The rotating parts are not in contact with the casing during rotation. There is therefore no friction during operation and thus no internal lubrication is necessary. The gas moving through the machine remains uncontaminated and completely oil-free.

The other main advantages of using the MAPRO® MCF centrifugal fans are:

• easy installation;
• low noise level;
• no vibration;
• pulsation free gas flow and no surge;
  minimal maintenance.
