Introduction
The Ingersoll Rand 47555212001 23497001 Air-Cooled Preventive Maintenance Kit with Modification combination covers the intake pre-filtration portion of the modified 8,000-hour major-service program for R90–110 I compressors. The published service table identifies 47555212001 as the 8,000-hour air-cooled package with MOD and lists one 23497001 pre-filter.
Clean intake air is fundamental to reliable rotary screw compressor operation. Ambient air contains dust and other airborne contamination, and the intake system uses multiple filtration stages to limit particulate entry into the compressor.
The 23497001 component is specifically identified as a pre-filter pad, distinguishing it from the primary cylindrical air-filter element. Its function is to provide an upstream filtration stage that helps reduce the amount of coarse contamination reaching the main filter.
The direct relationship between the requested references is clear: the published R90–110 I service configuration specifies one 23497001 within 47555212001. The same package lists 23429822 as the main air filter, 23424922 as the coolant filter, 23545841 as the separator, and 23531577 as the minimum-pressure-valve kit.
The important procurement distinction is the MOD status of 47555212001. The modification does not change the pre-filter reference. Instead, the published package changes other configuration-specific service components, including the inlet-valve service reference to 47553881001.
This means maintenance teams should not assume that every component changes between standard and modified packages. Recurring filtration components can remain the same while modified assemblies elsewhere in the machine require different parts.
Pre-filtration is especially valuable in dusty or contaminated environments. A properly maintained pad can reduce the coarse-particle burden on the primary filter, while a missing, damaged, or poorly fitted pad may increase contamination reaching the main element.
During maintenance, the pre-filter should be inspected together with the complete intake assembly. The pad, retaining arrangement, intake surfaces, and surrounding areas should be checked for contamination, damage, deformation, or conditions that could allow air to bypass the intended filtration path.
The primary filter should not be considered interchangeable with the pre-filter. The R90–110 I package separately identifies 23429822 as the air filter and 23497001 as the pre-filter.
The 23497001 reference is also used in other R90–110 I maintenance packages. The published service table lists it in both standard and modified 8,000-hour air-cooled packages as well as the water-cooled R90–110 I packages. Therefore, the individual part number does not by itself identify the complete maintenance configuration.
For purchasing teams, the preferred record should include the compressor model, serial number, cooling arrangement, modification status, complete kit number, and individual component number. Ingersoll Rand's current parts-finder guidance likewise emphasizes selecting parts based on the exact compressor model and equipment configuration.
Aftermarket versions of 23497001 are available, but a generic filter pad should not be selected solely on visual similarity. The replacement must match the intended intake assembly and provide suitable airflow and filtration characteristics.
Before installation, the intake assembly should be cleaned and the pad positioned and retained correctly so that incoming air passes through the filter media rather than around it.
Exact current pad dimensions, thickness, media formulation, package dimensions, kit weight, and complete revision-specific contents were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.
For industrial compressor operators and maintenance professionals, 47555212001 and 23497001 provide a clear reference for intake pre-filtration within the modified 8,000-hour air-cooled R90–110 I maintenance program. Correct configuration matching and proper pre-filter installation can help control intake contamination and support dependable compressor operation.
