Introduction
The Ingersoll Rand 47674732001 23497001 Preventive Maintenance Kit provides a defined reference for scheduled intake-air maintenance on compatible R90–110 compressor equipment. 47674732001 is cataloged as a 4,000-hour preventive maintenance kit, while 23497001 is the associated pre-filter pad used in the compressor intake assembly.
Clean intake air is fundamental to reliable rotary screw compressor operation. Ambient air can contain dust, fibers, and other airborne contaminants, so a properly maintained intake system provides the first line of protection for the compression system.
The 23497001 component has a clearly defined role. In the published R90–160 parts breakdown, it is listed as PAD, PRE-FILTER, with one pad installed in the standard pre-filter assembly. The same assembly includes the intake door, intake grill, hinges, latches, and associated retaining hardware.
The direct maintenance relationship between the two requested references is also well documented. For the R90–110 I configuration, the 47674732001 4,000-hour package lists one 23497001 pre-filter together with the 23429822 air-filter element, 23424922 coolant filter, 23545841 separator element, and 39218193 motor grease.
This arrangement illustrates the role of the pre-filter within a larger maintenance strategy. 23497001 is not intended to replace the primary air filter. Instead, it provides an upstream filtration stage that can intercept larger contamination before it reaches the main element.
Maintaining the pre-filter is particularly useful in environments where airborne dust or other coarse contamination is present. A loaded or deteriorated pad can reduce the effectiveness of the intake system, while a missing or damaged pad may increase the contamination burden placed on the primary filter.
The published intake assembly shows that the pre-filter is integrated into the intake-door arrangement rather than simply suspended inside the compressor cabinet. Correct installation is therefore important: the replacement pad should occupy the intended position and remain properly retained so that incoming air follows the designed filtration path.
During service, technicians should inspect the surrounding intake components at the same time. Dust deposits downstream of the pre-filter can indicate a bypass condition, while damaged grilles, retaining hardware, or sealing surfaces can reduce the effectiveness of the filtration assembly.
The 23497001 reference is also clearly identified by industrial parts suppliers as an Ingersoll Rand pre-filter pad or foam pre-filter. This consistent description makes the part number useful for maintenance records and procurement, especially when several filter components are serviced during the same maintenance event.
The 4,000-hour designation of 47674732001 should be interpreted as part of the compressor's planned maintenance schedule. In the same R90–110 I service data, 47674733001 is listed separately as a 2,000-hour preventive maintenance kit. Selecting the correct package therefore depends on the service interval and the actual compressor configuration.
Pre-filter condition can also affect the service life of the primary air filter. By intercepting larger contaminants upstream, the pre-filter can help reduce the rate at which the main element becomes loaded. However, the actual maintenance interval should still be based on the applicable compressor instructions and operating environment rather than on the pre-filter alone.
A damaged or heavily contaminated pre-filter should not simply be cleaned and returned to service without checking the applicable maintenance procedure. Depending on the assembly design and material condition, replacement may be preferable to continued use.
For procurement teams, retaining both the maintenance-kit number and the individual pre-filter number improves traceability. This is especially useful when different compressor families use different pre-filter references or when the maintenance package is ordered separately from individual replacement components.
The available documentation does not provide sufficiently reliable current engineering specifications for the exact material composition, pad thickness, package dimensions, kit weight, or complete contents of every 47674732001 revision. Those values are therefore intentionally not estimated.
For industrial compressor operators and service professionals, 47674732001 and 23497001 provide a clear reference for scheduled R90–110 intake-system maintenance. Correct pre-filter identification, proper installation, and inspection of the complete intake assembly can help control contamination and support dependable compressor operation.
