Product Overview
The Ingersoll Rand 47667846001 39911631 Oil Filter is a replacement oil filter used in compatible Ingersoll Rand compressor systems. It is part of the compressor lubrication circuit, where filtration is required to keep circulating lubricant free from contaminants that could affect internal mechanical components.
During compressor operation, lubricant moves through the lubrication system and can carry fine particles generated by normal mechanical wear, contamination introduced during servicing, or other debris. The oil filter captures these contaminants before the oil continues through the relevant lubrication path.
The 39911631 oil filter is suited to scheduled compressor maintenance and filter replacement work. Replacing the filter at the appropriate service interval helps maintain the condition of the lubrication circuit and reduces the possibility of accumulated contaminants circulating through the compressor.
For maintenance technicians, the oil filter should be treated as part of the complete lubrication system rather than as an isolated consumable. Correct filter selection, installation, sealing, and post-service inspection are important when returning the compressor to operation.

Working Principle
The 39911631 oil filter operates as a filtration barrier within the compressor lubrication circuit. Lubricant entering the filter passes through the filter media, while particles and contaminants are retained by the filtration element.
Compressor Oil Circuit → 39911631 Oil Filter → Filtered Lubricant → Lubricated Compressor Components
As the compressor operates, the filter continuously handles lubricant flowing through the designated oil circuit. The filtration process helps prevent accumulated contaminants from continuing downstream toward components that depend on clean lubricant.
Filter condition can change over the service interval as contaminants accumulate in the filter media. A filter that is heavily contaminated can affect oil flow through the lubrication circuit, which is why filter replacement forms part of routine compressor maintenance.
The oil filter does not regulate compressor pressure or control compressor operation. Its function is specifically related to maintaining the cleanliness of the circulating lubricant.
Role in an Ingersoll Rand Compressor Lubrication System
The 39911631 occupies the filtration layer of the compressor lubrication system. It works together with the oil circuit and mechanical components that depend on properly filtered lubricant.
Compressor Oil Circuit → 39911631 Oil Filter → Lubrication Circuit → Compressor Mechanical Components
| System Element | Function |
|---|---|
| Compressor Oil Circuit | Circulates lubricant through the compressor |
| 39911631 Oil Filter | Removes contaminants from the circulating lubricant |
| Oil Lines and Connections | Transfer lubricant between system components |
| Compressor Bearings | Receive lubrication to support rotating components |
| Compressor Mechanical Assembly | Performs compression and mechanical power transmission |
| Oil Cooler | Helps manage lubricant temperature where fitted |
| Compressor Controller | Monitors and controls compressor operating functions |
A clean filter supports the overall lubrication circuit, but filter condition should be evaluated together with oil condition, operating temperature, pressure behavior, and the condition of other compressor components.
Industrial Applications
| Application | Typical Use |
|---|---|
| Screw Compressor Maintenance | Scheduled replacement of compressor oil filters |
| Industrial Air Compression | Lubricant filtration during compressor operation |
| Preventive Maintenance | Routine replacement of used filter elements |
| Compressor Overhaul | Installation of new filtration components during servicing |
| Manufacturing Plants | Maintenance of compressed-air equipment |
| Process Industries | Lubrication-system filtration for compatible compressors |
| Plant Utility Systems | Maintaining compressor lubrication-system cleanliness |
Installation and Maintenance
- Confirm that 39911631 is the correct oil filter for the compressor being serviced.
- Shut down and isolate the compressor before beginning filter replacement.
- Allow the equipment to reach a safe maintenance condition before opening the oil circuit.
- Release or control residual pressure according to the approved compressor service procedure.
- Clean the area around the existing filter before removal to prevent contaminants from entering the oil circuit.
- Inspect the removed filter and surrounding components for unusual contamination or signs of abnormal wear.
- Check the replacement filter and sealing surfaces before installation.
- Install the filter correctly and ensure the connection is properly seated.
- Restore the oil circuit and inspect the filter area for leakage.
- Start the compressor under controlled conditions and observe the lubrication system for abnormal indications.
- Check operating conditions after replacement and investigate unusual oil pressure, temperature, or flow behavior.
- Record the filter replacement and related observations in the compressor maintenance history.

Technical FAQs
What contaminants does the 39911631 oil filter help remove?
The oil filter is intended to retain particulate contamination and debris present in the circulating compressor lubricant. The type and quantity of contamination can depend on equipment condition, operating environment, lubricant condition, and maintenance practices.
What symptoms can indicate that an oil filter requires attention?
Abnormal oil pressure or flow behavior, increased operating temperature, or unusual lubrication-system indications can justify inspection of the filter and surrounding oil circuit. These symptoms can also originate from other lubrication-system components and should not automatically be attributed to the filter.
Why should the oil filter be replaced during scheduled compressor maintenance?
The filter gradually accumulates retained contaminants during operation. Replacing it at the appropriate service interval helps maintain the intended filtration function and reduces the risk of excessive restriction caused by a heavily loaded filter.
What should be checked after installing a new 39911631 oil filter?
Check that the filter is correctly installed and sealed, then inspect for leakage after restoring the compressor to service. Operating oil pressure, temperature, and other relevant lubrication indications should also be monitored for abnormal behavior.
