What Makes a Molecular Pump Factory Different from Standard Manufacturing?
A molecular pump factory needs special CNC machining capabilities, clean room assembly areas, and vacuum testing systems. It has to have this to make high-precision turbomolecular vacuum pumps and molecular drag pumps. These facilities must keep to ISO Class 5-7 clean room standards. This is to stop contamination during assembly of components that rotate at speeds between 20,000-90,000 RPM from happening. The manufacturing process is all about precision machining of rotor assemblies, stator blades, ceramic bearing systems, and magnetic levitation components.
