Product Overview
The Ingersoll Rand 47572176001 23523772 Filter Pad is a pre-filter component used in the intake air assembly of compatible Ingersoll Rand rotary screw air compressors. It is identified as a pre-filter pad for the R132 and R160 compressor families, where it is installed as part of the intake enclosure to capture airborne contaminants before they reach the downstream air filtration system.
In industrial compressor installations, the intake system may draw air from rooms containing dust, fibers, packaging debris, or other airborne particles. A pre-filter pad provides an initial filtration stage that helps reduce the amount of contamination entering the main intake filter. This is particularly useful in compressor rooms where the surrounding environment changes with production activity.
The 23523772 pad is used in a pre-filter arrangement associated with the compressor intake door. Unlike a rigid cartridge filter, a pad can cover a broad intake area and intercept particles across the incoming airflow. Its effectiveness depends on the filter medium, the condition of the pad, and the way it is seated within the intake assembly.
A pre-filter and a main air filter serve related but distinct purposes. The pre-filter catches a portion of the incoming particulate load, while the main filter provides the subsequent filtration stage. Keeping the pre-filter in serviceable condition can help limit premature loading of the main filter and reduce the frequency of maintenance caused by excessive environmental contamination.
During routine servicing, technicians should inspect the pad for accumulated dust, tears, deformation, and poor seating around the intake opening. A pad that is heavily loaded can restrict airflow, while a damaged or incorrectly fitted pad may allow contaminants to bypass the intended filtration path.
The 23523772 reference is associated with specified Ingersoll Rand R-Series intake arrangements. It is a pre-filter pad rather than a coolant filter, oil filter, or air/oil separator. Correct identification matters because these components occupy different stages of the compressor system and perform different filtration functions.

Working Principle
The 23523772 Filter Pad operates as the first filtration stage in the applicable compressor intake assembly. Incoming air passes through the porous pad material, which retains a portion of the airborne particles while allowing air to continue toward the main intake filter.
Ambient Air → Pre-Filter Pad → Main Intake Filter → Compressor Intake Valve → Rotary Screw Air End
As air enters the intake enclosure, the pad intercepts particles carried by the airflow. Larger dust particles and other debris are retained within or on the filter medium, reducing the contamination load passed to the next filtration stage.
The pad gradually accumulates contaminants during operation. As the amount of retained material increases, airflow resistance may also rise. In a compressor operating under sustained demand, excessive restriction at the intake can affect the available air supply and should be addressed through inspection and maintenance.
The condition of the pad affects both filtration and airflow. A torn pad may permit contamination to pass around or through the damaged area. Incorrect installation can create gaps between the pad and its supporting frame, allowing air to bypass the intended filtration surface.
Replacing a loaded or damaged pad restores the pre-filter stage when the intake assembly itself remains in good condition. The downstream main air filter must still be maintained according to its own service requirements because the pre-filter does not replace the final intake filtration stage.
Role in an Ingersoll Rand Compressor System
The 23523772 Filter Pad is installed upstream of the main intake filter in the applicable pre-filter assembly. It helps manage the environmental particulate load before air enters the compressor’s primary filtration and compression stages.

Installation and Maintenance
- Verify the part number: Identify the required pre-filter pad as Ingersoll Rand 23523772.
- Prepare the equipment safely: Stop the compressor and follow the site’s electrical isolation and lockout procedures.
- Open the intake assembly: Access the pre-filter arrangement according to the compressor’s maintenance procedure.
- Inspect the existing pad: Look for heavy dust loading, tears, deformation, or other damage that could affect filtration.
- Remove the used pad: Take care not to release accumulated dust into the clean side of the intake enclosure.
- Clean the supporting frame: Remove loose debris from the intake grille, door, and pad seating surfaces.
- Inspect the intake enclosure: Check the supporting components for damage that could prevent the replacement pad from seating correctly.
- Install the replacement pad: Position the new pad within the designated pre-filter arrangement and cover the intended intake area.
- Check the seating: Confirm that the pad lies correctly against its support and that there are no obvious bypass gaps.
- Inspect the main air filter: Assess the downstream filter for contamination or restriction as part of the same maintenance task.

Technical FAQs
What is the difference between the 23523772 Filter Pad and a main air filter?
The 23523772 is a pre-filter pad installed upstream in the applicable intake assembly. It captures part of the incoming particulate load, while the main air filter provides the subsequent filtration stage before air enters the compressor.
Which compressor intake arrangements use the 23523772 pad?
The part is listed for specified Ingersoll Rand R132 and R160 compressor intake assemblies. Its application is associated with the pre-filter arrangement fitted to the intake door.
How can a loaded pre-filter pad affect compressor operation?
As dust accumulates, airflow resistance can increase. Excessive restriction may limit intake airflow, while damaged material or poor seating can allow contaminants to bypass the intended filtration surface.
Should the main air filter also be inspected when replacing the pad?
Yes. The main filter receives the air that has passed through the pre-filter, so its condition should be assessed during the same maintenance task. Replacing the pad does not eliminate the main filter’s separate service requirements.
