Product Overview

The Ingersoll Rand 47704433001 / 23595879 Pre-Filter is a replacement filtration component used in compatible industrial compressed-air systems. As a pre-filtration element, its main purpose is to capture larger particles and contaminants before the compressed air reaches downstream filtration stages or sensitive equipment.

Pre-filters play an important role in multi-stage compressed-air treatment. By removing larger contaminants at an early stage, they can reduce the contaminant load placed on finer filters and help maintain stable airflow through the overall air-treatment system.

The 23595879 is the associated pre-filter part number, while 47704433001 is provided as the related product reference.

With supplied dimensions of 110 × 35 × 100 mm and an approximate weight of 0.15 kg, this compact filter element is suitable for industrial maintenance applications where efficient use of installation space is important.

The pre-filter is a consumable maintenance component and should be replaced when contamination, pressure drop, or the applicable maintenance schedule indicates that the filter element has reached the end of its service life.

Technical Specifications

The stated 110 × 35 × 100 mm dimensions and 0.15 kg weight refer to the supplied product specifications.

Function and Working Principle

The primary function of the 23595879 Pre-Filter is to provide an initial filtration stage for compressed air.

A typical air-treatment arrangement can be represented as:

Air Compressor → Aftercooler → Pre-Filter → Fine Filter → Dryer → Air Receiver → Production Equipment

Compressed air entering the filter housing passes through the pre-filter media. Larger particles and contaminants are captured before the air proceeds to subsequent treatment stages.

This first-stage filtration helps:

• Reduce the particle load on downstream filters
• Protect fine filtration elements
• Improve overall compressed-air cleanliness
• Support stable airflow
• Reduce contamination of downstream equipment

The exact filtration performance depends on the complete filter assembly and system configuration rather than the cartridge alone.

Role in Industrial Compressed-Air Systems

Compressed air generated by industrial compressors can contain contaminants originating from the surrounding environment, compressor operation, piping, storage equipment, and distribution systems.

A pre-filter provides an initial barrier against these contaminants.

In a multi-stage system, the pre-filter works together with finer filtration components:

Pre-Filter → Fine Filter → Dryer → Point-of-Use Filtration

The pre-filter handles the initial contaminant load, while downstream filtration provides more refined air treatment where required.

This arrangement can be particularly beneficial when the compressed-air system supplies:

• Pneumatic control valves
• Air cylinders
• Instrumentation
• Automated machinery
• Air tools
• Packaging equipment
• Production processes

By maintaining cleaner air upstream, the pre-filter contributes to the reliability of the entire compressed-air distribution system.

Importance of Pre-Filter Maintenance

Like other filter elements, a pre-filter gradually collects contaminants during normal operation.

As the filter becomes loaded, airflow resistance can increase. If replacement is delayed for too long, the pressure drop across the filter may become excessive.

Potential symptoms of a heavily loaded pre-filter include:

• Increasing pressure differential
• Reduced downstream airflow
• Lower available system pressure
• Increased compressor energy consumption
• Reduced efficiency of downstream filtration
• Poor pneumatic equipment performance

Regular inspection and timely replacement help maintain the intended airflow and filtration performance.

Where a differential-pressure indicator is installed, it should be used together with the manufacturer’s maintenance requirements to determine when replacement is appropriate.

Industrial Applications

The Ingersoll Rand 47704433001 / 23595879 pre-filter can be used in a range of compressed-air applications.

Manufacturing Automation

Pre-filtration helps protect pneumatic components used in automated production machinery.

Automotive Manufacturing

Compressed air is commonly used for assembly tools, robotic equipment, pneumatic actuators, and production systems.

Packaging Equipment

Clean compressed air supports reliable operation of pneumatic cylinders, valves, and automated packaging machinery.

Process Industries

Industrial process facilities use compressed air for control equipment, instrumentation, and general plant utilities.

General Factory Air Systems

A pre-filter can be installed as part of a central compressed-air treatment system serving multiple production areas.

Installation and System Integration

The 23595879 pre-filter should be installed in its compatible Ingersoll Rand filtration housing.

A typical replacement procedure includes:

1. Stop or isolate the relevant compressed-air system.
2. Completely release pressure from the filter housing.
3. Open the housing according to the applicable service procedure.
4. Remove the used pre-filter.
5. Inspect the housing and sealing surfaces.
6. Install the new filter element correctly.
7. Check seals and replace them when required.
8. Close and secure the filter housing.
9. Restore the compressed-air supply.
10. Check for leakage and abnormal pressure drop.

After installation, technicians should confirm correct airflow and verify that downstream equipment receives the expected air pressure.

Never open a pressurized filter housing.

Compatible System Components

The pre-filter normally operates as part of a larger compressed-air treatment system.

The complete system should be configured according to the required compressed-air quality and application.

Recommended Alternative Models

Filter elements should be matched to the correct housing and filtration requirements. Similar physical dimensions do not automatically guarantee compatibility.

The correct replacement should be confirmed using the original filter part number, filter housing, filtration grade, airflow requirements, and operating pressure.

Technical FAQs

What is Ingersoll Rand 23595879?

It is a pre-filter element designed for compatible compressed-air filtration systems.

What is 47704433001?

47704433001 is the related product reference supplied for the 23595879 pre-filter.

What does a pre-filter do?

A pre-filter provides an initial filtration stage and helps capture larger contaminants before the compressed air reaches finer filters or sensitive equipment.

What are the dimensions?

The supplied dimensions are approximately 110 × 35 × 100 mm.

How much does it weigh?

The supplied weight is approximately 0.15 kg, or 150 grams.

Is the pre-filter reusable?

It is normally treated as a replaceable consumable filter element. Cleaning or reuse should only be performed when specifically permitted by the applicable filter design.

When should the pre-filter be replaced?

Replacement depends on operating conditions, contamination level, pressure differential, service schedule, and the requirements of the complete filtration system.
