For sealing compressors, gas-lubricated mechanical seals have proven to be the most economical solution. They operate on the basis of the contact-free relative movement of the rotor and stator at extremely high speeds and with a minimum gap size. Microstructures introduced into the running surface provide the “air cushion” that allows contact-free rotation. The crucial advantages are no maintenance and minimum leakage: For this application, 3M™ offers 3M™ Silicon Carbide and 3M™ Silicon Nitride Gas Seal Rings for use in gas-lubricated mechanical seals.
