OZ-4AD : 4 gram/hour Ozone Generator


Product Overview

This ozone generator uses dry air, from the integrated air dryer, to produce 4 g/hr of ozone. 

The OZ-4AD is a vacuum driven ozone generator that requires vacuum from an ozone injector, or compressor, to pull ozone through the system, and to the point of use. When used with an ozone injector to inject ozone into water, this is a very simple system. 

The integrated vacuum switch will start and stop ozone generation based on air flow. The visual flow meter will indicate when air is flowing through the ozone generator. The moisture indicator will indicate the quality of the dry air flowing through the OZ-4AD.
