Product Overview

The Ingersoll Rand 47623613001 / 23708423 Air-Oil Separator is a high-performance separator element designed specifically for Ingersoll Rand oil-injected rotary screw air compressors. Its primary function is to efficiently separate lubricating oil from compressed air, ensuring a continuous supply of clean compressed air while recovering lubricant for recirculation within the compressor lubrication system.

During the compression process, oil is injected into the airend to lubricate moving components, remove heat, and seal the compression chamber. The resulting compressed air contains fine oil droplets that must be removed before the air enters downstream equipment. The 23708423 Air-Oil Separator utilizes a multi-layer coalescing filtration element that captures microscopic oil particles and combines them into larger droplets, allowing the recovered lubricant to return to the compressor oil reservoir while delivering high-quality compressed air with extremely low oil carryover.

Constructed with heavy-duty steel components, high-efficiency fiberglass filtration media, and corrosion-resistant internal structures, the separator is designed to operate reliably under continuous high-pressure and high-temperature industrial conditions. Its optimized flow path minimizes pressure loss, helping improve compressor efficiency while reducing energy consumption and extending maintenance intervals.

Featuring an outer diameter of 240 mm and a weight of 4.9 kg, the Ingersoll Rand 47623613001 / 23708423 Air-Oil Separator provides dependable performance for demanding industrial compressed air systems.

Technical Specifications

Function and Working Principle

The Ingersoll Rand 47623613001 / 23708423 Air-Oil Separator performs the critical task of separating lubricant from compressed air before the air leaves the compressor package.

Compressed air mixed with lubricating oil enters the separator vessel, where centrifugal action removes larger oil droplets. The remaining fine oil mist passes through the multi-layer coalescing filter media, which captures microscopic oil particles and combines them into larger droplets. These droplets drain back into the compressor oil system by gravity, allowing clean compressed air to exit the separator with minimal residual oil content.

The optimized internal design minimizes differential pressure across the separator element, ensuring efficient airflow while maintaining high oil separation efficiency. This contributes to improved compressor performance, lower energy consumption, and reduced lubricant losses.

Key operating features include:

• High-efficiency oil separation
• Low residual oil carryover
• Multi-layer coalescing filtration media
• Low pressure differential
• Heavy-duty industrial construction
• Excellent corrosion resistance
• Improved compressor efficiency
• Extended separator service life
