Product Overview

The Ingersoll Rand 47588694001 / 39911631 Oil Filter is a high-performance replacement oil filter designed for industrial air compressor lubrication systems. It plays a critical role in protecting the compressor by removing contaminants from circulating lubricating oil before the oil reaches precision mechanical components.

Clean compressor oil is essential for maintaining efficient lubrication, minimizing component wear, reducing operating temperatures, and extending equipment service life. The oil filter continuously captures particles generated during compressor operation, preventing contaminants from circulating through bearings, gears, rotors, and other critical internal assemblies.

With dimensions of 290 × 50 × 119 mm and a weight of 2.27 kg, this oil filter is designed for use in compatible Ingersoll Rand industrial air compressors operating under demanding conditions.

Technical Specifications

Function and Working Principle

The oil filter continuously cleans the compressor lubricant while the machine is operating.

Typical oil circulation process:

Oil Tank → Oil Pump → Oil Filter → Compressor Lubrication Circuit → Return to Oil Tank

During operation, the filter removes:

• Metal particles
• Carbon deposits
• Dust contamination
• Oxidized oil residue
• Mechanical wear particles
• Other solid contaminants

Only filtered oil continues through the lubrication system, ensuring reliable protection of critical compressor components.

Importance in Compressor Lubrication

The oil filter is one of the most important maintenance components in an industrial air compressor.

Its primary functions include:

• Removing contaminants from lubricating oil
• Protecting bearings and rotating assemblies
• Reducing internal wear
• Maintaining oil cleanliness
• Extending compressor service life
• Improving operational reliability

Without proper oil filtration, contaminants can circulate throughout the lubrication system, accelerating wear and increasing maintenance costs.
