Filter Oil For Oil Injected Screw Compressors 2903752501

Filter Oil For Oil Injected Screw Compressors

The Atlas Copco 2903752501 Oil Filter is a replacement lubricant filter designed for compatible Atlas Copco oil-injected screw compressors.

During compressor operation, lubricating oil continuously circulates through the compressor system. The oil filter removes contaminants and unwanted particles from the circulating lubricant before the oil returns to critical compressor components. Maintaining clean lubrication helps protect the compressor element and associated components from contamination-related wear.

Atlas Copco identifies 2903752501 as “FILTER OIL FOR OIL INJECTED SCREW COMPRESSORS.” The part is also listed in Atlas Copco service-pack assemblies, including 1500-hour maintenance packages.

 

Designed for Oil-Injected Screw Compressors

Unlike an air filter, the 2903752501 is installed in the compressor’s lubrication circuit rather than the intake-air system.

It is intended for compatible oil-injected rotary screw compressors, where the lubricant performs several functions during compression.

The oil filtration system is particularly important because contaminated lubricant can affect components such as:

• Screw compressor element
• Bearings
• Lubrication passages
• Oil circulation components
• Oil cooling system

Using the correct filter helps maintain the intended oil-flow and filtration characteristics of the compressor lubrication system.

Maintenance Applications

Atlas Copco’s current Parts Online data lists 2903752501 in service-pack assemblies including:

• U1 Service Pak 1500H / 2 Year
• U2 Service Pak 1500H
• U3 Service Pack 1500H

This indicates that the filter forms part of scheduled compressor maintenance programs for applicable equipment.

The actual replacement interval should always follow the maintenance schedule specified for the particular compressor model and operating conditions.

Typical Compressor Applications

Third-party application data associates 2903752501 with a range of Atlas Copco oil-injected screw compressors, including certain GA-series machines. For example, one European filter supplier lists GA 55 VSD, GA 75 VSD and GA 90 VSD applications.

Other industry documentation also identifies 2903752501 as an oil filter for Atlas Copco oil-injected rotary screw compressors, including GA-series applications.

Important: Compatibility should be confirmed against the compressor model and serial number before ordering.

When Should the Oil Filter Be Replaced?

Oil filter replacement is normally performed as part of scheduled compressor servicing rather than waiting for a major performance problem.

Depending on the compressor model and operating environment, maintenance requirements may be affected by:

• Operating hours
• Compressor load
• Ambient temperature
• Dust and contamination levels
• Lubricant condition
• Compressor operating environment
• Manufacturer maintenance schedule

A restricted or contaminated oil filter can affect lubricant circulation and increase stress within the lubrication system.

For this reason, the oil filter should be replaced at the recommended service interval using the correct part reference.
