The air cooler is an accessory used together with cable blowing machines to reduce the temperature and moisture level of compressed air coming from the compressor. During cable blowing operations, compressed air temperature can increase significantly due to the compression process. This heated air may soften the cable jacket and duct wall, increasing friction and reducing installation performance.

By cooling the compressed air before it reaches the blowing machine, the air cooler improves installation efficiency, protects the cable jacket, reduces friction inside the duct, and helps achieve longer blowing distances.

How the Air Cooler Works

The air cooler operates using an air-driven fan system. Compressed air from the compressor powers the air motor, which rotates the fan and allows ambient air to cool the compressed airflow through a heat-exchange process. The unit is installed between the compressor and the cable blowing machine.

Without cooling, compressed air exiting the compressor may reach temperatures approximately 30–35°C above ambient temperature. With an air cooler, this temperature can be reduced to around 10°C above ambient temperature.

Maintaining lower air temperature prevents duct deformation, protects the cable outer jacket, and improves blowing distance and installation speed.
