Low Maintenance

The O₂Zone® is resistant to iron- or bio-fouling and requires very little maintenance.  Typical maintenance includes a monthly system check and manual cleaning of the sight glasses and paddlewheel flow meter.  The spiral cone nozzle can operate for years without needing cleaning, and the venturi will become blocked only if large debris enters the water supply.  The oxygen generators require annual replacement of their intake filters and the built in oil-less compressors need to be rebuilt after two or three years at a cost of a few hundred dollars.
