Introduction
The Ingersoll Rand 47545145001 99289894 Minimum Pressure Valve Service Kit is a specialized maintenance combination for compatible New Cobra M90–160 air-cooled rotary screw compressors. The 47545145001 reference identifies an 8,000-hour preventive maintenance package with modification, while 99289894 is the associated minimum pressure valve service kit. The current maintenance listing specifies one 99289894 kit within the package.
The minimum pressure valve is an important control point in an oil-injected screw compressor. Although compact compared with major compressor assemblies, it contributes to the pressure conditions required for effective oil circulation and stable operation. Its condition can therefore influence more than simply the pressure reading at one point in the system.
99289894 is specifically identified for the M90–160 minimum pressure valve application. The available Ingersoll Rand parts catalogue associates the reference with minimum pressure valve 23521297. This application-specific identification is valuable when purchasing service components because minimum pressure valve kits for different compressor sizes can have different internal components and operating characteristics.
As a service kit, 99289894 is intended for maintenance of the valve rather than being treated as a universal replacement valve. This distinction matters when planning repairs. A technician should first establish whether the valve body and related interfaces remain serviceable and then use the appropriate kit in accordance with the applicable service procedure.
The minimum pressure valve also interacts with the compressor's oil-management system. The compressor requires appropriate internal pressure conditions to maintain effective oil circulation, separation, and control. A valve that does not respond correctly can therefore contribute to symptoms elsewhere in the machine.
During scheduled service, technicians should inspect the valve and surrounding connections for contamination, leakage, damaged sealing surfaces, or other signs of abnormal operation. If pressure behavior is outside the expected range, additional diagnostic checks should be performed rather than assuming that the service kit alone will resolve the problem.
The connection between 47545145001 and 99289894 is particularly useful for preventive-maintenance planning. The 8,000-hour package groups several maintenance operations together, while 99289894 identifies the dedicated service reference for the minimum pressure valve. This simplifies purchasing, inventory control, and technician preparation.
The catalogue also demonstrates why compressor-family verification is necessary. 99289894 is associated with the M90–160 application, while separate minimum pressure valve service references are listed for smaller M-series compressor ranges. A similar-looking kit should therefore never be selected solely on physical appearance.
For procurement teams, the exact part number is an important safeguard against incorrect substitutions. Third-party listings may describe 99289894 as a complete minimum pressure valve, while other catalogues identify it as a service or repair kit. The more precise application-oriented description is minimum pressure valve service/repair kit.
Exact dimensions, weight, internal kit contents, seal materials, individual component quantities, and packaging configuration for 99289894 were not sufficiently verified from authoritative current documentation. These values are therefore intentionally not estimated.
When correctly matched to the compressor, 99289894 provides a practical service solution for maintaining the minimum pressure valve during major preventive maintenance. Used as part of the broader 47545145001 program, it supports systematic maintenance of pressure control and contributes to reliable operation of the New Cobra M90–160 compressor platform.
