Introduction
The Ingersoll Rand 47556402001 23429822 Water-Cooled Preventive Maintenance Kit with Modification combination covers the primary intake-air filtration portion of a modified 8,000-hour major-service program for the R90–110 I platform. The service-parts listing identifies 47556402001 as the 8,000-hour water-cooled package with modification and specifies one 23429822 air-filter element.
Clean intake air is fundamental to reliable rotary screw compressor operation. Ambient air can contain dust, fibers, and other particulate contaminants, so the primary air filter provides an important barrier before those contaminants reach the compressor's internal air path.
The 23429822 element is a well-defined R90/R110 component. Current application data lists it across R90/R110 I, N, IE, and NE configurations within stated serial-number ranges, while published dimensions are approximately 490 mm body height, 530 mm total height, 267 mm outer diameter, and 175 mm inner diameter.
The important feature of 47556402001 is not a different air filter. The published service table shows that the modified package retains 23429822 but changes the inlet-valve service component to 47553881001, identified as an inlet-valve service kit with modification. This makes modification status an important purchasing criterion.
The package also includes one 23424922 coolant filter, one 23497001 pre-filter, one 23545841 separator element, one 23531577 minimum-pressure-valve kit, one 47552954001 temperature-sensing valve kit, one 47555464001 water-cooler seal kit, and one 39218193 motor grease. This confirms that 47556402001 is a comprehensive major-maintenance package rather than an air-filter-only service.
During air-filter replacement, the filter housing and sealing surfaces should be inspected for dust deposits, damage, or evidence of bypass. A correctly sized element can still fail to protect the compressor if it is improperly seated or if the housing seal is damaged.
The compressor environment also affects filter loading. Published information identifies 23388275 as a denser-media, high-dust counterpart for the same general R90/R110 housing. The standard 23429822 should therefore be retained where it is the specified element, while higher-dust applications should be evaluated according to the applicable compressor recommendation.
The modified service package should not be confused with the standard water-cooled 8,000-hour package. Because the modification changes the inlet-valve service requirement, using the wrong major-service kit could result in installing a service kit that does not match the compressor's current configuration.
For maintenance planners, the pair of numbers provides useful traceability: 47556402001 identifies the modified 8,000-hour water-cooled service event, while 23429822 identifies the primary air-filter component.
For purchasing teams, the compressor's serial number and modification history should accompany the kit number. This is especially important where standard and modified 8,000-hour packages are both present in the parts catalog.
The primary air filter should also be considered together with the pre-filter 23497001. The two components perform different filtration functions and should not be treated as interchangeable. The published modified package includes both components.
Exact current package dimensions, kit weight, detailed filter-media engineering characteristics, and complete serial-number application coverage for every 47556402001 revision were not sufficiently verified from authoritative documentation. Those values are therefore intentionally not estimated.
For industrial compressor operators and maintenance professionals, 47556402001 and 23429822 provide a clear reference for primary air filtration within the modified 8,000-hour water-cooled R90–110 maintenance program. Correct package selection, modification-status verification, and proper filter installation can help maintain clean intake air and support dependable compressor operation.
