| Piston compressors are mainly of the air-cooled variety. Cold air has the advantage that it is almost everywhere in unlimited quantities.
The cold air is generated by a ventilator. The ventilator forces the cold air over the intercooler and aftercooler and over the compressor.
During compression and cooling stage of the compressed air, condensate forms inside the cooler. Because of the flow speed of the compressed air, the condensate is taken out of the aftercooler by the air, and into the pipe network and compressed air tank. |
