Introduction
The Ingersoll Rand 47704436001 / 23595879 Pre-Filter Pad is an intake-air pre-filtration component designed for compatible Ingersoll Rand rotary screw compressor systems.
A compressor's intake filter system has a direct role in protecting the airend from contamination. In industrial environments, ambient air can carry dust, fibers, dirt, and other particulate matter. Allowing excessive contamination into the compressor can increase the load on the primary filter and potentially affect the condition of internal components.
The 23595879 is identified as a pre-filter pad with a 10 × 425 × 740 mm configuration. Parts listings associate the component with the air-filter system used on R55N, R75N, R55I, and R75I compressor configurations.
Its role is straightforward but valuable: provide an additional filtration barrier before the primary intake filter. For compressors operating in dusty production areas or other contaminated environments, maintaining this upstream filtration stage can help keep the main air filter working under more favorable conditions.

Technical FAQs
1. What is the primary function of Ingersoll Rand 47704436001 / 23595879?
It is a pre-filter pad designed to provide an initial stage of filtration for compressor intake air. Its purpose is to intercept airborne contamination before it reaches the primary air-filter element.
2. What type of component is 23595879?
The 23595879 is identified as a Pre-Filter Pad, with the parts description specifying “PAD, PRE-FILTER (10 X 425 X 740).”
3. Which Ingersoll Rand compressors are associated with 23595879?
Parts information lists 23595879 within the air-filter system for R55N, R75N, R55I, and R75I compressor configurations.
4. How does a pre-filter protect the primary air filter?
The pre-filter captures a portion of the larger airborne contamination before the intake air reaches the main filter. This reduces the contaminant load on the primary filter and can help maintain its filtration performance.
5. Is 23595879 the same as the main compressor air filter?
No. It is a pre-filter pad, not the primary air-filter element. It works as an upstream filtration stage within the intake system.
6. What types of contaminants can load the pre-filter?
Dust, fibers, dirt, workshop particles, outdoor particulate matter, and other airborne debris can accumulate in the filter material. The rate of loading depends heavily on the compressor's operating environment.
7. Can excessive pre-filter loading affect compressor airflow?
Yes. As contamination builds up, airflow resistance can increase. If restriction becomes excessive, intake performance can be affected, so the pre-filter should be inspected and serviced according to the applicable maintenance procedure.
8. Can the pre-filter be cleaned instead of replaced?
Whether cleaning is permitted depends on the applicable service procedure and the condition of the filter material. A damaged, permanently contaminated, or deteriorated pad should be replaced rather than returned to service.
9. Why is pre-filtration particularly useful in dusty environments?
High levels of airborne particulate matter can quickly load a primary compressor air filter. An upstream pre-filter provides an additional barrier and helps reduce the amount of larger contamination reaching the main filtration stage.
10. What should be verified before ordering 47704436001 / 23595879?
The compressor model, serial number, intake arrangement, existing pre-filter part number, and applicable parts documentation should be checked. The listed 10 × 425 × 740 mm configuration should also match the installed filter arrangement.
