Technical FAQs

1. What is the purpose of the Ingersoll Rand 47629379001 / 39911631 combination?

It combines a scheduled maintenance kit with an OEM oil filter element to maintain clean lubricant circulation and protect compressor components.

2. What does the 39911631 oil filter do?

The 39911631 filters particles and debris from compressor oil before the lubricant returns to the compression system, helping maintain clean oil flow to the air end and oil cooler.

3. Why is oil filtration important in a rotary screw compressor?

Clean oil reduces friction, supports cooling, protects bearings and rotors, and helps maintain compressor efficiency.

4. Which compressors use the 39911631 filter?

The filter is used on selected Ingersoll Rand compressor models, including certain EP75, EP100, HP, XP, HXP, EPE, and Nirvana configurations. Compatibility should be verified by model and serial number.

5. How often should the 39911631 oil filter be replaced?

A common service recommendation is approximately 2,000 operating hours or annually, depending on operating conditions and compressor application.

6. Is the 39911631 an OEM Ingersoll Rand component?

Yes. The 39911631 is identified as an Ingersoll Rand OEM oil filter element for compatible compressor applications.

7. What are signs of a restricted oil filter?

Possible signs include increased pressure differential, reduced lubrication efficiency, higher operating temperatures, abnormal compressor operation, or reduced performance.

8. Can replacing the oil filter improve compressor reliability?

Yes. Maintaining clean lubricant circulation helps reduce contamination-related wear and supports dependable operation.

9. What other parts are commonly replaced during maintenance?

Typical maintenance items include air filters, air/oil separator elements, lubricants, intake pre-filters, and motor lubrication components.

10. Why use genuine Ingersoll Rand maintenance parts?

OEM components are designed for correct fit, filtration performance, and compatibility with Ingersoll Rand compressor systems.
