Introduction
The Ingersoll Rand 47545141001 39911631 Coolant Filter Element is a key filtration component within the 16,000-hour preventive maintenance program for compatible New Cobra M90–160 water-cooled rotary screw compressors. The 47545141001 reference identifies the major maintenance package, while 39911631 is specified as the coolant filter element supplied in a quantity of two.
Filtration is fundamental to the reliability of an oil-injected screw compressor. The compressor coolant/lubricant performs several important functions, including lubrication, cooling, and sealing. Maintaining its cleanliness helps protect the components that depend on stable lubricant circulation.
During compressor operation, contaminants can accumulate in the lubricant circuit through normal wear, environmental exposure, maintenance activity, and other operating factors. The coolant filter provides a controlled filtration point for removing particulate contamination from the circulating fluid.
The 39911631 reference is particularly relevant to larger New Cobra compressor maintenance programs. Current parts data lists it for the New Cobra M90–160 kW family and specifies two elements in the 47545141001 16,000-hour water-cooled maintenance package.
Replacing both specified elements during scheduled service helps restore the intended filtration condition of the system. It also allows technicians to inspect the filter housing, seals, connections, and surrounding components for contamination or abnormal conditions.
The filter should not be selected solely by external appearance or approximate dimensions. Ingersoll Rand uses multiple filter references across different compressor generations and capacity ranges. A component that appears physically similar may have different filtration characteristics, sealing arrangements, flow capacity, or application requirements.
The term “coolant filter” can also cause confusion in water-cooled compressor applications. The 47545141001 package is classified as water-cooled because the compressor uses a water-based heat-removal arrangement, but 39911631 is identified as a coolant filter element within the compressor maintenance system. It should not automatically be interpreted as a filter for the external cooling-water circuit.
The broader 47545141001 maintenance package also includes 24172215 air filters, 39218193 motor grease, 54509427 separator elements, 99289894 minimum-pressure valve service kits, 47545136001 temperature-sensing valve maintenance kits, 47545138001 modified inlet-valve service kits, 47545140001 air-cooling hose service kits, and 47545143001 water-cooler seal maintenance kits.
This combination illustrates the comprehensive nature of a major scheduled service. Filtration, lubrication, pressure regulation, temperature control, intake regulation, and cooling-system integrity can all be addressed during the same planned maintenance period.
For maintenance teams, replacing 39911631 at the specified service interval provides a straightforward way to maintain lubricant filtration and improve service traceability. Using the exact part number and specified quantity also helps prevent procurement errors when multiple compressor models are maintained at the same facility.
Filter condition should also be considered when troubleshooting compressor operation. A filter-related issue may present alongside other symptoms, but reduced compressor performance or abnormal temperature should not automatically be attributed to the filter. Proper diagnostics should evaluate the complete lubrication and cooling system.
Exact OEM dimensions, filtration efficiency, media construction, pressure-drop limits, package dimensions, and weight for the current 39911631 configuration were not sufficiently verified from authoritative current documentation. These specifications are therefore intentionally not estimated.
For industrial operators, the 39911631 coolant filter element provides an important contamination-control function within the 47545141001 16,000-hour maintenance program. Correct application matching and replacement according to the applicable Ingersoll Rand service requirements can support dependable lubricant circulation and long-term compressor reliability.
