How close should an after cooler or refrigerant dryer be to the air compressor?

The recommendation for placing an after cooler or refrigerant dryer about 25 feet or more from the air compressor is based on optimizing the efficiency of the system and ensuring effective operation. When the after cooler or dryer is positioned at an appropriate distance, it can adequately cool the compressed air and remove moisture without the risk of overheating or condensation within the lines.

By placing it too close to the compressor, you may expose the after cooler or refrigerant dryer to excessive heat generated by the compressor itself; this could reduce the effectiveness of moisture removal and cooling. Conversely, if it is positioned too far away, it could lead to increased pressure drops and loss of efficiency. Establishing a distance of about 25 feet strikes a balance, allowing proper function while minimizing heat impact and maintaining optimal airflow within the system. This ensures that the compressed air delivered downstream is cool and dry, which is necessary for various applications that require clean and stable air supply.
