PMA12 PTA12
PRESSURE SWITCHES FOR AIR COMPRESSORS
Not just water. This family of pressurestats is the ideal solution for managing a compressor. Equipped with automatic exhaust valve, they are able to evacuate the air from the compressor cylinder for a large number of stop cycles, ensuring the correct restart to the following cycle.
