Product Overview
The Ingersoll Rand 47555210001 23497001 Pre-Filter is a replacement filtration pad used in compatible Ingersoll Rand rotary screw compressor intake assemblies. Its primary function is to capture airborne dust and coarse particulate matter before the incoming air reaches the protected compressor enclosure and downstream filtration components.
In industrial environments, compressor intake areas are exposed to dust from manufacturing operations, packaging materials, workshop debris, and general airborne contamination. As the compressor draws ambient air into its ventilation and intake arrangement, the pre-filter intercepts a portion of these particles before they accumulate on internal surfaces or reach downstream components.
The 23497001 part number is identified as a pre-filter pad in Ingersoll Rand parts documentation for the standard and outdoor-modification pre-filter assemblies used on selected R90 and R110 compressor configurations. The assembly includes an intake grille, an intake door, retaining hardware, and the filter pad. The exact fitment should be checked against the installed compressor and its intake arrangement before replacement. <Cite refs={[“turn767806search3″,”turn767806search1”]}/>
The pre-filter is distinct from the main compressor air filter. It provides an initial stage of particulate control around the intake assembly, while the main air filter performs the specified filtration of air entering the compression process. Maintaining both components according to their respective service requirements helps preserve the intended airflow path and reduces unnecessary contamination of the compressor interior.

Product Features

- Panel-style filtration: Covers the designated intake opening within the specified assembly.
- Passive operation: Filters air through the media without a separate electrical connection.
- Assembly-level integration: Works with the appropriate intake grille, door, and retaining hardware.
- Routine serviceability: Can be inspected and replaced during scheduled compressor maintenance.
- Separate filtration role: Complements rather than replaces the main compressor air filter.
Working Principle
The 23497001 pre-filter operates through mechanical particle interception. As ambient air passes through the intake assembly, the filter media captures a portion of the airborne dust and coarse contaminants carried by the airflow. The filtered air then continues through the compressor’s designated intake and ventilation paths.
A typical pre-filter arrangement follows this sequence:
Ambient Air → Intake Grille → 23497001 Pre-Filter Pad → Compressor Intake Assembly → Downstream Air Path
The intake grille protects the opening and supports the assembly, while the pad provides the initial filtration surface. The intake door and retaining hardware hold the components in their intended positions. Correct seating is important because gaps around the pad can create bypass paths through which unfiltered air enters the enclosure.
As particles accumulate, the pad may become increasingly loaded with dust. Depending on the operating environment and the filter condition, this can affect airflow through the assembly. A torn, deformed, or poorly seated pad may also reduce filtration effectiveness.
The pre-filter does not replace the main inlet air filter or perform the functions of an oil filter or air/oil separator. These components serve different parts of the compressor system and should be maintained according to their individual requirements.
Role in the Ingersoll Rand Compressor Intake System
The 23497001 occupies the initial filtration position in a compatible compressor intake assembly. It works with the grille and intake door to capture airborne contamination before air moves farther into the equipment.

Installation and Maintenance
- Verify the part number: Confirm 47555210001 and 23497001 against the compressor’s parts list and existing component identification.
- Identify the intake configuration: Check whether the compressor uses the standard or outdoor-modification pre-filter assembly.
- Shut down the compressor: Follow the approved shutdown and isolation procedure before opening the intake assembly.
- Inspect the existing pad: Look for dust loading, tears, deformation, deterioration, or other damage that could affect filtration.
- Check the intake grille: Examine the grille for accumulated contamination, damage, or obstruction.
- Inspect the door and retainers: Verify that the intake door, latches, and retaining hardware can secure the replacement correctly.
- Clean the surrounding area: Remove loose dust and debris without pushing contamination into the downstream intake path.
- Position the replacement: Fit the pad into the designated assembly according to the applicable installation arrangement.
- Check the perimeter: Ensure that the pad is seated correctly and that there are no obvious gaps allowing unfiltered air to bypass the media.
- Inspect the downstream air path: Where accessible, check for contamination or obstruction that could affect airflow.
- Verify reassembly: Secure the grille and intake door, then confirm that all retaining components are correctly fitted.
- Record the maintenance: Document the part number, service date, observed contamination, and any damage found during inspection.

Technical FAQs
Which compressor configurations are associated with the 23497001 pre-filter pad?
The part is listed in pre-filter assembly documentation for selected R90 and R110 configurations. Confirm the compressor model and intake assembly before ordering because other compressor versions may use different pre-filter components.
How does this pre-filter differ from the 23429822 air filter?
The 23497001 is an initial pre-filter pad used in the intake assembly, while the 23429822 is an air filter element for the compressor intake system. Their installation positions and functions differ, so they should not be treated as interchangeable.
What assembly components should be checked when replacing the pad?
Inspect the intake grille, door, latches, retaining hardware, and the seating surfaces. Damage or poor fit can leave gaps around the pad and allow airborne particles to bypass the filtration media.
Can the replacement interval be based on operating hours alone?
Operating hours are useful for planning, but the actual inspection interval should also account for environmental dust levels and the condition of the pad. Follow the applicable maintenance schedule and inspect more frequently where airborne contamination is heavy.
