Product Overview
The Ingersoll Rand 47661942001 39911631 Oil Filter is a compressor maintenance filter component used in the lubrication circuit of compatible rotary screw compressor systems. It is installed within the oil circulation path, where it removes solid contaminants from the compressor lubricant before the oil returns to internal operating assemblies.
In a rotary screw compressor, lubricant is continuously circulated to support several mechanical functions, including reducing friction, assisting heat transfer, and maintaining proper sealing conditions inside the compression unit. During long-term operation, particles generated from component wear or oil contamination may accumulate within the lubrication system. The oil filter helps control these contaminants and maintain cleaner oil flow.
This component has a different function from compressor air filters and oil separators. The air filter protects the compressor intake side, while the oil separator manages oil separation from compressed air. The 39911631 Oil Filter focuses specifically on maintaining lubricant cleanliness inside the compressor system.
For maintenance engineers, this type of filter is commonly checked during scheduled compressor servicing or when lubrication-related operating conditions require inspection. Proper identification of the compressor model and installed filtration configuration is important before replacement.

Product Features
The Ingersoll Rand 47661942001 39911631 Oil Filter is used in compressor lubrication systems where maintaining oil cleanliness is necessary for mechanical protection.
Key features include:
- Ingersoll Rand compressor oil filtration component
- Model 47661942001 / 39911631
- Filters contamination from circulating compressor lubricant
- Supports cleaner oil supply to internal mechanical parts
- Helps reduce particle-related wear in lubrication areas
- Suitable for rotary screw compressor maintenance programs
- Used in industrial compressed air applications
- Works together with compressor oil, oil separators, and cooling components
During compressor maintenance, filter replacement should be evaluated together with oil condition, operating hours, and system performance rather than only the external condition of the filter element.
Working Principle
The 39911631 Oil Filter operates by directing compressor lubricant through a filtration medium before the oil reaches critical internal components.
A simplified lubrication flow can be described as:
Oil Reservoir → Oil Circulation Path → Oil Filter → Compression Components → Return Circuit
As the compressor operates, oil carries suspended particles through the lubrication system. The filter element captures these contaminants, allowing cleaner lubricant to continue through the circuit.
The filtration process helps:
- Reduce solid particles circulating with compressor oil
- Protect internal mechanical clearance areas
- Maintain cleaner lubrication conditions
- Support normal operation of rotating assemblies
When contamination accumulates inside the filter element, flow resistance may increase. Maintenance personnel normally review operating conditions, oil quality, and service records when determining replacement requirements.
Role in a Rotary Screw Compressor System
The Ingersoll Rand 47661942001 39911631 Oil Filter is positioned within the compressor lubrication management section.
A typical compressor maintenance structure can be viewed as:
Motor System → Compression Element → Lubrication Circuit → Oil Filter → Oil Separation System → Air Output
The oil filter does not control compressor operation or process compressed air. Its function is associated with maintaining the condition of the lubricant circulating through the machine.
For compressors operating continuously in industrial environments, lubrication cleanliness is an important factor affecting internal component wear, maintenance intervals, and equipment condition.
Industrial Applications
The Ingersoll Rand 47661942001 39911631 Oil Filter is used in industrial compressed air systems that rely on rotary screw compressors.
| Application | Typical Use |
|---|---|
| Manufacturing Facilities | Compressor lubrication maintenance |
| Automotive Production | Supporting continuous compressed air operation |
| Packaging Systems | Maintaining compressor service condition |
| Process Industries | Compressor preventive maintenance |
| Industrial Equipment Plants | Replacement filtration component |
| Factory Utility Systems | Supporting compressed air infrastructure |
| Mechanical Workshops | Compressor repair and servicing |
The actual application depends on the compressor model and installed lubrication system design.
Installation and Maintenance
Correct installation of the 47661942001 39911631 Oil Filter requires confirmation of the compressor configuration and existing filter specification.
Recommended maintenance procedures include:
- Verify the filter model before installation
- Confirm compressor service requirements
- Shut down and isolate the compressor system
- Inspect the removed filter condition
- Check the filter mounting area
- Verify sealing surfaces before installation
- Install the replacement element correctly
- Check for oil leakage after startup
- Monitor operating conditions after replacement
- Record maintenance information
If abnormal oil pressure or temperature conditions appear after filter replacement, technicians should inspect the complete lubrication circuit rather than focusing only on the filter.
Related Components
The oil filter operates together with other compressor system components.

Technical FAQs
How does the 47661942001 39911631 Oil Filter differ from an intake air filter?
The oil filter works inside the lubrication circuit to remove contaminants from compressor oil, while the intake air filter protects the compressor from particles entering through the suction side.
What operating conditions may increase oil filter replacement requirements?
High operating hours, contaminated working environments, extended compressor loading, and changes in oil condition may increase the need for inspection or replacement.
Why should the oil filter be checked together with compressor oil condition?
The filter and lubricant work as part of the same circulation system. Oil contamination levels can influence filter loading, while filter condition can affect the cleanliness of oil reaching internal components.
What should maintenance personnel verify after replacing the 39911631 Oil Filter?
After replacement, technicians should confirm correct installation, check for leakage, monitor oil-related operating conditions, and verify that the compressor returns to normal operation.
