Introduction
The Ingersoll Rand 47550996001 47548442001 Intake Valve Service Kit is a dedicated maintenance combination for compatible New Cobra M90–160 VSD compressor applications. The first reference identifies the overall 8,000-hour water-cooled preventive maintenance package, while the second identifies the intake-valve service kit associated with that maintenance event. A published M90–160 VSD parts listing specifies one 47548442001 kit under 47550996001.
The intake valve is an important control component in an oil-injected rotary screw compressor. It regulates the air entering the airend and works with the compressor control system to manage loading and unloading. Reliable valve movement is therefore essential to predictable compressor response and stable operation.
For the New Cobra 90–160 / M90–160 VSD platform, 47548442001 provides a clear service reference for intake-valve maintenance. The available parts catalogue identifies it as an intake valve maintenance kit, while the broader maintenance listing places it directly within the 8,000-hour service configuration.
Using a dedicated service kit during planned maintenance can help address wear-sensitive valve components before deterioration affects compressor control. Depending on the service procedure and machine configuration, maintenance may involve inspection, cleaning, renewal of seals or other internal components, and verification of valve movement.
The 47550996001 package also covers several other important compressor systems. The documented M90–160 VSD configuration includes the 24172215 air filter, two 39911631 coolant filter elements, 54509427 separator, 99289894 minimum pressure valve service kit, 47545136001 temperature-control valve kit, 47545143001 water-cooler seal kit, and 39218193 motor grease.
This combination makes the kit particularly relevant for coordinated major-service planning. Instead of treating intake-valve work as an isolated repair, maintenance teams can incorporate valve inspection and renewal into the same scheduled shutdown used for filtration, lubrication, separation, and pressure-control maintenance.
It is important, however, to distinguish 47548442001 from other intake-valve references. For example, 47545138001 is described as an intake valve service kit with modification, while 47548442001 is the standard intake-valve service reference listed for the 47550996001 M90–160 VSD configuration. These references should not be substituted solely because they have similar descriptions.
For purchasing and maintenance records, retaining both the 47550996001 kit number and 47548442001 component reference improves traceability. Before installation, the compressor model and serial number should be checked against the applicable parts list to ensure that the correct intake-valve configuration and service procedure are being used.
