The Ingersoll Rand 47545141001 39911631 Oil Filter is an oil filtration component associated with industrial compressed-air equipment. In an oil-lubricated compressor, the oil circuit supports moving components, helps manage friction and heat, and carries contaminants generated during operation. The oil filter helps remove suspended particles from the circulating lubricant before they can continue through the system.
During extended compressor operation, metal wear particles, oxidation residues, and other contaminants can accumulate in the oil. If these materials circulate unchecked, they may contribute to component wear, restricted oil passages, and deterioration of lubrication performance. Maintaining the correct oil filtration arrangement is therefore an important part of compressor servicing.
For maintenance teams managing scheduled overhauls or routine service intervals, identifying the filter by its complete part designation helps distinguish it from other filtration elements used in the same equipment. The 47545141001 and 39911631 identifiers should be retained when documenting replacement parts and planning maintenance inventory.

| Operating Requirements | Must suit the oil circuit and operating conditions of the intended equipment |
As lubricating oil moves through the compressor oil circuit, it passes through the filtration component according to the equipment’s oil-flow arrangement. The filter media retains particles within its effective capture range while allowing oil to continue through the intended flow path.
Contaminants can enter the lubricant through normal component wear, oil degradation, or contamination introduced during servicing. Over time, retained material accumulates in the filter. As the contaminant load increases, the filter may develop greater flow resistance, depending on its construction and operating conditions.
The condition of the oil filter therefore affects more than the cleanliness of the lubricant. Restricted flow can influence the performance of the lubrication system, particularly when the compressor operates for long periods or under demanding loads. A suitable replacement filter restores the intended filtration path when the existing component reaches its service limit.
The exact filtration rating, internal construction, bypass arrangement, and differential-pressure limits for part 47545141001 are not established by the part designation alone. These details should not be assumed when evaluating the filter’s technical performance.
The oil filter operates within the compressor’s lubrication architecture, where oil circulation, filtration, cooling, and delivery work together to support equipment operation.
| System Element | Relationship to the Oil Filter |
|---|---|
| Oil Sump or Reservoir | Stores lubricating oil before it circulates through the system, depending on compressor design |
| Oil Pump or Circulation Mechanism | Moves oil through the lubrication circuit where a separate pumping arrangement is used |
| Oil Filter | Removes suspended contaminants from the oil stream |
| Oil Cooler | Helps control lubricant temperature in systems equipped with an oil-cooling circuit |
| Lubricated Bearings and Moving Components | Receive oil through the system’s designated delivery paths |
| Oil Lines and Internal Passages | Carry lubricant between the filtration component and other parts of the circuit |
| Oil Temperature and Pressure Monitoring | Helps maintenance personnel evaluate operating conditions that may affect filtration and lubrication |
| Service and Replacement Records | Track filter changes, operating hours, and recurring maintenance issues |
The filter’s exact position within this architecture depends on the compressor model. Before installation, the equipment’s parts configuration should be checked to confirm the correct location and flow arrangement.
| Application | Oil Filtration Requirement | Relevance of the Filter |
|---|---|---|
| Industrial Compressed-Air Production | Lubricant must remain suitable for continuous compressor operation | Supports the removal of suspended contaminants from the oil circuit |
| Manufacturing Plant Utilities | Compressor equipment may operate for extended production shifts | Forms part of scheduled lubrication-system maintenance |
| Pneumatic Equipment Supply | Compressor availability affects downstream pneumatic operations | Helps maintain oil cleanliness in the compressor supplying the air system |
| General Industrial Compressor Rooms | Multiple service intervals may need to be coordinated across equipment | Provides an identifiable oil-filter replacement item for maintenance planning |
| Preventive Maintenance Programs | Filters are serviced according to operating conditions and maintenance requirements | Supports documented replacement schedules and spare-parts control |
| Compressor Overhaul Work | Lubrication components are inspected during major service activities | Allows the oil filter to be included in the service checklist where applicable |
| Component | Function | Relationship to the Oil Filter |
|---|---|---|
| Compressor Lubricating Oil | Lubricates applicable internal moving components and carries heat away from contact surfaces | The filter removes suspended contaminants from the circulating oil |
| Oil Cooler | Reduces lubricant temperature in systems using a separate cooling component | Helps maintain suitable oil operating conditions |
| Oil Separator | Separates oil from compressed air in applicable oil-injected compressor designs | Performs a different separation function from the oil filter |

Its stated product category is an oil filter. In an applicable compressor lubrication circuit, an oil filter removes suspended contaminants from circulating lubricant to help limit the recirculation of particulate material.
Interchangeability should not be assumed from the brand or product category alone. The replacement must match the required part identification, installation interface, filtration requirements, and compressor configuration.
Potential warning signs include abnormal oil-pressure indications, evidence of restricted oil flow, oil leakage around the filter connection, or maintenance findings showing excessive contamination. These symptoms can also have other causes and should be evaluated within the complete lubrication system.
The part number alone does not establish the precise micron rating, differential-pressure limit, bypass configuration, or replacement interval. Those values should not be inferred without product-specific technical data and the applicable compressor maintenance requirements.
