The oil cooler (Part No. 1622318900) is a key thermal management component in Atlas Copco GA30 and GA45 screw compressors. These mid-power compressors operate with high oil circulation rates and continuous load, making stable oil temperature control critical for airend efficiency and bearing protection.
This model is engineered as a platform-matched aluminum heat exchanger, ensuring precise fitment, correct oil flow balance, and optimal heat transfer performance within the GA30 / GA45 cooling architecture.
Designed for GA30 & GA45 Operating Profiles
GA30 and GA45 compressors run at higher thermal loads compared with smaller units. The oil absorbs significant heat from rotor compression, internal friction, and discharge air. If this heat is not removed quickly and consistently, oil viscosity drops, oxidation increases, and bearing wear accelerates.
The 1622318900 oil cooler is built to match the oil flow volume and pressure characteristics of these models, allowing the lubrication system to remain stable even during full-load and high-ambient-temperature operation.

High-Efficiency Aluminum Core
This oil cooler uses a precision-formed aluminum core with optimized internal passages. Aluminum provides excellent thermal conductivity, enabling rapid heat transfer from the oil to the cooling air stream.
The internal channel geometry increases surface contact between the oil and the cooler walls, improving heat dissipation without creating excessive flow resistance. This ensures that oil pressure and lubrication delivery to the airend remain consistent.
Contribution to Compressor Reliability
By maintaining oil temperature within the correct operating range, the 1622318900 oil cooler protects critical components such as:
- Airend rotors and housing
- Main and thrust bearings
- Shaft seals and O-rings
- Oil separator efficiency
Stable oil temperature reduces sludge formation, extends lubricant service life, and improves overall compressor efficiency, especially in GA30 and GA45 units running long duty cycles.
Installation & Maintenance
To achieve full cooling performance, airflow across the oil cooler must be kept clean and unobstructed. Dust, oil mist, or debris buildup on the fins can significantly reduce heat dissipation.
During routine maintenance, the cooler should be inspected for contamination, oil residue, and airflow restriction to ensure consistent thermal performance.
Why a Model-Specific Oil Cooler Matters
Unlike generic heat exchangers, the 1622318900 oil cooler is engineered to match the thermal load, oil flow rate, and cooling airflow of the GA30 and GA45 compressor platforms. This ensures not only better cooling efficiency, but also longer airend life, more stable operating pressure, and reduced unplanned downtime.
For operators and service teams maintaining Atlas Copco mid-range screw compressors, this aluminum oil cooler is a critical component in keeping the system running safely and efficiently.
