Product Overview
The Ingersoll Rand 47556185001 23424922 Coolant Filter is a replacement filtration component for compatible industrial air compressor systems. In oil-injected rotary screw compressors, the coolant circulates through the compression and cooling circuit, where it helps control temperature, lubricate moving parts, and support effective sealing between the rotors. Keeping this fluid clean is important for protecting internal components and maintaining the intended operating condition of the compressor.
During normal operation, coolant can carry fine particles, wear debris, and contaminants introduced through servicing or fluid degradation. The coolant filter captures specified contaminants as the fluid passes through the filtration media. If the filter becomes excessively loaded, flow resistance can increase, potentially affecting coolant circulation and the overall thermal performance of the compressor.
In a compressor operating for extended shifts, the coolant filter is part of routine preventive maintenance rather than a component that should be replaced only after a fault occurs. Its condition and replacement interval depend on the compressor model, coolant specification, operating hours, and service conditions. A filter that fits physically but has the wrong filtration characteristics may not provide the required protection.
The 47556185001 and 23424922 identifiers should be checked against the equipment’s parts documentation before installation. Ingersoll Rand uses different filtration components across compressor families, and coolant filters should not be confused with air filters, oil separators, or compressed-air line filters. Confirming the correct part number helps ensure that the replacement matches the intended coolant circuit and filter housing.

Working Principle
The coolant filter operates as a fluid filtration element within the compressor’s coolant circuit. As the compressor circulates coolant through the system, the fluid passes through the filter media, where specified particles are retained before the coolant continues toward the relevant internal components.
A simplified flow path is:
Coolant Reservoir or Sump → Coolant Filter → Cooling and Lubrication Circuit → Compressor Components
The exact flow arrangement varies by compressor design. In an oil-injected rotary screw compressor, coolant is commonly circulated through the compression chamber and then routed through separation and cooling stages before returning to the operating circuit. The filter’s position within that arrangement determines which contaminants it captures and which components it protects downstream.
As particles accumulate in the media, the pressure drop across the filter may increase. A loaded filter can restrict circulation, particularly when the fluid is cold or the system is operating under demanding conditions. For this reason, maintenance should follow the specified service interval and take account of operating hours and coolant condition.
Replacing the filter does not correct every cause of coolant contamination. Persistent debris, abnormal coolant discoloration, or repeated filter loading may indicate other issues, such as deteriorating fluid, component wear, or contamination introduced during servicing. Those conditions should be investigated rather than addressed solely by installing another filter.
Role in the Compressor Coolant Circuit
The coolant filter supports the fluid-management section of a compatible compressor. It works alongside the coolant reservoir, circulation hardware, heat exchanger, and other components that maintain the required operating temperature and coolant condition.

Installation and Maintenance
- Confirm the part number: Check both 47556185001 and 23424922 against the compressor’s parts list and serial-specific configuration.
- Shut down the compressor: Follow the approved shutdown procedure and allow the system to reach a safe maintenance condition.
- Relieve stored pressure: Verify that the relevant coolant circuit and filter housing are depressurized before opening the assembly.
- Allow the coolant to cool: Hot coolant can cause burns. Wait until the system has cooled sufficiently for safe service.
- Prepare for fluid collection: Use a suitable container and absorbent materials to manage coolant released during filter removal.

- Inspect the filter housing: Check the sealing surface, threads, and adjacent fittings for damage, deposits, or signs of leakage.
- Check the replacement seal: Use the specified sealing arrangement and replace any seal that is damaged or designated for single use.
- Install the new filter: Follow the prescribed installation orientation and tightening method. Do not overtighten the housing or filter connection.

Technical FAQs
What is the difference between a coolant filter and an oil separator?
A coolant filter removes specified particulate contaminants from the circulating fluid. An oil separator has a different purpose: in an oil-injected compressor, it separates coolant droplets from compressed air before the air continues downstream. The two components occupy different positions in the system and cannot be substituted for one another.
Can a coolant filter be replaced without draining the entire compressor system?
That depends on the compressor’s filter-housing arrangement and the prescribed maintenance procedure. Some configurations may allow filter replacement after isolating and depressurizing the relevant section, while others require additional coolant handling. Always follow the procedure for the exact compressor model and prevent contamination from entering the open circuit.
What symptoms may indicate that the coolant filter needs attention?
Potential signs include abnormal pressure differential where monitored, restricted coolant circulation, elevated operating temperature, or visible leakage around the filter housing. These symptoms can also result from other faults, so the filter should be inspected alongside coolant level, cooler condition, thermostatic components, and the wider circulation circuit.
Why must the replacement filter match the compressor model?
The filter must match the housing, sealing arrangement, fluid compatibility, and required filtration characteristics. A component with similar external dimensions may still have different media or flow characteristics. Verify the full part number and the compressor’s approved parts configuration before installation.
