Introduction
The Ingersoll Rand 47555465001 23497001 combination covers the intake pre-filtration portion of a major water-cooled compressor maintenance program. 47555465001 is the 8,000-hour water-cooled maintenance-kit reference, while 23497001 identifies the pre-filter pad used in the compressor's intake assembly.
The intake system is the first protection stage for the compressor air path. Atmospheric air can contain dust, fibers, and other airborne contamination, so a properly maintained pre-filter can intercept larger particles before they reach the primary air-filter element.
The 23497001 reference is particularly well defined in the available parts documentation. The published Ingersoll Rand assembly drawing lists 23497001, quantity 1, PAD, PRE-FILTER in the standard/ODM pre-filter assembly. The same drawing identifies the associated intake door, grill, hinges, latch, wing nuts, and washers.
This means 23497001 is not simply a generic filter sheet. It is a designated component of a specific intake assembly, so its physical fit and airflow characteristics matter.
Pre-filtration is especially useful where compressors operate in dusty or contaminated environments. A properly maintained pad can reduce the particulate load reaching the main filter, while a missing, damaged, or poorly fitted pad can increase the potential for contamination to move farther into the intake system.
During planned maintenance, the pre-filter should be inspected together with the complete intake assembly. Dust deposits downstream of the pad can indicate bypass, while damaged retaining hardware, deformed intake panels, or deteriorated sealing surfaces may also compromise filtration performance.
The 47555465001 kit represents a major maintenance interval rather than a simple pre-filter replacement. An 8,000-hour service program can include recurring filtration components as well as additional service work on valves, separation, cooling, pressure control, and lubrication systems. The exact package contents should therefore be verified by compressor configuration.
The 23497001 part is independently identified by several parts suppliers as an Ingersoll Rand pre-filter pad, including OEM-oriented listings. This supports using the exact part number in maintenance records rather than purchasing unspecified filter media.
A replacement should be installed according to the equipment's service procedure. The pad should be correctly positioned and retained so that incoming air passes through the intended filtration material rather than around it.
The pre-filter should also not be confused with higher-dust or panel-filter configurations. The available parts breakdown distinguishes the standard/ODM pre-filter assembly from the separate high-dust pre-filter assembly, which uses different panel components. This is another reason to confirm the intake configuration before substituting parts.
The 23497001 reference is also offered by aftermarket suppliers as an equivalent or replacement filter mat. Such products can be useful for sourcing, but they should be evaluated against the OEM assembly requirements rather than assumed interchangeable merely because they have the same part number description.
For maintenance teams, a useful inspection routine includes checking the pre-filter condition, intake grill, door, retainers, hinges, and surrounding cabinet surfaces. This can identify developing airflow restrictions or contamination paths before they become larger problems.
For purchasing departments, retaining 47555465001 as the service-kit reference and 23497001 as the individual pre-filter reference provides clear traceability. This is particularly valuable where multiple R-Series models use different pre-filter arrangements.
Exact package contents for every 47555465001 revision, pre-filter material specification, pad dimensions, thickness, package dimensions, and weight were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.
For industrial compressor operators and service professionals, 47555465001 and 23497001 provide a clear reference for scheduled intake pre-filtration maintenance. Correct part identification, proper installation, and inspection of the complete intake assembly can help maintain clean intake conditions and support reliable compressor operation.
