Standard Pneumatic Rotary Unions

A pneumatic slip ring is a mechanism used to transfer fluid (under pressure or vacuum) from a stationary inlet to a rotating outlet, preserving and isolating the fluid connection.

  • Number of Circuits :2/4/6/8/10/12
  • Current: 2A each circuit or higher
  • Insulation Resistance: ≥500VAC@50Hz
  • Wire Length: 250mm(optional)
  • Voltage: 240VAC/DC
Standard Pneumatic Rotary Unions

The LPP rotary unions can perform rotation of 360 degrees. The medium includes inert gas such as compressed air, steam, vacuum, nitrogen, hydrogen, etc. It can integrate slip ring to transport various control signals. The sealing surface and sealing ring are made of special materials, with the advantages of wear resistance, long life, corrosion resistance, and no leakage. Customers can install LPP rotary unions independently according to the application environment.
