Product Overview

The Ingersoll Rand 47560118001 22219174 Air-Oil Separator is a replacement separator element designed for use in compatible industrial compressed-air systems. Its primary function is to separate lubricating oil mist from compressed air in rotary screw compressors, allowing the recovered oil to return to the compressor’s lubrication circuit while cleaner compressed air continues toward the outlet.

In an oil-injected rotary screw compressor, lubricating oil performs several important functions. It helps seal internal clearances, lubricates moving components, and removes heat generated during compression. During operation, some of this oil becomes entrained in the compressed air as a fine mist. The air-oil separator removes much of this entrained oil before the compressed air leaves the compressor package.

The 22219174 separator element uses a coalescing filtration process. Fine oil droplets collect within the filter media, combine into larger droplets, and drain toward the oil collection area. This process helps reduce oil carryover into downstream compressed-air equipment and supports the recovery of compressor lubricant.

The part number 22219174 is associated with certain Ingersoll Rand compressor packages, including RM185i, M200–M250, MM250, and V200/V250 model families. However, compressor compatibility should always be checked against the equipment model, serial number, separator tank arrangement, and applicable parts documentation.

For maintenance teams, selecting the correct separator is important for maintaining compressed-air quality, controlling oil consumption, and preserving the operating condition of the compressor.

Function and Working Principle

The air-oil separator is an essential component in an oil-injected rotary screw compressor. Its purpose is to reduce the amount of lubricating oil carried out with compressed air while allowing the recovered oil to return to the compressor.

1. Oil Mist Separation

During compression, lubricating oil mixes with the incoming air inside the compressor element. The oil helps provide sealing, lubrication, and cooling. As the air-oil mixture leaves the compression stage, it enters the separation system.

The separator element provides a filtration structure through which the compressed air passes. Fine oil droplets are captured by the coalescing media instead of continuing with the air stream.

2. Coalescing Filtration

Coalescing filtration works by collecting small liquid droplets and combining them into larger droplets.

As the air passes through the separator media, microscopic oil droplets contact the fibers and accumulate. The droplets gradually merge, forming larger quantities of liquid oil that can drain from the filter structure.

This process reduces oil carryover and helps maintain the quality of compressed air supplied to downstream equipment.

3. Oil Recovery

The separated oil collects within the designated area of the separator assembly. Through the compressor’s oil-return arrangement, recovered lubricant is directed back toward the oil sump or lubrication circuit.

Returning oil to the compressor reduces unnecessary lubricant loss and supports the continuous operation of the oil-injected compression system.

A restricted or damaged oil-return line can interfere with this process. Therefore, maintenance should include checking the relevant return components as well as the separator element.

4. Compressed-Air Discharge

After passing through the separator, the compressed air continues toward the compressor outlet and downstream treatment equipment.

The separator is not a complete substitute for downstream compressed-air filtration or drying. Applications requiring specific air-quality classes may also need suitable aftercoolers, moisture separators, dryers, and line filters.

5. Pressure-Drop Management

The separator creates resistance as air passes through its filtration media. Under normal operating conditions, this resistance remains within the equipment’s acceptable range.

As the filter becomes contaminated or reaches the end of its service life, pressure drop may increase. Excessive restriction can affect compressor efficiency and operating conditions.

Monitoring separator differential pressure is therefore an important part of preventive maintenance.

Role in Industrial Compressed-Air Systems

The 47560118001 22219174 separator element supports the oil-management process in compatible Ingersoll Rand rotary screw compressors.

Oil Circuit Protection

The separator helps recover lubricant from the compressed-air stream. Maintaining effective separation can reduce unnecessary oil loss and help preserve the compressor’s lubrication supply.

Correct oil recovery is important because insufficient lubricant can affect internal sealing, cooling, and component lubrication.

Compressed-Air Quality

Oil carryover can affect downstream air equipment, pneumatic valves, instruments, and production processes.

An effective separator helps reduce the amount of oil entering the compressed-air distribution system. Where more demanding air-quality requirements apply, additional treatment equipment should be installed according to the process specification.

Compressor Operating Efficiency

A separator in good condition allows compressed air to pass through its media with an acceptable pressure drop. A heavily restricted element may increase the energy required to maintain the required discharge conditions.

Replacing the separator according to the compressor manufacturer’s maintenance recommendations helps maintain appropriate operating performance.

