Product Overview
The Ingersoll Rand 47545145001 39911631 Oil Filter is a replacement filter used in the lubricant circuit of compatible Ingersoll Rand compressor systems. It removes contaminants from circulating compressor oil before the oil returns to components that depend on clean lubrication.
In an oil-injected rotary screw compressor, the lubricant does more than reduce friction. It also participates in cooling and sealing inside the compression system. Dirt and wear particles carried by the oil can affect these functions, making oil filtration a routine part of compressor maintenance.
The 39911631 reference is associated with the oil filter, with 47545145001 shown as the related reference in the product identification. The filter is typically checked or replaced during scheduled service, particularly when the compressor has accumulated significant operating hours or the oil circuit has been exposed to contamination.
For a compressor operating continuously in a factory air system, the oil filter is normally considered together with the compressor oil, air/oil separator, oil cooler, and other lubrication-system components during maintenance.

Working Principle
The oil filter sits in the compressor’s lubricant circulation path.
Oil Reservoir / Separation System → Oil Filter → Compressor Lubrication Circuit → Airend and Other Lubricated Components
As compressor oil passes through the filter, suspended contaminants are retained by the filter media. The filtered oil continues through the lubrication circuit to components requiring lubrication, cooling, and sealing.
Over time, the filter collects particles from normal compressor operation. If contamination builds up or the filter reaches its service limit, oil-flow resistance can increase. This is why the filter condition and replacement interval are checked as part of regular compressor service.
After an oil change, filter replacement is also commonly performed so that the fresh lubricant is not immediately exposed to the contaminants accumulated in the old filter.
Role in an Ingersoll Rand Compressor Lubrication Architecture
The 39911631 Oil Filter belongs to the oil-management side of the compressor rather than the compressed-air discharge path.

Installation and Maintenance
- Confirm the 39911631 part number and related 47545145001 reference before ordering or installing the filter.
- Verify the compressor model and oil-filter configuration.
- Shut down the compressor and isolate the electrical power supply before starting maintenance.
- Release residual pressure from the compressor system according to the applicable service procedure.
- Allow the compressor and lubricant to cool before opening the oil circuit.
- Prepare a suitable collection container if oil is being drained during filter replacement.
- Remove the existing oil filter using the appropriate service procedure and tools.
- Inspect the filter mounting area and sealing surface for contamination or damage.
- Compare the replacement filter with the removed filter before installation.
- Install the new filter and ensure the sealing area is correctly seated.
- Restore the oil level and other service conditions required for compressor operation.
- Start the compressor, check for oil leakage, and monitor operating conditions after replacement.

Technical FAQs
What does the Ingersoll Rand 39911631 Oil Filter remove?
The oil filter captures contaminants and particles carried by the circulating compressor lubricant before the oil continues through the lubrication circuit.
When is the 39911631 normally replaced?
Replacement is generally carried out according to the compressor maintenance schedule or when filter condition, operating conditions, or service requirements indicate that replacement is necessary.
Should the oil filter be replaced when compressor oil is changed?
The applicable compressor maintenance procedure should be followed. Replacing the filter during an oil change is common because the existing filter may contain accumulated contaminants from previous operation.
What should be checked during oil-filter replacement?
The filter part number, mounting area, sealing surface, oil level, and surrounding connections should be checked. After installation, the compressor should be operated and inspected for oil leakage or abnormal conditions.
