Product Overview
The Ingersoll Rand 47627671001 / 24121212 Air/Oil Separator is a compressor service component used to separate entrained oil from compressed air in compatible oil-lubricated compressor systems. It belongs to the air/oil separation stage, where the compressed-air stream is processed before the air continues toward the downstream compressed-air system.
In an oil-lubricated compressor, lubricant is present within the compression process and can become mixed with the compressed air. The separator provides the separation interface needed to remove much of this entrained oil from the air stream and return the separated lubricant to the compressor’s oil circuit.
For maintenance personnel, the separator is particularly relevant during scheduled compressor servicing, oil-circuit maintenance, or troubleshooting involving changes in oil carryover and separator performance. The 47627671001 and 24121212 references should be checked against the installed compressor configuration before replacement.

Working Principle
The 47627671001 / 24121212 operates in the air/oil separation stage of an oil-lubricated compressor. During compression, oil becomes entrained in the compressed-air stream. The separator provides a medium through which the air and oil can be separated, allowing the compressed air to continue downstream while separated oil is directed back toward the lubrication circuit where the compressor design provides for oil recovery.
A simplified process path is:
Compression Process → Oil-Laden Compressed Air → Air/Oil Separator → Separated Compressed Air → Downstream Air System
The separation element gradually accumulates material and can change in operating condition as the compressor runs. For that reason, separator condition is considered during scheduled service as well as when the compressor shows changes in oil carryover or other operating indications.
The separator is a passive component. It does not independently control pressure, measure oil concentration, or regulate compressor output. Its function is to support physical separation within the compressor’s air/oil management system.
Role in a Compressor Air/Oil Separation Architecture
The air/oil separator forms part of the transition between the compression process and the downstream compressed-air path. It helps reduce the amount of lubricant carried forward with the compressed air while supporting the compressor’s internal oil-management cycle.
| System Layer | Typical Component | Function |
|---|---|---|
| Compression Stage | Oil-Lubricated Compressor | Produces compressed air while using circulating lubricant |
| Air/Oil Mixture | Oil-Laden Compressed Air | Carries entrained lubricant from the compression process |
| Separation Stage | 47627671001 / 24121212 | Separates oil from the compressed-air stream |
| Oil Recovery | Oil Return Circuit | Directs separated oil back into the lubrication system where applicable |
| Compressed-Air Path | Downstream Air Passage | Carries separated compressed air toward the outlet system |
| Additional Filtration | Downstream Air Treatment | Provides further air treatment where installed |
| Plant Air System | Compressed-Air Network | Receives and distributes compressed air |

Installation and Maintenance
- Confirm the part identification — Verify that 47627671001 / 24121212 matches the compressor model and installed air/oil separation arrangement.
- Shut down the compressor — Stop the equipment and follow the applicable lockout and isolation procedure before accessing the separator.
- Depressurize the system — Ensure the relevant compressor vessels, passages, and connected components are at a safe pressure before opening the air/oil system.
- Allow the equipment to cool — Compressor oil and surrounding components may remain hot after operation, so allow sufficient cooling before maintenance.
- Inspect the separator area — Check for oil leakage, contamination, damaged connections, or other abnormal conditions around the existing separator.
- Remove the existing component carefully — Follow the applicable service procedure and control oil residue or contamination during removal.
- Inspect the mounting and sealing surfaces — Check the separator connection, sealing areas, and associated hardware for damage or contamination.
- Prepare the replacement separator — Verify the part references and inspect the replacement component for visible damage before installation.
- Install the separator correctly — Fit the replacement according to the compressor service procedure and ensure all applicable connections and seals are correctly positioned.
- Check the air and oil paths — Confirm that the separator installation does not obstruct the intended compressed-air or oil-return path.
- Restart and monitor the compressor — Return the equipment to service using the normal startup procedure and observe oil and compressed-air system indications.
- Record the maintenance activity — Document the separator replacement, part references, compressor identification, and any relevant observations for future service.

Technical FAQs
What does the 47627671001 / 24121212 air/oil separator do?
It separates entrained lubricant from the compressed-air stream in compatible oil-lubricated compressor systems. The separated oil can be directed back into the lubrication circuit where the compressor design provides an oil-return path.
What can indicate a problem with the air/oil separation system?
Changes in oil carryover, abnormal oil consumption, or other compressor operating indications can lead to inspection of the separator and related components. These symptoms can also have other causes, so the complete air/oil system should be checked during troubleshooting.
Why must the compressor be depressurized before separator replacement?
The separator is connected to the compressor’s air and oil system, which can contain stored pressure and hot lubricant after operation. The equipment must be isolated and brought to a safe condition before the separation system is opened.
What should be verified before installing this separator?
The compressor model, existing separator identification, mounting arrangement, sealing interfaces, and the 47627671001 / 24121212 part references should be checked against the applicable equipment documentation. Compatibility should be confirmed before installation.
