Introduction
The Ingersoll Rand 47555208001 23497001 Air-Cooled Preventive Maintenance Kit combination covers the intake pre-filtration portion of the major maintenance program for compatible R90–110 compressors. 47555208001 identifies the 8,000-hour air-cooled service event, while 23497001 identifies the dedicated pre-filter pad.
Pre-filtration provides an additional layer of protection ahead of the primary air filter. Ambient compressor-room or outdoor air can contain dust, fibers, and other airborne particles. Removing larger contamination before it reaches the main filter can help maintain cleaner intake conditions.
The 23497001 part has a particularly clear documented application. Ingersoll Rand's published parts drawing lists 23497001, quantity 1, PAD, PRE-FILTER in the standard/ODM pre-filter assembly. The same drawing shows the intake door, intake grill, hinges, latches, and retaining hardware required to support the pad.
This means 23497001 is not simply an unspecified sheet of filter media. It is a designated component of the intake assembly, so correct fit, retention, and airflow characteristics matter.
Pre-filter condition is especially important in dusty environments. A heavily loaded pad can restrict intake airflow, while a missing or damaged pad can allow more coarse contamination to reach the primary air filter. Routine inspection therefore provides a useful early indication of intake-system condition.
The standard pre-filter assembly is distinct from the high-dust version. The published high-dust assembly uses separate panel filters and foam components rather than the standard 23497001 pad. This distinction is important when determining the correct replacement for a particular compressor configuration.
During maintenance, technicians should inspect the complete intake assembly rather than replacing the pad alone. Dust accumulation downstream of the pad can indicate bypass, while damaged hinges, latches, grills, retainers, or door surfaces can affect how effectively the pre-filter performs.
The pre-filter also works together with the primary air filter. It should not be treated as a substitute for the main filter element. The primary air filter should be serviced according to its own maintenance requirements and the actual operating environment.
The relationship between 47555208001 and 23497001 should be recorded carefully in maintenance documentation. The kit number identifies the broader 8,000-hour service event, while 23497001 identifies an individual intake component. This distinction improves traceability when complete kits and individual spares are purchased separately.
OEM-oriented suppliers consistently describe 23497001 as an Ingersoll Rand pre-filter pad, while equivalent aftermarket products are also available. Aftermarket equivalents should be evaluated against the original assembly requirements rather than selected solely from appearance.
The operating environment should also be considered. A compressor installed in a dusty manufacturing area, outdoor location, or other contaminated environment may load the pre-filter more rapidly than a clean indoor installation. Inspection frequency should therefore reflect actual conditions as well as the formal maintenance schedule.
When replacing the pad, the intake assembly should be cleaned and checked for proper retention. The pad must remain positioned so that incoming air passes through the intended filter media rather than around it.
For purchasing teams, recording the compressor model, serial number, intake configuration, 47555208001 maintenance reference, and 23497001 part number together provides a robust procurement trail.
Exact package contents for every 47555208001 revision, current pad dimensions, thickness, material formulation, package dimensions, and kit weight were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.
For industrial compressor operators and maintenance professionals, 47555208001 and 23497001 provide a useful reference for intake pre-filtration service within the 8,000-hour air-cooled maintenance program. Correct part identification, proper installation, and complete intake-assembly inspection can help maintain clean intake conditions and support reliable compressor operation.
