Features

● Compact size and light weight, it can directly connected to air supply port

  or vacuum port.

● The square design is more suitable for panel mounting, and a variety of

   mounting brackets and panels are available.

● Used for condition monitoring of the vacuum system, optimizing the duty

   cycle and adjusting the system loop.
