Vacuum supports are available to withstand a full system vacuum, eliminating damage to the rupture disc and ensuring proper operation. For backpressure conditions higher than 14.7 psig (1,01 barg), consult your local representative or the factory. When ordering a Standard or Composite rupture disc that will be subjected to a vacuum condition, clearly specify the exact conditions that the rupture disc will encounter. Vacuum supports are manufactured to be an integral part of the rupture disc and are permanently attached to ensure proper installation.
