Product Overview
The Ingersoll Rand 47704432001 24900433 Oil Filter is an important maintenance component used in compatible oil-injected industrial air compressor systems. The oil filter is responsible for removing contaminants and particulate matter from the compressor lubrication circuit before the oil returns to critical internal components.
In an oil-injected compressor, lubricating oil performs several important functions. It provides lubrication for moving components, helps seal internal clearances, transfers heat away from operating components, and supports reliable compressor performance. Because the oil continuously circulates through the system, contamination must be controlled effectively.
The oil filter helps prevent contaminants from circulating through the compressor oil circuit. A properly maintained filter can help protect bearings, seals, the compression element, and other oil-lubricated components from premature wear.
The supplied product information identifies the component as an Ingersoll Rand 47704432001 24900433 Oil Filter, with dimensions of 208 × 50 × 95 mm and a weight of 1.36 kg.

Oil Filter
The filter captures contaminants suspended in the compressor oil before the oil reaches sensitive internal components.
Contaminants can include:
- Fine particulate matter
- Wear particles
- Degraded oil deposits
- Carbon-like deposits
- Foreign material
- Contamination introduced during maintenance
The filtration process helps maintain cleaner oil and supports reliable lubrication.
Why the Oil Filter Is Important
The compressor oil system operates continuously during normal compressor operation. Contaminated oil can accelerate wear on internal components.
An effective oil filter helps:
- Reduce particulate circulation
- Protect oil-lubricated components
- Maintain oil cleanliness
- Support stable lubrication
- Reduce internal wear
- Improve compressor reliability
- Support longer component service life
The oil filter should therefore be treated as a critical preventive-maintenance component rather than simply a replaceable consumable.
Relationship Between Oil Filtration and Compressor Performance
Oil filtration can influence several compressor operating characteristics.
A clean filter generally allows the lubrication system to maintain appropriate oil flow.
As contamination accumulates, filter resistance may increase. This can produce increased pressure differential across the filter and potentially affect oil circulation.
If filtration is neglected for too long, the compressor may experience:
- Reduced lubrication efficiency
- Increased pressure drop
- Increased oil temperature
- Abnormal operating conditions
- Increased component wear
- Lubrication-related alarms
For this reason, oil-filter maintenance should be included in the compressor’s preventive-maintenance program.

Signs That the Oil Filter Requires Attention
Common warning signs include:
Increased Differential Pressure
A rise in pressure drop can indicate filter restriction.
Reduced Oil Pressure
A restricted oil circuit can contribute to abnormal oil pressure.
Increased Oil Temperature
Reduced oil flow can affect heat transfer.
Lubrication Problems
Insufficient or restricted oil flow can affect compressor components.
Frequent Oil-Related Alarms
Repeated alarms should trigger a complete lubrication-system inspection.
Excessive Filter Contamination
Unusually dirty filters can indicate an underlying compressor problem.
Common Installation Mistakes
Using an Incorrect Filter
A filter that physically fits may not necessarily have the correct filtration and flow characteristics.
Damaging the Seal
A damaged or incorrectly positioned seal can cause oil leakage.
Cross-Threading
Incorrect filter installation can damage the mounting connection.
Over-Tightening
Excessive tightening can damage the filter or mounting assembly.
Dirty Installation Area
Contamination introduced into the oil circuit can cause additional problems.
Ignoring Oil Level
Incorrect oil level can produce symptoms that resemble filter problems.
Failing to Check for Leakage
Always inspect the filter area after startup.
Failing to Investigate Rapid Contamination
A filter that becomes contaminated unusually quickly may indicate excessive internal wear or oil degradation.
Oil Filter and Compressor Reliability
The oil filter contributes to the cleanliness of the compressor lubrication system.
Clean oil helps reduce the circulation of abrasive particles through critical components.
This is particularly important for:
- Bearings
- Sealing components
- Compression elements
- Oil passages
- Oil-control components
Maintaining appropriate oil cleanliness can therefore contribute to compressor reliability and predictable maintenance intervals.
Relationship Between Oil Filter and Oil Cooler
The oil filter and oil cooler perform different functions but operate within the same lubrication system.
The oil filter primarily controls particulate contamination.
The oil cooler primarily removes heat from compressor oil.
A restricted filter can affect oil flow, while a contaminated cooler can increase oil temperature.
If compressor temperature becomes abnormal, both components should be evaluated rather than replacing only one component without diagnosis.
Relationship Between Oil Filter and Temperature Control Valve
The temperature control valve regulates oil flow through the cooling circuit, while the oil filter removes contaminants from circulating oil.
A malfunctioning temperature control valve can cause abnormal oil temperature, while a restricted oil filter can cause excessive resistance in the oil circuit.
These components should therefore be considered together when troubleshooting:
- High oil temperature
- Low oil pressure
- Lubrication problems
- Compressor overheating
