Air Compressor Air Oil Separator Filters

Replacement Air Compressor Air Oil Separator Filters

ProAirSupply supplies replacement air/oil separator filters for industrial compressed air systems and rotary screw air compressors. Air/oil separators are an essential part of the compressor system, helping separate lubricant from the compressed air before it leaves the compressor.

Proper separator performance helps maintain compressor efficiency, reduce oil carryover, protect downstream equipment, and return separated lubricant to the compressor oil system for reuse.

How Air Oil Separator Filters Work

In many rotary screw compressors, oil is injected into the compression chamber for lubrication, sealing, and cooling. This creates a mixture of compressed air and oil that must be separated before the air is delivered downstream.

The air/oil separator removes suspended oil from the compressed air stream. The separated oil is then returned to the compressor oil sump or lubrication circuit, while the cleaned compressed air continues through the system.

Benefits of Replacing an Air Oil Separator

• Reduced oil carryover: Helps minimize lubricant entering downstream compressed air piping and equipment.
• Improved compressor efficiency: A properly functioning separator supports normal airflow and pressure performance.
• Protection of downstream equipment: Helps reduce oil contamination in pneumatic tools, valves, controls, and other compressed air components.
• Oil recovery: Separated lubricant can be returned to the compressor for continued use.
• Reduced maintenance: Proper separator maintenance can help prevent excessive oil consumption and contamination-related service problems.

Air Oil Separator Filter Applications

Air/oil separator elements are commonly used in oil-injected rotary screw compressors and other compressed air equipment where lubricant must be removed from the compressed air stream before discharge.

Replacement separators are available for many compressor manufacturers, compressor models, and OEM part numbers.

Finding the Correct Air Oil Separator

The most reliable way to identify the correct replacement separator is by using the OEM part number, compressor manufacturer, and compressor model.

Separator elements that appear similar may have different diameters, heights, flange configurations, gasket arrangements, or internal construction, so verify the complete part number before ordering.
