Product Overview

The Ingersoll Rand 47639429001 47571612001 Filter Pad is a replacement filtration component used in industrial compressor equipment. Unlike a conventional cylindrical filter, a filter pad is typically installed as a flat filtration medium within a dedicated frame, panel, or air-handling section.

The filter pad captures airborne dust and particulate matter as air passes through the filtration material. This helps reduce contamination entering the associated equipment and supports cleaner air movement through the system.

For compressor maintenance, the filter pad is normally treated as a serviceable consumable. Correct part-number identification and proper positioning in the filter assembly are important when replacing an existing pad during routine maintenance.

Technical Specifications

Product Features

• Intended for filtration applications in Ingersoll Rand equipment.
• Provides a flat filtration medium for capturing airborne particles.
• Helps reduce dust and particulate contamination entering the associated air path.
• Suitable for routine maintenance and replacement work.
• Supports continued filtration performance when installed correctly.
• Uses identified part numbers for spare-parts matching.
• Suitable for applications where a replaceable filter pad is used instead of a conventional cartridge.

Working Principle

The Filter Pad operates as a passive filtration layer within the equipment’s air path. As air passes through the filter material, suspended dust and other airborne particles are retained by the filtration media.

The filtered air continues downstream while accumulated contaminants remain within the pad. Over time, loading of the filtration material can increase airflow resistance, so filter condition needs to be considered during routine equipment inspection.

Installation position and sealing are also important. If the pad is not correctly seated in its frame or if air can bypass the filtration material, contaminants may pass downstream without being adequately filtered.

Industrial Applications

Installation and Maintenance

1. Verify the Part Number — Confirm that 47639429001 and 47571612001 correspond to the required equipment and filter-pad application.
2. Isolate the Equipment — Shut down the associated equipment and follow the applicable safety and isolation procedure before accessing the filter assembly.
3. Inspect the Existing Pad — Check the removed filter pad for dust loading, deformation, moisture, tears, or other signs of deterioration.
4. Clean the Filter Area — Remove loose dust and contamination from the surrounding frame or housing before installing the replacement pad.
5. Inspect the Retaining Frame — Make sure the frame, clips, guides, or other retaining hardware are not damaged or deformed.
6. Check the Airflow Direction — Confirm the intended airflow path and install the pad in the correct orientation where the equipment design specifies one.
7. Seat the Filter Pad Properly — Position the pad evenly within its frame so that there are no folds, gaps, or unsupported sections.
8. Prevent Air Bypass — Check the edges and retaining arrangement to ensure air cannot easily pass around the filtration material.
9. Avoid Media Damage — Handle the filter pad carefully during installation to prevent tearing, crushing, or contamination of the filtration material.
10. Inspect After Installation — Confirm that the pad remains properly positioned after the filter housing or access panel is secured.
11. Monitor Airflow Conditions — During operation, observe for abnormal airflow restriction or other indications that the filtration section requires attention.
12. Record the Replacement — Document the part number, replacement date, operating conditions, and maintenance observations for future service planning.

Technical FAQs

What is the function of the Ingersoll Rand 47571612001 Filter Pad?

The Filter Pad functions as a passive filtration medium, capturing airborne dust and particulate matter as air passes through the filtration section.

How is a filter pad different from a conventional cartridge filter?

A filter pad is generally a flat sheet or panel of filtration media installed within a frame or housing, while a cartridge filter typically has a dedicated cylindrical or molded structure. The correct replacement type depends on the equipment’s original filtration assembly.

What should be checked before installing a replacement filter pad?

Verify the part number, inspect the retaining frame, clean the surrounding area, and confirm that the replacement pad can be seated evenly without gaps or folds. The filtration area should also be checked for potential air bypass.

When should the filter pad be replaced?

Replacement should be based on the equipment manufacturer’s maintenance requirements and the actual operating environment. Excessive dust loading, visible damage, moisture contamination, or increased airflow resistance are common reasons to inspect or replace the filter pad.
