vessel interface.

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

23545841 is used on a broader group of R/RS compressor configurations. One OEM-oriented listing identifies RS90ie, RS110ie, RS132i, RS132ie, RS160i, and RS160ie applications. This broader use makes compressor model, serial number, and separator architecture important when validating fitment.

For maintenance planners, 47556402001 should be distinguished from the standard water-cooled 8,000-hour package 47555465001. The separator reference may be shared, but the overall kit differs because of the MOD configuration.

For purchasing teams, retaining the full pair of references is useful: 47556402001 identifies the modified 8,000-hour water-cooled service event, while 23545841 identifies the specific separator element.

Replacement should follow the applicable Ingersoll Rand service procedure, including correct seating, sealing, oil-return inspection, and post-service checks. The separator vessel and related components should be inspected while the system is accessible.

Aftermarket cross-reference products exist for 23545841, but these should be evaluated against the required dimensions, efficiency, flow capacity, sealing arrangement, and compressor application rather than accepted solely based on a cross-reference number.

Exact current package dimensions, package weight, complete revision-specific kit contents, and all OEM separator engineering tolerances were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.

For industrial compressor operators and maintenance professionals, 47556402001 and 23545841 provide a clear reference for separator service within the modified 8,000-hour water-cooled R90–110 I maintenance program. Correct configuration matching and careful separator installation can help control oil carryover, maintain compressed-air quality, and support reliable compressor operation.
