Introduction
The Ingersoll Rand 47704435001 / 23708423 Air/Oil Separator Element is a critical filtration component within compatible oil-flooded rotary screw compressor systems. Its primary role is to separate entrained compressor lubricant from compressed air after the compression process.
During normal operation, oil is introduced into the compression chamber to provide cooling, sealing, and lubrication. Some of that lubricant becomes suspended in the compressed-air stream. The separator element coalesces the oil aerosol and allows the recovered lubricant to return through the oil-return system while the compressed air continues toward the outlet.
Effective separation is important for more than air cleanliness. It also helps control lubricant consumption, maintain suitable separator pressure drop, and protect downstream air-treatment equipment from excessive oil contamination.
For maintenance teams, timely separator replacement is a key part of compressor service. A separator operating beyond its intended condition can gradually increase differential pressure or oil carryover, while the correct replacement element helps restore the intended balance between separation performance and airflow.

Technical FAQs
1. What is the main function of the Ingersoll Rand 47704435001 / 23708423?
The product is an air/oil separator element designed to remove entrained oil from compressed air inside compatible oil-flooded rotary screw compressors.
2. Why is oil separation necessary in an oil-flooded rotary screw compressor?
Lubricant is introduced into the compression process for sealing, cooling, and lubrication. The separator removes most of the entrained lubricant from the compressed-air stream so that the oil can be recovered and returned to the compressor's lubrication circuit.
3. What can happen when the separator element becomes restricted?
A restricted separator can increase differential pressure across the element. Excessive pressure drop may reduce compressor efficiency and can contribute to abnormal operating conditions.
4. What happens when an air/oil separator is no longer separating efficiently?
Reduced separation efficiency can increase oil carryover into the compressed-air outlet. This may increase lubricant consumption and place additional contamination on downstream air-treatment equipment.
5. Can high oil carryover always be attributed to the separator?
No. Excessive oil carryover can also result from incorrect lubricant level, faulty oil-return components, operating conditions, or other compressor-system problems. Proper troubleshooting should evaluate the complete oil-separation circuit.
6. Does the separator element affect compressed-air quality?
Yes. The separator is an important internal component for controlling lubricant carryover. However, it should not be considered a substitute for downstream compressed-air treatment where specific air-quality classes are required.
7. How does the oil-return system work with the separator?
Oil separated from the compressed-air stream collects within the separator system and is returned to the compressor through an oil-return circuit. Proper operation of both the separator and return system is required for effective lubricant recovery.
8. When should an air/oil separator be replaced?
Replacement should follow the compressor's applicable maintenance schedule and operating conditions. Earlier service may be appropriate when differential pressure increases, oil carryover becomes abnormal, or inspection indicates deterioration.
9. Can an incorrect separator element cause compressor problems?
Yes. An element with incorrect dimensions, filtration characteristics, or flow resistance may affect separation efficiency and pressure drop. The replacement should therefore match the specified compressor configuration.
10. What should be verified before ordering 47704435001 / 23708423?
The compressor model, serial number, existing separator part number, separator vessel configuration, and applicable service documentation should be verified. This ensures the element is suitable for the particular compressor installation.
