Product Overview
The Ingersoll Rand 47704435001 23708423 Air-Oil Separator is an industrial separation component designed for use in compatible Ingersoll Rand oil-injected compressor systems. Its primary function is to separate oil from compressed air after the compression process, helping maintain efficient oil circulation while reducing the amount of oil carried into the compressed-air outlet.
In an oil-injected compressor, lubrication oil performs several important functions, including lubrication, cooling, and sealing within the compression system. After compression, the resulting air-oil mixture must be processed so that the majority of the oil can be separated from the compressed air and returned to the lubrication circuit.
The air-oil separator is a critical component in this process. It works as part of the separator vessel or related separation assembly, allowing separated oil to return to the compressor lubrication system while cleaner compressed air continues toward downstream equipment.
The supplied specification identifies 23708423 as the associated part number. The specified outer diameter is 240 mm, with a product weight of approximately 4.9 kg.
Because separator dimensions, sealing arrangements, pressure characteristics, and internal construction can vary between compressor models, the 47704435001 / 23708423 separator should always be matched to the applicable equipment before installation.

Function and Working Principle
The main purpose of the Ingersoll Rand 47704435001 23708423 Air-Oil Separator is to separate lubrication oil from compressed air after the air and oil have been mixed during the compression process.
A simplified process can be represented as:
Ambient Air → Compression Element → Air/Oil Mixture → Separator → Compressed Air Outlet
At the same time, separated oil follows a return path:
Separator → Oil Return Circuit → Compressor Lubrication System
During compression, oil is introduced into the compression system to provide lubrication, cooling, and sealing. This produces a mixture of compressed air and oil.
The separator provides a controlled environment in which oil droplets and aerosols can be separated from the compressed air.
The separated oil can then be returned to the compressor’s lubrication circuit, while the treated compressed air proceeds to the downstream air system.
This separation process is important for several reasons:
- Reduces oil carryover
- Supports oil recovery
- Helps maintain lubrication efficiency
- Protects downstream compressed-air equipment
- Supports compressor performance
- Helps maintain proper oil levels
- Reduces contamination of the compressed-air system
The separator therefore performs a critical function within an oil-injected compressor.
Role in Industrial Compressor Systems
The air-oil separator is one of the key components of an oil-injected rotary screw compressor system.
A typical system may contain:
- Air Filter
- Intake Valve
- Compressor Element
- Oil Injection System
- Air-Oil Separator
- Oil Filter
- Oil Cooler
- Air Cooler
- Minimum Pressure Valve
- Oil Return Line
- Pressure Sensors
- Temperature Sensors
- Controller
- Compressed-Air Outlet
The separator works together with the oil filter and oil-return system.
After the compression element produces an air-oil mixture, the mixture enters the separation system. The separator removes a significant portion of the oil from the compressed air. The recovered oil is returned to the lubrication circuit, while the compressed air continues downstream.
This process allows the compressor to reuse lubrication oil instead of continuously losing it with the compressed-air output.
Industrial Applications
The Ingersoll Rand 47704435001 / 23708423 air-oil separator is intended for compatible industrial compressor applications.
Industrial Manufacturing
Factories rely on compressed air for pneumatic tools, actuators, production equipment, instrumentation, and automated machinery. Stable compressor operation is therefore essential.
Automotive Manufacturing
Automotive production plants use compressed air throughout assembly, painting, tooling, and automation processes. Effective oil separation helps maintain compressed-air quality.
Packaging Equipment
Packaging machinery frequently uses pneumatic cylinders, valves, and actuators. Proper compressor operation helps maintain stable pneumatic performance.
Process Industries
Oil-injected compressors can be used in a wide variety of industrial process applications. Separator maintenance is an important part of compressor reliability.
General Plant Utilities
Compressed air is often treated as a plant utility. A properly maintained separator helps maintain compressor performance and control oil carryover.
Continuous-Duty Compressor Systems
Compressors operating for long periods place significant demands on filtration and separation components. Regular separator inspection and replacement can therefore be an important part of preventive maintenance.
Installation and Maintenance
Correct installation of the 47704435001 / 23708423 Air-Oil Separator is critical because the separator operates within a pressurized compressor system.
Before replacement, maintenance personnel should verify:
- Compressor model
- Correct separator part number
- Separator dimensions
- Outer diameter
- Sealing arrangement
- Separator housing
- Gasket or O-ring condition
- Oil condition
- Separator vessel condition
- Maintenance interval
Basic Replacement Procedure
- Shut down the compressor according to the approved maintenance procedure.
- Isolate the compressor from electrical and pneumatic energy sources.
- Allow the equipment to cool to a safe maintenance temperature.
- Fully relieve applicable internal pressure.
- Verify that the separator vessel is safe to open.
- Access the air-oil separator assembly.
- Remove the existing separator according to the equipment maintenance procedure.
- Inspect the separator housing.
- Clean the sealing surfaces as required.
- Inspect gaskets, O-rings, fittings, and related sealing components.
- Compare the replacement separator with the removed component.
- Install the new 47704435001 / 23708423 separator correctly.
- Ensure that all sealing components are correctly positioned.
- Secure the separator according to the equipment specifications.
- Reconnect the oil-return and related connections.
- Restore the equipment to service.
- Start the compressor under controlled conditions.
- Check for oil or air leakage.
- Monitor operating pressure and temperature.
- Check oil carryover and compressor operating condition.
- Record the maintenance activity.
Because separator assemblies operate under pressure, maintenance should only be performed after the equipment has been properly shut down, isolated, and depressurized.
Air-Oil Separator Maintenance Considerations
Separator performance can gradually change as the component accumulates contamination or becomes restricted.
Maintenance personnel should monitor:
- Separator differential pressure
- Oil carryover
- Compressor operating pressure
- Oil consumption
- Oil level
- Compressor temperature
- Separator age
- Equipment operating hours
- Abnormal pressure behavior
An increase in differential pressure may indicate that the separator is becoming restricted.
Excessive oil carryover can also indicate a problem with the separator or another part of the compressor system.
However, oil carryover should not automatically be attributed to a defective separator. Other possible causes can include:
- Incorrect oil level
- Blocked oil-return line
- Damaged seals
- Incorrect operating conditions
- Contaminated oil
- Compressor-system problems
- Incorrect separator installation
A complete system diagnosis is therefore recommended when abnormal oil carryover occurs.
