- Ozone gas backflow prevention
- Isolation of ozone from an oxygen concentrator
- Prevention of water damage to an ozone generator
- Direct use on Mazzei Venturi (see below)
We use this venturi directly on the Mazzei venturi. The standard check valve supplied with a Mazzei venturi is made out of Kynar material and does not always create a leak-proof connection and may leak water slowly past the seal in many situations. By removing the stock check valve and threading this check valve directly on the Mazzei venturi, a more secure connection is possible with stainless fittings, and a positive check valve with a positive seal is used.
