Product Overview
The Ingersoll Rand 47661941001 39911631 Oil Filter is a replacement filtration component used in the lubrication circuit of compatible Ingersoll Rand compressor systems. It is installed in the oil circulation path to remove suspended contaminants from compressor lubricant before the oil is delivered back to internal operating components.
In rotary screw compressors, lubrication oil performs multiple tasks during operation, including reducing friction between moving parts, assisting heat transfer, and supporting the sealing process inside the compression chamber. As operating hours increase, particles from component wear and oil contamination may accumulate in the lubrication system. The oil filter helps control these impurities and maintain cleaner oil circulation.
This component is different from an air intake filter or oil separator. It does not filter incoming air or separate oil from compressed air output. Its function is focused on protecting the compressor lubrication system and supporting the condition of internal mechanical assemblies.
For maintenance engineers servicing industrial compressed air equipment, the 47661941001 39911631 Oil Filter is normally inspected or replaced during planned compressor maintenance. Correct selection depends on confirming the installed compressor configuration and matching the original filter specification.

Product Features
The Ingersoll Rand 47661941001 39911631 Oil Filter is used in compressor lubrication maintenance where oil quality has a direct influence on internal mechanical conditions.
Key characteristics include:
- Original Ingersoll Rand part number 47661941001 / 39911631
- Designed for compressor oil filtration applications
- Removes particles and contaminants from circulating lubricant
- Helps maintain cleaner oil reaching internal components
- Supports protection of screw rotors, bearings, and lubrication passages
- Suitable for industrial compressor service schedules
- Used in continuous operation compressed air systems
- Works together with oil separators, compressor oil, and other maintenance components
The filter should be selected according to the compressor system requirements rather than only comparing external dimensions, because filtration performance and installation compatibility are also important considerations.
Working Principle
The 39911631 Oil Filter works as a filtration point inside the compressor lubrication circuit.
During compressor operation, lubricant continuously moves through the oil system. Before returning to important mechanical areas, the oil passes through the filter element, where suspended particles and contamination are captured by the filtration media.
The basic process can be described as:
Compressor Oil Circulation → Oil Filter → Clean Lubricant Supply → Internal Mechanical Components
By reducing the amount of contamination circulating with the oil, the filter helps maintain the lubrication condition required by rotating components.
When the filter becomes saturated with collected particles, the oil flow resistance may increase. In practical maintenance work, engineers usually evaluate filter condition together with oil quality, operating hours, temperature conditions, and compressor performance.
Role in a Compressor Lubrication System
The Ingersoll Rand 47661941001 39911631 Oil Filter belongs to the lubrication protection section of a rotary screw compressor.
A typical compressor system includes several connected stages:
Motor Drive → Compression Assembly → Lubrication Circuit → Oil Filter → Oil Separation Section → Compressed Air Output
The oil filter does not control compressor logic or adjust operating parameters. Instead, it supports the mechanical operation of the compressor by helping maintain suitable lubricant conditions.
In industrial environments where compressors run for long periods, maintaining the lubrication path is essential because contamination can gradually affect wear rates, operating temperature, and maintenance requirements.
Industrial Applications
The 47661941001 39911631 Oil Filter is commonly used in industrial compressed air equipment where rotary screw compressors support production operations.
| Application | Typical Use |
|---|---|
| Factory Compressed Air Systems | Maintaining compressor lubrication condition |
| Manufacturing Equipment | Supporting continuous pneumatic supply |
| Automotive Production Lines | Compressor maintenance applications |
| Packaging Machinery | Maintaining air system availability |
| Industrial Processing Facilities | Compressor service replacement |
| Machine Workshops | Routine compressor filtration maintenance |
| Plant Utility Systems | Supporting compressed air infrastructure |
The actual application depends on the compressor model and the installed oil circulation design.
Installation and Maintenance
Before installing a replacement 39911631 Oil Filter, technicians should verify the compressor identification and confirm that the replacement component matches the existing maintenance requirement.
Recommended maintenance practices include:
- Confirm the filter part number before replacement
- Check compressor service history
- Shut down and isolate the compressor system
- Inspect the removed filter condition
- Check the installation area for contamination
- Verify proper sealing during installation
- Confirm no oil leakage after startup
- Monitor compressor operating conditions
- Record maintenance information for future service
During troubleshooting, an oil filter issue should be considered together with other lubrication-related factors, including oil condition, oil separator status, and operating temperature.

Technical FAQs
What is the difference between the 39911631 Oil Filter and a compressor air filter?
The 39911631 Oil Filter works inside the lubrication circuit to clean compressor oil, while an air filter removes contaminants from the incoming air before compression.
Why does compressor oil require filtration during operation?
During continuous operation, lubricant can collect particles from internal wear and external contamination. Filtration helps reduce these particles from circulating through precision mechanical areas.
What should be checked when replacing the 47661941001 filter?
Maintenance personnel should confirm the compressor model, existing filter identification, installation condition, and surrounding lubrication components before replacement.
Can an oil filter condition affect compressor performance?
Yes. A contaminated or restricted oil filter may influence oil circulation conditions. Engineers normally evaluate filter status together with oil quality, operating temperature, and compressor operating data.
