## Overview

The SP-5G Ozone Generator delivers up to 5 grams per hour of ozone with adjustable output, using advanced air-cooled corona discharge technology to reduce chemical use by up to 95%. Engineered for professional-grade pool sanitation, it minimizes chlorine irritation and odor while maintaining crystal-clear water. Requires external air or oxygen supply and venturi injector for optimal operation.

## Description

Please note: use a venturi injector to create vacuum effect during ozone application. Use degasifier and ozone destructor to ensure proper dissipation of ozone.

Review: This unit has been churning out O3 for about two ... - This unit has been churning out O3 for about two months now, 24/7, and is still going strong operating in humid NE air. (Keeping the air dry at the unit's intake air flow rate is a work in progress at this writing.) It has an important feature applicable to avoiding pool pump drain-down when the pool circulation is off -- there is an inlet line fitting that may be connected to a refrigeration valve to shut off the air feed to the unit. This avoids having the valve in the unit's O3 output line to the injection venturi where even a stainless-steel valve may be degraded (lubricant or elastomer wise) by the O3. This unit puts out enough O3 that any use of brass fittings in the O3 path will lead to brass failure within a few days.
Review: Commercial quality cornoa discharge generator - Well constructed and wired inside. Replace a older cornoa discharge unit I had that was manufactured by hand in what looked to by a hobby box. The old one would corrode all of its internal wiring each season, and had questionable effectiveness when it got hot outside. I was already convinced on the idea that the UV ozone generators, like most of the Delzone units, produced very little ozone, and seemed way overpriced/gimmick. While I appreciate that this unit is fan cooled, and likely much more effective than the old one I had, it designed to be installed indoors, or at least in a weatherproof cabinet. Originally I was going to install it in my basement, opposite of the wall where my equipment resides, but that would have put it bellow-water level and risked it getting damaged by backflow. The fan is also louder than I cared for. I ended up purchasing a cabinet from L-COM, NB181608-03V, which was a 18x16x8 vented, weatherpoof NEMA 3r enclosure and just mouting the A2Z ozone generator in it outside. I use some extra insulator foam board I had (house wrap) and some thick self adhesive weather stripping to separate the top/bottom of the cabinet so the fan in the ozone generator would draw air though one vent and out the other. The cabinet was another $200 though, so that upped my investment in this more than I would have liked. I would be much happier if the cabinet was weatherproof by design, as it doesn't seem like there is any reason why the whole thing couldn't have been manufactured in a L-COM style cabinet. I've had a few near-90 degree days, high humidity, and the cabinet isn't getting very hot inside, but I don't have a thermometer installed. This unit did not come with a venturi injector or mixing chamber, but I already had that stuff built into my plumbing. I also ended up buying a silica dryer from a2z to pre-dry the input air. I would have purchased it during my original plan anyway had I expected to install it outdoors (very humid summers here) I've had it installed for about a month now, and its definitely evened out the pool chemistry, clarity and brought my chlorine use down to a minimum. I keep the water around 86, run the pump 12hr/day over 3 separate schedules, @25,000 gallons. Manufacture would call for the 8g, but its covered with a tarp-style automatic cover when not in use (no sunlight or debre) - so demand is reduced. Add 1/1.5 gallons of bleach every 7-10 days (the big 3 packs of Clorox, unscented works well), and chlorine levels will stay in the .5-2 PPM range weekly. (Bleach is no different than a reduced-concentration liquid shock from the pool store) Regardless, not having to worry about my unattended pool either turning green or reaching crazy cholorine levels (due to the cover decreasing demand so much), I'd buy it all again. Even after the extra parts, its still cheaper than the delzone units the pool store would sell me that produce a trivial amount ozone.

*by J***S on July 2, 2018*

I bought this to replace an Eclypse unit that had run its course. Easy install as most o the hardware, Venturi etc, was already there. Works great.
