Ingersoll Rand 47555208001 23545841 Air-Cooled Preventive Maintenance Kit

Introduction

The Ingersoll Rand 47555208001 23545841 Air-Cooled Preventive Maintenance Kit combination covers the air/oil-separation portion of the 8,000-hour air-cooled service program for the R90–110 I compressor configuration. The published maintenance table identifies 47555208001 as the 8,000-hour air-cooled package and lists one 23545841 separator-tank element within it.

In an oil-injected rotary screw compressor, the compression process produces compressed air containing suspended lubricant. The separator element performs the important coalescing function of removing that oil from the air stream before the air proceeds toward the cooling and downstream treatment system.

The 23545841 component is described as a drop-in separator that sits inside the sump tank. Its purpose is to remove oil from the airstream while supporting return of separated lubricant to the compressor oil circuit.

The requested part numbers have a direct maintenance relationship. The R90–110 I 8,000-hour air-cooled service listing includes 23429822 as the air filter, 23424922 as the coolant filter, 23497001 as the pre-filter, 23545841 as the separator, 23531577 as the minimum-pressure-valve kit, 47552954001 as the temperature-sensing-valve kit, 47553880001 as the inlet-valve kit, and 39218193 as motor grease.

This makes 47555208001 a major scheduled service event rather than a simple filter-replacement package. Separator replacement forms one part of a larger maintenance operation addressing filtration, pressure control, temperature control, intake control, and motor lubrication.

Separator condition has a direct relationship with both compressed-air cleanliness and compressor efficiency. As the element becomes loaded, pressure drop can increase. A compromised element can also allow excessive oil carryover into the downstream compressed-air system.

One OEM-oriented parts source recommends replacing 23545841 at approximately 8,000 operating hours or once per year, whichever comes first, for the listed RS90–RS160 applications. Actual replacement should follow the compressor's applicable service schedule and operating conditions.

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

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

The 23545841 reference is used across multiple R-Series configurations. Current parts data shows it for R90i/R90n/R110i/R110n, while separate sources identify RS90ie, RS110ie, RS132i/ie, and RS160i/ie applications. The exact compressor configuration therefore remains important when validating fitment.

The separator reference can also change with separator architecture. One current parts table shows 23545841 for single-stage R90i/R90n/R110i/R110n machines, while two-stage R90IE/R110IE machines use 23566938 instead. This is an important distinction for procurement and substitution.

For maintenance planning, 47555208001 should also be distinguished from the corresponding 8,000-hour water-cooled package 47555465001. The recurring separator reference may be shared, but the overall service package changes according to compressor cooling configuration.

For purchasing teams, retaining both the complete kit reference and individual separator reference improves traceability. It links the separator replacement to the correct major-service event and makes replenishment easier when individual components need to be purchased separately.

Aftermarket equivalents for 23545841 are available, including references such as 39863865 and 42841247 in supplier listings. These numbers should be treated as cross-reference information rather than automatic approval for substitution; filtration efficiency, dimensions, sealing, flow, and vessel fitment must be confirmed.

Exact current package dimensions, package weight, detailed OEM media specifications, and complete application coverage for every 47555208001 revision were not sufficiently verified from authoritative documentation. Those values are therefore intentionally not estimated.

For industrial compressor operators and maintenance professionals, 47555208001 and 23545841 provide a clear reference for separator service within the 8,000-hour air-cooled R90–110 maintenance program. Correct separator identification, proper installation, and inspection of the complete separator system can help control oil carryover and support dependable compressor performance.
