Product Overview

The Ingersoll Rand 47555210001 23424922 Coolant Filter is identified with the 23424922 replacement filter element used in compatible oil-injected rotary screw air compressors. Its function is to remove contaminants from the circulating compressor oil, helping protect the airend and other components that depend on a clean, properly maintained lubrication supply.

In an oil-injected compressor, coolant oil circulates through the machine to lubricate moving components, seal the compression chambers, and carry away heat generated during compression. As the oil moves through the system, it can collect particles originating from normal component wear, contamination introduced during servicing, and degradation within the oil circuit. The coolant filter captures contaminants before they continue circulating through the equipment.

The 23424922 is identified as an M42 coreless spin-on coolant filter element. It is associated with selected Ingersoll Rand R-series compressors, including configurations in the R90–R160 range, as well as other applicable compressor installations. The exact application depends on the machine configuration and installed filter arrangement.

For a maintenance technician servicing a compressor that operates for extended production shifts, the coolant filter is an important item to inspect and replace according to the applicable service schedule. A loaded filter can restrict oil flow, while an unsuitable replacement may fail to seal correctly or may not provide the required filtration performance.

The filter belongs to the compressor’s lubrication circuit, not the main compressed-air filtration system. It should therefore be distinguished from the inlet air filter, air/oil separator, and cabinet ventilation filter when preparing a maintenance parts list.

• Industrial compressor application: Associated with selected Ingersoll Rand R-series and other compatible compressor configurations.

Working Principle

The 23424922 coolant filter operates as part of the compressor’s oil circulation circuit. Oil passes through the filter media, which retains suspended particles while allowing filtered oil to continue toward the components that require lubrication and cooling.

A simplified oil-flow arrangement is:

Oil Sump → Coolant Filter → Oil Circuit → Airend and Associated Components → Oil Recovery and Return

The actual flow path varies with compressor design. Some systems incorporate additional components, such as an oil cooler and thermostatic valve, which regulate oil temperature and routing.

Consider a compressor supplying a production line throughout a working shift. The circulating oil repeatedly passes through the lubrication system, and contaminants can accumulate over time. The filter captures particles that would otherwise continue through the circuit. As the element loads with contamination, its resistance to flow may increase, making timely maintenance important.

During a filter change, the technician must use the correct replacement element and ensure that the mounting surface and sealing arrangement are in suitable condition. Incorrect seating or a damaged seal can cause oil leakage, while a filter that does not match the intended specification may compromise the lubrication circuit.

The coolant filter does not cool the oil by itself. Heat removal is handled by the compressor’s oil-cooling arrangement, while the filter’s primary purpose is contaminant removal.

Role in the Compressor Lubrication System

The 23424922 is installed within the compressor’s oil circuit, where it helps maintain oil cleanliness before the lubricant reaches components that depend on it.

Industrial Applications

Installation and Maintenance

1. Verify the part reference: Confirm 47555210001 and 23424922 against the existing filter identification and the compressor’s parts configuration.
2. Identify the compressor model: Check the model and serial number to ensure that the replacement matches the installed lubrication circuit.
3. Shut down the compressor: Follow the prescribed shutdown and energy-isolation procedure before starting maintenance.
4. Allow the oil system to cool: Compressor oil and surrounding components may remain hot after shutdown. Wait until they are safe to handle.
5. Relieve pressure as required: Follow the equipment-specific procedure to ensure the relevant oil circuit is in a safe condition before removing the filter.
6. Prepare the service area: Place a suitable collection container beneath the filter and protect nearby components from spilled oil.
7. Remove the existing filter: Use the appropriate removal method and avoid introducing dirt into the exposed filter mounting point.
8. Inspect the mounting surface: Check the filter head, sealing face, and threaded connection for contamination, damage, or remnants of the previous seal.
9. Install the replacement element: Follow the specified installation instructions, including any seal preparation and tightening requirements applicable to the filter.
10. Check the surrounding oil circuit: Inspect nearby connections and components for visible leakage or damage before returning the compressor to service.
11. Verify operation after replacement: Restart the equipment according to the approved procedure and check for oil leakage, abnormal pressure indications, or relevant alarms.
12. Record the maintenance work: Document the installed part number, service date, operating hours, and any abnormal conditions observed during the filter change.

Technical FAQs

What does the 23424922 coolant filter remove from compressor oil?

It captures particulate contaminants carried by the circulating oil. The filter helps maintain oil cleanliness but does not remove every dissolved contaminant or replace the need for correct oil selection and scheduled oil maintenance.

Is the 23424922 the same as an air inlet filter?

No. The 23424922 filters the compressor’s circulating coolant oil. An inlet air filter removes contaminants from incoming air, while an air/oil separator removes entrained oil from compressed air after compression.

Which compressor configurations should be checked before installing this filter?

The 23424922 is associated with selected Ingersoll Rand R-series compressors, including models in the R90–R160 range. The exact model, serial number, and installed filter arrangement should be verified before replacement.

What should be investigated if oil pressure or temperature changes after a filter replacement?

Check the filter reference, sealing arrangement, installation, oil level, and any relevant pressure or temperature indications. If the problem persists, inspect the wider lubrication and cooling circuits rather than assuming that the filter alone is responsible.
