Introduction
The Ingersoll Rand 47588562001 / 23708423 Air/Oil Separator Maintenance Kit combines a scheduled service reference with a specific separator element used in compatible rotary screw compressor systems.
Ingersoll Rand parts listings identify 47588562001 as a 4,000-hour preventive maintenance kit, placing it within a broader scheduled-maintenance family that includes 2,000-hour and 8,000-hour service kits.
The independently documented 23708423 is an air/oil separator element. It is designed to remove oil mist from compressed air after the compression process, helping return separated lubricant to the compressor and reduce oil contamination in the downstream air stream.
Unlike an intake filter or spin-on oil filter, the 23708423 element is a drop-in separator located inside the sump tank. This makes correct installation and sealing particularly important. Before fitting a replacement, the separator-tank sealing surface should be cleaned and inspected to ensure the new element seats correctly.
The separator's condition directly influences compressed-air quality and compressor operating efficiency. When the element becomes degraded or excessively restricted, pressure drop across the separator can increase, while deteriorating separation performance can allow more oil vapor or aerosol to leave the compressor with the discharge air.
Application records associate 23708423 with several established Ingersoll Rand R and RS-series platforms, including R55i/R75i and RS45i/RS55i/RS75i variants. Because these product families were produced in multiple configurations, the compressor serial number remains an important part of final part-number verification.
Available dimensional records are not completely consistent across suppliers. One filter-supply listing reports approximately 9.370 inches outside diameter and 10.910 inches height, while another aftermarket technical record gives substantially different overall dimensions. For this reason, the supplier dimensions should be treated as identification data rather than an authoritative OEM engineering specification.
A separate supplier lists the replacement element at approximately 14 lb, but this is supplier-specific data rather than a verified Ingersoll Rand engineering weight. The complete 47588562001 kit's dimensions and weight are not reliably documented in the available public records.
During separator replacement, technicians should also inspect the separator tank for foreign objects, verify the condition of the sealing surfaces, and follow the applicable compressor service procedure. Supplier service guidance specifically recommends changing the compressor oil, oil filter, and air filter element when replacing this separator in applicable machines.
The two supplied references are treated as one product listing as requested. Public documentation independently verifies 47588562001 as a 4,000-hour preventive-maintenance kit and 23708423 as an air/oil separator element. The available public records do not independently establish the complete bill of materials inside kit 47588562001, so each reference retains its respective technical identity.
