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.

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:
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.
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:
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.
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.
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.
Correct installation of the 47661942001 39911631 Oil Filter requires confirmation of the compressor configuration and existing filter specification.
Recommended maintenance procedures include:
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.
The oil filter operates together with other compressor system components.
| Component | Function |
|---|---|
| Compressor Oil | Provides lubrication and heat transfer |
| Oil Separator | Separates oil from compressed air stream |
| Air Filter | Removes contaminants from intake air |
| Compression Element | Performs air compression |
| Oil Cooler | Controls lubricant temperature |
| Compressor Motor | Provides driving force |
| Temperature Sensors | Monitor operating conditions |
| Pressure Monitoring Devices | Detect system pressure changes |
A complete compressor maintenance inspection normally includes filtration, lubrication, and cooling components together.
| Model / Part Number | Product Type | Typical Application |
|---|---|---|
| Ingersoll Rand 47661942001 / 39911631 | Oil Filter | Compressor lubrication filtration |
| Ingersoll Rand 47661941001 / 39911631 | Oil Filter | Alternative compressor oil filtration application |
| Ingersoll Rand 47661941001 / 47638842001 | Air Filter | Compressor intake filtration |
| Ingersoll Rand 47661941001 / 47638843001 | Safety Filter Element | Secondary intake protection |
| Ingersoll Rand 47661941001 / 80060239 | Compressor Coolant | Cooling and lubrication maintenance |
Selection should be based on compressor model compatibility and system requirements rather than appearance or size comparison alone.
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.
High operating hours, contaminated working environments, extended compressor loading, and changes in oil condition may increase the need for inspection or replacement.
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.
After replacement, technicians should confirm correct installation, check for leakage, monitor oil-related operating conditions, and verify that the compressor returns to normal operation.
