Boosters are compressors that suck in the already compressed air and compress it further.


Compressed air dryer

Air contains a high amount of water vapour at high temperatures and less at lower temperatures. If air is compressed, the water vapour concentration further increases. Compressed air dryers reduce the water vapour in the compressed air.

The compressed air thaw point indicates the water content of the compressed air. It indicates the temperature at which water vapour starts to condense. A lower compressed air thaw point always indicates a lower water content of the compressed air.
