The Ingersoll Rand 47555210001 23429822 Air Filter is a replacement intake air filter element used in compatible Ingersoll Rand rotary screw compressors. Its primary function is to remove airborne dust and particulate contamination from incoming air before it reaches the compressor airend. Keeping contaminants out of the compression chamber helps protect internal components from abrasive wear and supports the intended performance of the compressed-air system.
In a compressor operating across multiple production shifts, the intake filter continuously handles air drawn from the surrounding environment. Dust, fibers, and other airborne particles gradually accumulate in the filter media. As the element loads with contamination, airflow resistance can increase, making inspection and timely replacement important parts of routine compressor maintenance.
The 23429822 element is associated with larger Ingersoll Rand compressor configurations, including selected R90 and R110 models. It is also identified in parts listings for the R132 and R160 compressor families. Exact compatibility depends on the compressor model, build configuration, and applicable parts specification, so the full equipment identification should be checked before ordering a replacement.
For maintenance teams, replacing the correct intake filter is more than a routine consumable change. An incorrectly fitted element or one with unsuitable filtration characteristics can compromise the intended intake arrangement. The replacement must match the specified sealing interface, airflow requirements, and installation position.

The 23429822 air filter operates through mechanical filtration. As the compressor draws ambient air into its intake system, the air passes through the filter media, which retains airborne particles while allowing the filtered air to continue toward the compressor airend.
A typical intake arrangement follows this path:
Ambient Air → Intake Filter Element → Compressor Inlet → Airend → Compressed-Air System
During operation, the filter media gradually collects dust and other contaminants. The amount of accumulation depends on the surrounding environment, compressor operating hours, and the condition of the intake area. As contamination increases, the pressure drop across the element may rise, potentially restricting the volume of air available to the compressor.
A filter that is damaged, improperly seated, or incompatible with the housing may also allow unfiltered air to bypass the intended filtration surface. This can expose downstream components to contaminants even when the element appears relatively clean.
The intake air filter performs a different function from the oil filter and air/oil separator. The intake element treats incoming atmospheric air, the oil filter removes contaminants from the circulating lubricant, and the separator removes oil from compressed air in applicable oil-injected compressor designs. Each component must be maintained according to its own service requirements.
The 23429822 is installed in the intake filtration stage of a compatible compressor. It protects the downstream compression process by reducing the amount of airborne contamination entering the airend.

The part is associated with selected Ingersoll Rand R90, R110, R132, and R160 compressor configurations. Compatibility should be confirmed against the complete compressor model and build specification because related models may use different intake arrangements.
As contamination accumulates, airflow resistance may increase and reduce the air available to the compressor. The resulting operating effect depends on the compressor design and operating conditions. Inspect the filter and review relevant operating indications if intake restriction is suspected.
Dust accumulation, damaged retaining components, or defective sealing surfaces can prevent the replacement from seating correctly. These conditions may allow unfiltered air to bypass the element or restrict the intended airflow path.
Interchangeability should not be assumed from the shared product category. Compare the complete part references, compressor application, housing interface, and filtration requirements before selecting an alternative element.
