Product Overview
The Ingersoll Rand 47642702001 39911631 Oil Filter is a compressor lubrication-system filter used to remove contaminants from the circulating lubricant. It supports the oil circuit of compatible compressor equipment by helping prevent accumulated particles and debris from continuing through the lubrication path.
In an oil-injected rotary screw compressor, lubricant is circulated through the system to support functions such as lubrication and heat management. The oil filter is installed in the lubrication circuit so that contaminated lubricant is filtered before reaching the components that depend on the oil supply.
Oil cleanliness is particularly relevant to compressors operating for extended periods or under demanding industrial conditions. A restricted filter can increase pressure loss within the lubrication circuit, while a damaged or incorrectly installed filter can reduce the effectiveness of contamination control.
The 39911631 oil filter should be matched to the applicable Ingersoll Rand compressor configuration before replacement. Filter compatibility, sealing condition, installation procedure, and the condition of the surrounding lubrication circuit should be checked during service.

Working Principle
The 39911631 filters circulating compressor lubricant as it passes through the lubrication circuit. Contaminants carried by the oil are retained by the filter medium while filtered lubricant continues toward the components requiring lubrication.
Compressor Oil Circuit → 39911631 Oil Filter → Filtered Lubricant → Lubrication Points / Compressor Components → Oil Return Circuit
As contamination accumulates within the filter, flow resistance can increase. The compressor lubrication system must therefore maintain sufficient oil flow while the filter performs its contamination-removal function.
A restricted, damaged, or incorrectly sealed filter can affect the lubrication circuit. During maintenance, the filter condition should be evaluated together with lubricant condition, filter seals, oil lines, and the associated compressor components.
Role in a Rotary Screw Compressor Lubrication Architecture
The 39911631 occupies the filtration stage of the compressor lubrication circuit. It works with the lubricant reservoir, oil lines, cooling components, and compressor air end to maintain the required oil flow and cleanliness.
Oil Reservoir / Separator → 39911631 Oil Filter → Compressor Lubrication Circuit → Air End / Bearings → Oil Recovery → Oil Circuit
| System Element | Function |
|---|---|
| Separator / Oil Reservoir | Collects and supplies circulating compressor lubricant |
| 39911631 Oil Filter | Removes contaminants from circulating lubricant |
| Oil Lines | Transfer lubricant through the compressor system |
| Compressor Air End | Performs compression and receives lubrication |
| Bearings / Mechanical Parts | Depend on appropriate lubrication where applicable |
| Oil Cooler | Manages lubricant temperature where fitted |
| Oil Recovery Circuit | Returns lubricant within the compressor system |
| Compressor Control | Monitors and manages operating conditions |
The filter supports the lubrication path but does not independently control oil pressure, temperature, or compressor operation.

Installation and Maintenance
- Verify that 47642702001 39911631 matches the intended compressor configuration before installation.
- Shut down and isolate the compressor according to the applicable maintenance procedure.
- Allow the lubrication system and related components to reach a safe servicing condition.
- Relieve applicable system pressure before removing the existing oil filter.
- Inspect the removed filter and lubricant for signs of excessive contamination or abnormal deposits.
- Check the filter mounting area and sealing surface for dirt, damage, or deterioration.
- Inspect the applicable filter seal and replace associated sealing components when required by the maintenance procedure.
- Install the replacement filter correctly without damaging the sealing surface or mounting connection.
- Verify that the filter is securely installed and that no lubricant leakage path is present.
- Check the surrounding oil lines and lubrication connections for signs of leakage or mechanical damage.
- Restart the compressor under controlled conditions and monitor oil-system behavior for abnormal pressure, leakage, or temperature.
- Record the filter replacement and monitor lubricant condition and compressor performance during subsequent operation.

Technical FAQs
What can indicate that the compressor oil filter needs inspection?
Increasing pressure loss, abnormal lubrication-system behavior, contaminated lubricant, or maintenance indicators associated with the compressor can justify inspection. The filter should be evaluated according to the equipment’s maintenance requirements rather than by appearance alone.
Why should the lubricant be inspected when replacing the oil filter?
The condition of the removed filter can reveal accumulated contamination, while the lubricant itself may indicate unusual wear debris or degradation. Reviewing both provides more information about the condition of the lubrication circuit.
What can happen if the replacement filter is not properly sealed?
An incorrectly seated filter or damaged seal can allow lubricant leakage or create a bypass around the intended filtration path. The mounting surface and sealing arrangement should therefore be checked carefully during installation.
Should the oil filter be replaced whenever compressor oil is changed?
The appropriate replacement interval depends on the specific compressor maintenance schedule and operating conditions. The filter should be replaced according to the applicable Ingersoll Rand service requirements rather than assuming every oil change requires an identical procedure.