Equipment Reliability

Oil contamination downstream of the compressor can create maintenance problems for pneumatic equipment and production machinery. Maintaining the separator helps reduce this risk and supports stable operation of the compressed-air system.

Industrial Applications

The Ingersoll Rand 22219174 separator element is intended for compatible oil-injected compressor installations. Its application should be determined by matching the part number to the compressor’s approved parts documentation.

1. Industrial Manufacturing Facilities

Manufacturing plants use compressed air for pneumatic actuators, production machinery, material handling, and general plant services.

An effective air-oil separator helps reduce lubricant carryover from the compressor into the plant’s compressed-air network. This supports cleaner air delivery to downstream equipment.

2. Automotive Production

Automotive production facilities use compressed air for pneumatic tools, assembly equipment, material handling, and various production operations.

Oil carryover can affect air-operated components and downstream filtration equipment. Maintaining the separator helps control this source of contamination.

3. Metalworking and Machinery

Metalworking facilities use compressed air for pneumatic controls, machine tools, cleaning operations, and automated equipment.

The separator helps maintain the performance of the compressor’s oil-management system and reduces the amount of lubricant carried into the compressed-air line.

4. Packaging and Processing Equipment

Packaging machinery may use compressed air for product positioning, pneumatic cylinders, actuators, and automated handling systems.

A properly maintained separator helps reduce oil contamination in the compressed-air supply. Additional air treatment may still be required where the process has strict cleanliness requirements.

5. General Industrial Utility Systems

Large industrial facilities often operate centralized compressor rooms to supply multiple production areas.

In these systems, separator maintenance is important because compressor performance affects the reliability of the entire compressed-air network.

Installation and System Integration

The air-oil separator must be installed correctly to maintain the compressor’s internal oil circulation and compressed-air performance.

1. Confirm the Compressor Model

Before purchasing the 22219174 separator, identify the compressor model, serial number, and separator tank configuration.

The part number is associated with selected Ingersoll Rand compressor families, but not every machine within a broad product series necessarily uses the same separator assembly.

Compare the existing element and parts documentation before installation.

2. Shut Down and Depressurize the Compressor

Before maintenance, shut down the compressor and isolate its electrical supply. Follow the manufacturer’s lockout and tagout procedures.

Allow the system to cool and verify that the separator tank and connected components have been safely depressurized.

Never open a pressurized separator vessel. Trapped compressed air and hot lubricant can cause serious injury.

3. Remove the Existing Separator

Open the separator assembly according to the compressor maintenance instructions. Carefully remove the existing element and inspect the surrounding housing.

Check for contamination, damaged sealing surfaces, accumulated oil deposits, and other conditions that may affect the new element’s installation.

4. Inspect Sealing Components

Inspect the sealing surfaces and associated gaskets or O-rings. Replace damaged or unsuitable sealing components according to the manufacturer’s recommendations.

A damaged seal can allow unfiltered air or excessive oil carryover, reducing the effectiveness of the separator system.

5. Install the Replacement Element

Confirm the replacement part number and physical configuration before fitting the new element.

Install the separator in the correct orientation and follow the manufacturer’s tightening and sealing instructions. Avoid applying excessive force that could damage the housing or sealing surfaces.

6. Check the Oil-Return System

Inspect the oil-return line, pickup tube, and associated fittings where applicable.

A blocked or damaged return line can prevent recovered oil from returning to the lubrication circuit. This may cause increased oil carryover even when the separator element itself is new.

7. Restart and Inspect

After reassembly, verify that all connections and covers are correctly installed. Restore the electrical supply and restart the compressor according to the approved procedure.

Check for oil leakage, abnormal pressure conditions, unusual noise, and other signs of improper operation. Record the maintenance date and separator part number for future service planning.

Alternative Models and Replacement Considerations

The 22219174 separator has cross-reference listings under several replacement and filtration brands. However, cross-reference numbers should be treated as identification aids rather than automatic approval for every compressor installation.

Before selecting an alternative, compare:

• Overall height and diameter.
• Internal and external diameter references.
• Filter-media construction.
• Airflow capacity and operating conditions.
• Permissible pressure drop.
• Collapse-pressure requirements.
• Seal dimensions and material.
• Oil-return arrangement.
• Compressor model and serial number.

A separator with similar dimensions may not provide the same filtration performance or mechanical compatibility. Always use the approved part number or a documented equivalent.
