Product Overview
The Ingersoll Rand 47555204001 23429822 Air Filter is an intake filtration component for compatible rotary screw air compressors. It removes airborne dust, dirt, and other particulate contaminants before they enter the compressor’s air end. Maintaining clean intake air helps protect internal compression components, preserve airflow, and reduce the risk of premature wear caused by abrasive particles.
In a rotary screw compressor, incoming air passes through the intake filter before reaching the compression chamber. The filter media captures contaminants while allowing air to flow toward the screw elements. As the compressor operates, the element gradually accumulates dust, and its resistance to airflow can increase. Regular inspection and replacement help maintain the intended intake conditions.
The 23429822 reference is associated with selected Ingersoll Rand R90 and R110 compressor configurations, including certain versions identified by model and serial number. The 47555204001 reference should be checked alongside the compressor identification and installed filter assembly to confirm that the replacement matches the equipment.
An intake filter affects more than the cleanliness of incoming air. A restricted element can reduce the available intake flow and increase the pressure difference across the filter. Depending on the compressor’s control arrangement and operating conditions, this may affect air delivery and operating efficiency. A damaged or incorrectly seated element can allow contaminants to bypass the filter and reach the air end.
For example, a compressor operating in a metalworking plant may draw air containing fine dust from machining and material-handling activities. The intake filter helps prevent these particles from entering the screw compression stage, where contamination can contribute to wear and interfere with normal equipment operation.
When replacing the 23429822 element, technicians should inspect the filter housing, sealing surfaces, and intake ducting as well as the filter itself. A correctly matched replacement cannot compensate for a damaged seal, a distorted housing, or an intake connection that allows unfiltered air to enter the compressor.

Working Principle
The 23429822 air filter operates by passing incoming air through a porous filtration medium that retains particulate contaminants. The filter is installed upstream of the screw air end, where it forms the first filtration barrier against dust and other airborne debris entering the compression process.
Ambient Air → Intake Filter Element → Inlet Valve → Screw Air End → Oil Separation Circuit → Compressed Air System
As air passes through the filter media, particles are captured within or on the surface of the material. Cleaned air continues toward the compressor inlet, while accumulated contaminants remain in the element until it is cleaned or replaced according to the applicable maintenance procedure.
The filter’s resistance to airflow changes as dust accumulates. A clean element generally presents less resistance than a heavily loaded one. When restriction becomes excessive, the compressor may experience reduced intake capacity or increased operating losses, depending on the equipment’s control system and operating conditions.
The filtration process also depends on the integrity of the complete intake assembly. If the element is incorrectly seated, the housing seal is damaged, or an intake connection leaks downstream of the filter, unfiltered air may enter the air end. This bypass contamination can undermine the protection provided by the filter media itself.
The 23429822 element should therefore be selected and installed according to the compressor’s specified configuration. Filter dimensions alone are not sufficient to establish compatibility because sealing geometry, media characteristics, airflow requirements, and housing design also affect suitability.
During maintenance, the technician should examine the removed element for uneven dust loading, damage, deformation, or signs of moisture contamination. The housing and intake ducting should also be inspected before a new element is fitted. After installation, the filter must seat correctly and the intake assembly must be closed securely to prevent bypass leakage.
Role in an Ingersoll Rand Compressor Intake System
The 23429822 air filter is positioned at the beginning of the compressor’s airflow path. Its function is to reduce particulate contamination before air reaches the inlet valve and screw compression elements.

Technical FAQs
Which compressor configurations use the 23429822 air filter?
The part is associated with selected Ingersoll Rand R90 and R110 configurations, including specific model and serial-number ranges. Confirm the compressor identification and installed filter assembly before selecting the replacement.
How does intake filter restriction affect a rotary screw compressor?
As dust accumulates, airflow resistance can increase. Excessive restriction may reduce available intake flow or increase operating losses, depending on the compressor’s control arrangement. Filter condition should be evaluated using the applicable service limits and restriction indications where fitted.
Can a new air filter solve excessive dust contamination inside the compressor?
Not necessarily. Contamination may result from an incorrectly seated filter, damaged housing seals, leaking intake connections, or maintenance practices that allow dust to enter the clean side. Inspect the complete intake assembly rather than replacing the element alone.
What should be checked when replacing the 23429822 filter?
Confirm the part reference, inspect the housing and sealing surfaces, check the replacement media for damage, and ensure that the element seats correctly. After installation, verify that the intake assembly is secured and that any available restriction indication responds as expected.
