How do I know if I need an ozone compatible air vent?

An ozone compatible air vent is needed if you intend to fill a vessel with ozonated water and keep it under pressure. Air vents ensure that air/ozone can escape from a water tank thereby preventing air from collecting inside. Remember that in certain ozone injection setups, ozone/air can also collect in water pipes. If this occurs ozone gas will be ejected out of nozzles which can cause harm to personnel. An air vent can keep your employees safe!

What is important when considering an air vent?

One of the most important features in an air vent is a large process connection. The process connection on the AVSS-11 is 3/4-in FNPT. This is important because water and air must pass through the process connection at the same time, in different directions.

Is the AVSS-11 serviceable in the event of failure?

No, due to the welded construction, if the AVSS air vent cannot be made operational by using the troubleshooting methods outlined in the manual. Please replace the defective unit when needed.
