Ingersoll Rand 47555465001 23545841 Water-Cooled Preventive Maintenance Kit

Introduction

The Ingersoll Rand 47555465001 23545841 Water-Cooled Preventive Maintenance Kit combination covers the air/oil-separation portion of the 8,000-hour major-service program for the R90–110 I configuration. The service-parts listing identifies 47555465001 as the water-cooled preventive-maintenance package 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 critical coalescing function of removing this oil from the air stream and returning separated lubricant toward the appropriate oil circuit.

The 23545841 reference is clearly identified as an air/oil separator and as an 18-inch separator element. Source Atlantic describes it as an OEM separator element for rotary-screw compressor oil/air systems and identifies the separator length as 18 inches.

The direct relationship between the requested references is especially clear in the R90–110 I service data. Under 47555465001, the parts list specifies one 23545841 element together with the 23429822 air filter, 23424922 coolant filter, 23497001 pre-filter, 23531577 minimum-pressure-valve kit, 47552954001 temperature-sensing-valve kit, 47553880001 inlet-valve kit, 47555464001 water-cooler-seal kit, and 39218193 motor grease.

This shows that the 8,000-hour package is a comprehensive major-maintenance event rather than simply a filter replacement. Filtration, separation, pressure control, temperature control, inlet regulation, cooling, and motor lubrication are addressed together.

The separator's condition can have a direct effect on compressed-air quality and compressor efficiency. As the element becomes loaded or otherwise deteriorates, pressure drop can rise. Conversely, an incorrectly installed or damaged separator may allow excessive oil carryover downstream.

Published reference data for 23545841 describes borosilicate micro-glass-fibre media rated at approximately 3 µm, an out-in flow direction, permissible flow of approximately 1,596 m³/h, and collapse pressure of approximately 5 bar. These figures are useful for product identification, but the compressor-specific OEM documentation should remain the final authority.

Proper installation is important because the separator sits inside the separator vessel and depends on correct sealing and alignment. Before installation, technicians should inspect the vessel, sealing surfaces, oil-return arrangement, and associated connections for contamination, damage, or abnormal wear.

A separator problem should not automatically be assumed to be the cause of high oil carryover. Oil level, scavenge or oil-return problems, lubricant condition, pressure-control faults, operating conditions, and other system issues can produce similar symptoms. Troubleshooting should therefore consider the complete separation system.

The 23545841 reference is also used in broader Ingersoll Rand R/RS compressor applications. Current supplier data identifies applications including RS90ie, RS110ie, RS132i, RS132ie, RS160i, and RS160ie, while other sources associate it with R90i/R110i and related configurations. This makes model and serial-number verification essential even though the separator reference itself is widely used.

The separator should normally be considered together with the surrounding service components. When replacing it, technicians can inspect the separator vessel, seals, oil-return circuit, pressure-control components, and associated piping while the system is accessible. This can help identify conditions that might otherwise cause premature separator failure.

For maintenance planning, the 8,000-hour interval should also be distinguished from the R90–110 I 2,000-hour and 4,000-hour packages. The published service table identifies 47674733001 at 2,000 hours, 47674732001 at 4,000 hours, and 47555465001 at 8,000 hours for the relevant configuration.

For procurement teams, retaining both the complete kit number and the individual separator reference gives useful service traceability. This is particularly important where similar separator elements are used on different compressor families or where aftermarket cross-references are being evaluated.

Aftermarket equivalents for 23545841 include HIFI FILTER OS578, WIX P08D341, and SF-FILTER SAO59994. These references are explicitly described by the supplier as aftermarket alternatives rather than original Ingersoll Rand products. Substitution should therefore be evaluated against the compressor's required efficiency, dimensions, flow capacity, sealing arrangement, and current service documentation.

The exact current package dimensions, package weight, complete kit contents for every revision, and detailed OEM separator-media engineering characteristics were not sufficiently verified from authoritative documentation. These specifications are therefore intentionally not estimated.

For industrial compressor operators and maintenance professionals, 47555465001 and 23545841 provide a clear reference for the separator portion of the 8,000-hour water-cooled R90–110 maintenance program. Correct separator identification and careful installation can help control oil carryover, maintain compressed-air quality, and support dependable compressor performance.
