Vacuum motor pump.
ARRAS MAXEI vacuum pump systems are equipped with a 2 or 3-staged motor-pump , made of 1 oil sealed rotary vane type pump with filter, check valve and air ballast and a 1 or 2 roots .The connection to the transformer is done through a manifold with appropriate diameter fitted with an exhaust electrovalve, a safety valve, and an insulating valve.
