Required Gas check-valve brass NBR

Its required to put the one-way gas check valve at around 30 cm from the gas inlet of the ultrafine bubble mixer. For the submersible ultrafine bubble mixers, the one-way gas check valve can be placed just outside the submersible unit if that's more convenient. The one-way gas check valve avoids water getting into the gas hose and protects the oxygen generator. Please make sure the one-way gas valve is installed correctly with the arrow pointing towards the ultrafine bubble generator as the gas must flow into that direction.

Acniti has also an ozone resistant check valve available from SUS316L with viton seal
