Product Overview
The Ingersoll Rand 47627050001 54749247 Air/Oil Separator is a separation component used in compatible rotary screw air compressors. Its purpose is to separate lubricant mist from compressed air before the air leaves the compressor. This process helps limit oil carryover into downstream piping, air treatment equipment and pneumatic machinery.
In oil-flooded rotary screw compressors, lubricant enters the compression process to support sealing, lubrication and heat removal. After compression, the air and oil must be separated so that the recovered lubricant can return to the compressor’s oil circuit while the compressed air continues toward the discharge system.
Part number 54749247 is associated with Ingersoll Rand SSR UP5, UP6 and EW5 compressor applications. The supplied reference 47627050001 is retained as provided for this product listing. Compatibility should be checked against the installed compressor model and separator arrangement, since the correct element depends on the equipment configuration.
Separator condition affects both oil carryover and airflow resistance. An element that becomes restricted or loses separation performance may contribute to increased pressure drop or elevated oil content in the discharge air. Correct replacement and installation are therefore important parts of routine compressor maintenance.

Product Features
- Oil mist separation: Helps remove suspended oil droplets from compressed air leaving the compression stage.
- Lubricant recovery: Supports the return of separated oil to the compressor lubrication circuit where the system provides for recovery.
- Downstream protection: Helps limit oil carryover into air treatment equipment and connected pneumatic machinery.
- Defined part reference: Supports spare-parts identification and maintenance records.
- Compressor-specific compatibility: Must match the installed separator housing and compressor configuration.
- Maintenance replacement: Allows the separation element to be renewed when required by the service schedule or its operating condition.
- Sealing interface: Correct installation helps prevent compressed air and oil from bypassing the intended separation path.
Working Principle
The separator receives the air-and-oil mixture produced during compression. As the mixture passes through the coalescing media, fine oil droplets collect on the fibres and combine into larger droplets. The separated oil can then drain toward the designated oil-return path, while the compressed air continues through the separator outlet.
During normal operation, the separator must balance oil removal with acceptable airflow resistance. As the media accumulates contamination or deteriorates, the pressure drop across the element may rise. Separation performance can also decline if the element is damaged, incorrectly installed or fitted with an unsuitable sealing arrangement.
For maintenance personnel, oil carryover and abnormal differential pressure are useful indicators to investigate, but neither symptom automatically proves that the separator is the only cause. Oil level, operating conditions, the oil-return arrangement and other parts of the compressor system may also need inspection.
The separator is part of the compressed-air and lubricant separation process. It does not replace the compressor oil filter, which removes particulate contaminants from circulating lubricant, or the intake air filter, which treats atmospheric air before compression.
Role in an Industrial Air Compressor System
The air/oil separator sits downstream of the compression stage in an oil-flooded compressor. It separates lubricant from the compressed-air stream and supports the return of recovered oil to the lubrication system.

Installation and Maintenance
- Verify the part references: Confirm that 47627050001 and 54749247 match the required separator identification.
- Identify the compressor model: Check the equipment nameplate and parts configuration before removing the existing element.
- Shut down and isolate the compressor: Follow the prescribed shutdown procedure and prevent unexpected restarting.
- Depressurize the system: Ensure the separator vessel and connected components are fully depressurized before opening the assembly.
- Allow the equipment to cool: Follow the service instructions for safe handling of hot components and lubricant.
- Prepare the work area: Keep the replacement element, tools and sealing surfaces clean to avoid introducing contaminants.
- Remove the existing separator: Follow the equipment-specific removal procedure and inspect the removed element for damage or abnormal contamination.
- Inspect the housing and seals: Check the mounting surface, sealing interfaces and oil-return arrangement for damage, blockage or residue.
- Verify the replacement element: Confirm the part reference and ensure that the replacement matches the specified housing and connection arrangement.
- Install the separator correctly: Follow the prescribed instructions for seating, sealing and securing the element.
- Check operation after servicing: Restart the compressor according to the approved procedure and inspect for leakage, abnormal pressure drop or unusual oil carryover.

Technical FAQs
Which compressor models use the 54749247 separator element?
The 54749247 reference is associated with Ingersoll Rand SSR UP5, UP6 and EW5 compressor applications. The exact model and separator arrangement should be checked before selecting a replacement.
What symptoms may indicate a separator problem?
Possible signs include increased differential pressure, abnormal oil carryover or changes in compressor operating conditions. These symptoms can have other causes, so the oil-return arrangement and wider compressor system should also be checked.
Why must the separator housing be depressurized before servicing?
The housing contains compressed air and may contain hot lubricant. Opening it while pressurized can release stored energy and cause serious injury. Follow the equipment’s isolation and depressurization procedure before removing the element.
Can an oil filter be used in place of an air/oil separator?
No. An oil filter removes particulate contaminants from circulating lubricant, while an air/oil separator removes oil droplets from compressed air. The two components serve different flow paths and are not interchangeable.
