Product Overview
The Ingersoll Rand 47588443001 48958201 Air Filter is an intake air filtration component used in compatible industrial air compressor systems. Its primary function is to remove airborne dust and particulate matter before the incoming air reaches the compressor’s internal components.
In an industrial compressor, intake air quality affects the condition of the air end, lubrication circuit, and downstream separation components. Dust entering the compression system can accumulate on internal surfaces, contaminate circulating oil, and increase wear over time. The air filter helps reduce this contamination by retaining particles in its filtration medium while allowing air to flow toward the compressor inlet.
The 48958201 element is identified in Ingersoll Rand parts listings as an air filter element. It is also cross-referenced with replacement elements such as HIFI-FILTER SA16724 and Baldwin RS5784. The component is associated with multiple industrial compressor applications, so its selection depends on the filter housing and equipment configuration rather than the part number alone.
During normal operation, the compressor draws atmospheric air through the filter. As the filtration medium captures dust, its resistance to airflow gradually increases. If the element becomes excessively loaded, the resulting intake restriction can affect airflow and compressor performance. Regular inspection and replacement help maintain the intended intake conditions.
The filter should be distinguished from coolant filters and air/oil separators. An intake air filter cleans incoming air, a coolant or oil filter removes contaminants from circulating lubricant, and an air/oil separator removes entrained oil from compressed air. Each component serves a separate stage of the compressor system.
For maintenance teams, the 48958201 reference provides a specific identification for intake filtration service. Correct installation, proper sealing, and timely replacement are essential to prevent unfiltered air from bypassing the element and entering the compressor.

Working Principle
The 48958201 Air Filter removes particles from incoming air by passing the airflow through a porous filtration medium. The medium retains contaminants while allowing air to continue through the intake system.
Ambient Air → 48958201 Air Filter → Compressor Intake → Rotary Screw Air End
When the compressor operates, negative pressure at the intake draws air through the filter element. Dust and other suspended particles are captured by the filtration medium, reducing the amount of contamination reaching the compression chamber.
The radial seal helps direct incoming air through the intended filtration path. If the seal is damaged, incorrectly seated, or incompatible with the filter housing, air may bypass the medium. This can allow contaminants to enter the compressor even when the filter material itself remains in reasonable condition.
As particles accumulate, airflow resistance increases. A heavily loaded element can restrict the amount of air supplied to the compressor, potentially affecting capacity and operating efficiency. The actual effect depends on the filter condition, compressor demand, and intake system design.
Filter maintenance should therefore consider both the condition of the filtration medium and the sealing interface. Replacing a clogged element can restore the intended airflow path, while checking the housing and seals helps prevent unfiltered bypass. If airflow problems continue after replacement, the intake valve, ducting, and other possible restrictions should also be examined.
Role in an Ingersoll Rand Compressor System
The 48958201 Air Filter occupies the intake filtration stage, upstream of the compressor air end. It removes airborne contamination before the air enters the compression process, while other filters and separators handle contaminants in the lubricant and compressed-air streams.
Atmospheric Air → Air Filter → Intake Valve → Compressor Air End → Oil Separation System → Compressed Air Outlet

Installation and Maintenance
- Verify the part reference: Confirm that 48958201 is the required air filter element for the installed compressor configuration.
- Prepare the equipment safely: Stop the compressor, isolate the electrical supply, and follow the site’s lockout and tagout procedure.
- Access the intake housing: Open the filter enclosure according to the equipment maintenance procedure.
- Inspect the used element: Look for dust loading, damaged filter material, deformation, or signs of poor sealing.
- Remove the old filter carefully: Avoid releasing accumulated contamination into the clean-air side of the intake housing.
- Clean the filter housing: Remove loose debris from the housing and the filter seating surfaces without pushing contaminants into the intake passage.
- Inspect the radial seal interface: Check the housing contact surface for damage, contamination, or anything that could prevent proper sealing.
- Install the replacement element: Position the filter correctly and ensure that the sealing surface seats evenly.
- Secure the housing: Refit the cover and retaining hardware according to the applicable maintenance procedure.
- Check the intake path: Confirm that the filter and housing are correctly assembled and that no obvious bypass gap remains.
- Inspect operation after restart: Observe available intake restriction indications and check for abnormal airflow behavior.
- Record the service: Document the replacement part number, filter condition, operating hours, and any intake-system issues found during maintenance.

Technical FAQs
What is the purpose of the radial seal on the 48958201 filter?
The radial seal helps prevent incoming air from bypassing the filtration medium. Proper seating is necessary to ensure that intake air passes through the filter rather than entering the compressor through an unfiltered gap.
Which replacement filter references are associated with 48958201?
Cross-reference listings identify HIFI-FILTER SA16724 and Baldwin RS5784 as replacement references. Compatibility depends on the intended application and the filter housing configuration.
Can a clogged intake filter affect compressor output?
Yes. As contamination accumulates, the filter’s resistance to airflow can increase. Excessive restriction may reduce the air available to the compressor and affect operating performance.
What should be inspected if dust is found downstream of the filter?
Inspect the filter medium, radial seal, housing contact surfaces, and installation position. A damaged element or poor seal can allow unfiltered air to bypass the filtration stage. Also examine the intake housing for contamination introduced during maintenance.
