    The components of the Model Z-7G are mounted in a rugged stainless steel cabinet, and all parts that come into contact with oxygen and ozone are made of stainless steel, PTFE, quartz glass or ceramic tube.

    The Refurbished Model Z-7G ozone generator uses a fan-cooled Corona Discharge (CD) tube to generate ozone from a variety of pressurized sources such as compressed air, bottled oxygen or an oxygen generator. The Model Z-7G also has a built-in light-duty air compressor to generate its own compressed air. The result is high ozone concentration yields at low energy demand.

    Switches and LED status indicator lights are provided for the ozone generator and the air compressor. The concentration of ozone discharged is controllable from 0 to 100% by a dial potentiometer to vary the current to the CD tube, as displayed on a 300-800mA amp meter.  The unit is protected electrically by an externally-accessible fuse.

    The Model OZ-7G ozone generator comes complete with pre-installed fittings and all required tubing, enabling it to be installed and running in less than ten minutes.
