Why does outlet pressure drop on Concoa INTELLISWITCH?
- K
  Kelsey HayesAug 20, 2025
  If the outlet pressure from your Concoa Switch drops below the adjusted value, it could be due to several reasons. The flow demands on the system may be greater than the cylinders can supply, in which case you should replace or resize the cylinders. Alternatively, the cylinder pressures might be too low, requiring you to change the switchover pressure on the IntelliSwitch. The switchover pressure may also be set too low for the application.

Why Concoa INTELLISWITCH does not switch automatically?
- C
  Crystal WilsonAug 26, 2025
  If your Concoa Switch is not automatically switching from one side to the other, verify that the pressure on the destination side is greater than the switchover pressure setting. If it is not, restore pressure to the proper operating level. Also, check that the switchover pressure setting is correct for the cylinder size and inlet pressures required.

What to do if there is no delivery pressure on Concoa INTELLISWITCH?
- H
  haneywilliamAug 28, 2025
  If you see pressure readings on both inlet displays of your Concoa Switch but there's no delivery pressure, it might be because the air supply is off or its pressure is too low; restore pressure. Another possibility is that the internal regulator for the valve system is plugged or faulty, requiring you to clean or replace the internal regulator.

  If you observe a pressure reading on the left inlet display but no pressure on the right inlet display or outlet display of your Concoa Switch, and your system uses delivery process gas activation, ensure the right side is pressurized for gas delivery. Restore a minimum of 80 PSI pressure to the right side.
