Product Overview
The Ingersoll Rand 47642702001 47701891001 Air Filter is a compressor intake filtration component used to remove airborne dust and particulate contamination before air enters the compressor air-end. It forms the first filtration stage of the compressor air path and helps protect internal components from contaminants carried in the incoming air.
In a rotary screw compressor installation, the intake filter is positioned upstream of the compression stage. Ambient air passes through the filter media before reaching the compressor inlet, allowing particulate matter to be retained while filtered air continues into the compression system.
Intake air quality can affect compressor maintenance requirements, particularly in plants exposed to dust, process particles, or other airborne contaminants. A loaded or damaged filter can also restrict the inlet air path and affect compressor operating conditions, making filter inspection part of routine compressor service.
The 47701891001 filter should be matched to the applicable compressor configuration before installation. Correct fitment, sealing, filter condition, and the cleanliness of the intake housing should be verified during replacement.

Product Features
- Air Filter for compatible Ingersoll Rand compressor systems
- Removes airborne particulate contamination from intake air
- Protects the compressor air-end from contaminants entering through the inlet
- Forms part of the compressor intake air path
- Suitable for scheduled compressor filter replacement
- Supports cleaner air delivery to the compression stage
- Useful in industrial environments where airborne contamination is present
- Requires correct filter and compressor compatibility verification
Working Principle
The 47701891001 operates by passing incoming ambient air through a filter medium that retains particulate matter. Cleaned air then continues toward the compressor’s intake and compression stage.
Ambient Air → 47701891001 Air Filter → Filtered Intake Air → Compressor Air End → Compressed Air System
As the filter accumulates dust and other particles, airflow resistance can increase. The compressor intake system must therefore maintain an appropriate balance between filtration and unrestricted airflow.
A damaged, poorly sealed, or heavily loaded filter can allow contaminants to enter the compressor or create excessive restriction at the inlet. Inspection of the filter should therefore include both the filter element and the surrounding intake housing and sealing surfaces.
Role in a Rotary Screw Compressor Air Intake Architecture
The 47701891001 occupies the air-filtration stage immediately upstream of the compressor intake. It protects the downstream air-end while maintaining the required airflow path for compression.
Ambient Air → Intake Housing → 47701891001 Air Filter → Compressor Inlet → Air End → Air/Oil Separation → Compressed Air Outlet
| System Element | Function |
|---|---|
| Ambient Air | Provides the incoming air supply |
| Intake Housing | Directs incoming air toward the filter |
| 47701891001 | Removes airborne particulate contamination |
| Compressor Inlet | Transfers filtered air into the compression stage |
| Air End | Compresses the filtered intake air |
| Air/Oil Separator | Separates lubricant from compressed air |
| Aftercooler | Reduces compressed-air temperature where applicable |
| Compressed Air System | Delivers processed air to downstream equipment |
The intake filter protects the compression stage without participating in compressor control or air/oil separation.

Installation and Maintenance
- Verify that 47642702001 47701891001 matches the intended compressor before installation.
- Shut down and isolate the compressor according to the applicable maintenance procedure.
- Ensure the intake system is in a safe condition before opening the filter housing.
- Remove the existing filter carefully to avoid releasing accumulated contaminants into the intake path.
- Inspect the filter housing for dust buildup, foreign material, damage, or corrosion.
- Check the filter sealing surfaces and associated seals for deterioration.
- Clean the intake housing as required without allowing contamination to enter the compressor inlet.
- Install the replacement filter in the correct orientation and seating position.
- Verify that the filter seals correctly against the designated housing surfaces.
- Secure the intake housing and confirm that no unfiltered air path remains around the filter.
- Start the compressor under controlled conditions and check for abnormal intake restriction or operating behavior.
- Record the filter replacement and establish the next inspection or replacement interval according to operating conditions and the applicable maintenance procedure.

Technical FAQs
How does a loaded intake filter affect compressor operation?
As particulate matter accumulates, airflow resistance can increase. Excessive restriction may affect compressor intake conditions, so a loaded filter should be inspected and serviced according to the applicable maintenance procedure.
What should be inspected besides the filter element during replacement?
The intake housing, sealing surfaces, associated seals, ducting, and inlet path should also be inspected. A new filter cannot prevent contamination effectively if unfiltered air can bypass it through a damaged or poorly sealed connection.
Can an air filter be cleaned and reused instead of replaced?
The appropriate service method depends on the specific filter and compressor maintenance procedure. A filter should not be cleaned or reused unless the applicable equipment documentation permits that practice.
What should be checked after installing the 47701891001?
Confirm that the filter is correctly seated and sealed, the intake housing is properly secured, and the compressor operates without abnormal intake restriction. The intake path should also be checked for evidence of unfiltered-air entry.
