Product Overview
The Ingersoll Rand 47627051001 54749247 Air/Oil Separator is a replacement separation component used in compatible oil-injected rotary screw air compressors. Its primary function is to remove entrained lubricant from compressed air before the air leaves the compressor’s separation system. The recovered oil returns to the lubricant circuit, while the separated air continues toward downstream equipment.
During compression, oil mixes with incoming air to provide rotor sealing, lubrication, and heat removal. This produces an air/oil mixture that must pass through the separation stage before the compressed air can be delivered. The separator element captures oil droplets and fine oil mist, allowing the collected lubricant to drain back into the compressor’s oil reservoir.
Part number 54749247 is associated with Ingersoll Rand SSR UP5, UP6, and EW5 compressor families in available parts references. It is listed for selected units in the 15–50 hp range, with the precise application depending on the compressor model and configuration. Some listed machines use two separator cartridges, so the required quantity depends on the installed separator vessel arrangement.
The separator’s performance affects both compressed-air quality and compressor energy consumption. As the media accumulates contaminants, resistance to airflow can increase, raising the pressure drop across the separation stage. Excessive restriction may force the compressor to work harder to maintain delivery pressure, while damaged media or defective seals can allow excessive oil carryover into the downstream air circuit.
The 54749247 separator is a cartridge-style component used within the separator tank. Its mounting and sealing arrangements must match the intended assembly. Correct installation helps maintain the designed airflow path and prevents compressed air from bypassing the separation media.
Routine servicing should include inspection of the separator vessel, sealing surfaces, and oil-return arrangement. If the removed element shows unusual deposits, damage, or evidence of excessive oil loading, the surrounding system should also be checked. Replacing the separator without addressing a blocked oil-return path or another operating issue may not resolve recurring oil carryover.
The Ingersoll Rand 47627051001 54749247 Air/Oil Separator supports the separation process in compatible compressor installations. Proper part selection, correct installation, and maintenance in accordance with the equipment’s service requirements help preserve separation efficiency and normal compressor operation.

Working Principle
The Ingersoll Rand 54749247 Air/Oil Separator uses coalescing filtration to remove lubricant from compressed air. In an oil-injected rotary screw compressor, the air/oil mixture produced by the compression element enters the separator vessel, where the separation process removes most of the entrained lubricant before the air proceeds downstream.
Compression Element → Separator Tank → Air/Oil Separator → Downstream Air Circuit
As the mixture enters the separation system, larger quantities of oil may separate from the air through the vessel’s internal flow arrangement. The remaining oil mist passes through the separator media. Fine droplets collect on the media fibers and combine into larger droplets, which then drain through the designated recovery path.
The recovered oil returns to the compressor’s lubricant reservoir or circulation circuit, depending on the system design. The separated air leaves the vessel and continues through the downstream circuit.
During operation, particles and other contaminants can accumulate in the media. This may gradually increase the pressure difference across the separator. When the pressure drop becomes excessive, the compressor may require more energy to maintain its operating conditions, and overall system efficiency can decline.
Oil carryover can also result from damaged media, incorrect installation, defective seals, or a restricted oil-return path. These conditions require different corrective actions, so inspection should cover the complete separation assembly rather than the cartridge alone.
The separator must be installed in the specified position with its sealing components correctly seated. Gaps around the element can allow air to bypass the media, while an obstructed recovery path may prevent collected oil from returning properly.
Following replacement, the compressor should be returned to service using the applicable maintenance procedure. Technicians should check for leakage, review available pressure-drop indications, and observe whether oil carryover remains within the equipment’s specified operating requirements.
Role in the Compressor Air and Lubricant Circuit
The 54749247 Air/Oil Separator is installed in the separation stage of compatible Ingersoll Rand oil-injected rotary screw compressors. It separates lubricant from the compressed-air stream while supporting the return of recovered oil to the lubrication circuit.
Compression Element → Separator Vessel → Separator Cartridge → Downstream Air Circuit
Collected Lubricant → Oil-Return Path → Lubricant Reservoir

Installation and Maintenance
- Isolate the compressor: Stop the equipment and follow the prescribed lockout procedure before starting maintenance.
- Depressurize the separator tank: Confirm that the vessel and associated piping are safely depressurized before opening the assembly.
- Allow the system to cool: Ensure that the separator vessel and lubricant have reached a safe condition for servicing.
- Confirm the separator application: Check that part 54749247 corresponds to the compressor’s installed separation arrangement.
- Open the separator assembly: Follow the equipment-specific instructions and protect the vessel cover, fasteners, and sealing surfaces from damage.
- Remove the old cartridge: Extract the used separator carefully to prevent accumulated oil and contaminants from entering adjacent passages.
- Inspect the vessel interior: Check for deposits, corrosion, damaged sealing surfaces, or other conditions that may affect the replacement element.
- Check the oil-return path: Inspect accessible recovery components for blockage or damage and address any issues according to the maintenance procedure.
- Prepare the sealing surfaces: Clean the relevant contact areas and replace required sealing components as specified for the assembly.
- Install the replacement separator: Position the cartridge correctly and ensure that the element and seals are seated in their intended locations.
- Restore and test the compressor: Reassemble the vessel, return the equipment to service under the approved procedure, and check for leakage and abnormal operating indications.
- Record the service results: Document the replacement date, operating hours, and any unusual pressure-drop or oil-carryover observations.
If oil carryover remains excessive after replacement, investigate the sealing arrangement, oil-return path, lubricant condition, and operating conditions. Replacing the cartridge alone may not resolve an underlying system fault.

Technical FAQs
Why may a compressor require two 54749247 separator cartridges?
Some compatible compressor configurations use two separator cartridges in the separator tank. The required quantity depends on the specific compressor model and installed vessel arrangement, so replacement quantities should follow the applicable equipment parts information.
How does a loaded separator affect compressor energy consumption?
As contaminants accumulate in the media, resistance to airflow may increase. The resulting pressure drop can make the compressor work harder to maintain its required delivery conditions, increasing energy consumption. The element should be assessed against the equipment’s specified service criteria.
What should be inspected if oil carryover continues after installing a new separator?
Check that the cartridge and seals are correctly installed, then inspect the oil-return path and relevant operating conditions. Damage to the separator assembly or problems elsewhere in the lubricant circuit may also contribute to excessive oil carryover.
Is the 54749247 separator suitable for every Ingersoll Rand rotary screw compressor?
No. The part is associated with particular SSR UP5, UP6, and EW5 applications, but compatibility depends on the individual compressor configuration. The specified part reference and separator arrangement should be checked before installation.
