OZONE GENERATOR REVIEW
If you've been searching for ozone generators online, no doubt you've discovered some things. First, no other ozone vendor wants to show you the inside of their ozone generator nor reveal the power (in kilovolts) of their ozone generators power source or the specs in general. You'll also find ozone generator vendors, with a few exceptions, want to reveal the replacement cost for their ozone plates (if even offered). Some even claim to have "permanent" ozone elements. Before you buy an ozone generator, it's best to learn a few simple truths to help you make an informed decision:
1) Ambient air contains 21% oxygen. A high voltage ceramic ozone element such as the one we use fed at least 100 cubic feet a minute and powered by at least a 3KV (3000 volts) power source (ours are 4KV) can produce up to 3600 mg/h of ozone per hour. Fed 2000 CFM of air from say a box fan will not however increase the ozone production! Only feeding the plates pure oxygen can increase ozone production.
2) Attaching 2-4 ceramic ozone plates to one 4KV power transformer will not double the amount of ozone. It will still only produce up to 4000 mg/h if you use a 4KV power source. The plates will turn a dark purple in the dark when powered by 1 transformer. Two plates powered by 1 transformer will glow half as bright as the electricity is being divided, and also the ozone production.
3) In order to produce 14,000 mg/h of ozone, you would need to utilize at least a 14,000KV transformer (cost over $500, not likely) Higher power transformers are not as stable as lower power transformers either. For this reason, we've found that using multiple 4KV transformers in our higher output units is better than using 1 high powered transformer that could feed several plates.
4) MICA plates with their stainless steel mesh are only capable of producing around 400 mg/h of ozone per plate when fed ambient air. Viewed by the naked eye in the dark, they will barely turn purple (very little electrical spark going on to split 02 into 03). The vendors who claim to produce 18,000 to 24,000 mg/h use these types of ozone plates which by the way are falsely said to be " permanent" as in "will last forever". There's no such thing as a permanent ozone plate.
5) All other ozone generators on the market feature "prone to fail" parts that ozone destroy's over time. Thus, you'll find most lower priced ozone generators only come with a 1 year warranty. If the units do fail during the warranty period, you'll be paying $30-$70 for shipping your unit back and forth. If it fails after the warranty period, we're told some vendors charge $100's to repair your ozone machine. Ozone Generator USA's "ForeverOzone" (tm) brand of ozone generators are the only ozone machines made to last a lifetime! We back the most expensive part, the power generator with a lifetime warranty. The only two other parts that can fail, (besides the fuse) are the 110 CFM fan and the high voltage ozone element (both rated for over 10,000 hours). We sell both of these parts in our shopping cart for $15-$20. The fan is covered by a 1 yr warranty from the manufacturer by the way, in case it does fail prematurely. (less than 10,000 hours).
Before you buy an ozone generator folks, make sure you get the specs in writing. Don't listen to the sales pitch, listen to the specs! For instance, the MaxBlaster utilizes a 4KV transformer and draws about 1 amp of electricity, therefore, it will produce around 4000 mg/h of ozone if the wire mesh plates are functioning properly. The makers of the Bio3Blaster with their "ozone cannon" don't provide any information besides the dimensions of their unit, however, upon close scrutiny, I discovered their 1.5 HP "cannon" is somewhat of a dud and produces only 105 CFM while sucking up 700 watts of electricity! Don't believe me, see the picture below and click on it to view the Max Air Spa Blower's specs (that's what they use in their "cannon") then click here to view a picture of this spa blower next to the rubber tool box they use as a cabinet
.
Granted, the blower's 105 CFM rating is probably the amount of air it can push through water, and without water, it may be able to push 2 or 3 times more air, we don't know, it doesn't qualify the CFM rating, however, something using 7 AMPS is bound to get very hot very quickly and blow HOT air, not good for ozone production, not to mention not good for the rubber tool box they use to house their "cannon". They love to point out the design flaws in AirZone and MaxBlaster units, hope they don't mind we point out the design flaws in their unit. I know we wouldn't mind if someone gave us constructive criticism on our units; we're always looking to make improvements, lol. The reason why computers, servers, and electronic devices use cooling fans is because those fans don't draw much amps and don't run hot and they do what they're supposed to do, cool things down and create around 100 CFM of air movement per fan. We use 2 such fans in our 2 generator model OG-7200 because we determined one fan wasn't providing enough cooling and air movement for the 2 generators for instance. Our 10 generator model, the Turbo Ozone Blaster uses a 2000 CFM box fan to cool the transformers and supply the 10 plates with all the oxygen and disperse the ozone as far from the unit as humanly possible. A 20" box fan only cost around $15 and doesn't use that much electricity. Sure, it's a "Simple" approach, but Simple is our middle name! Perhaps the Bio3Blaster makers might consider adding a cooling fan to cool down their 7AMP behemoth spa blower to keep it from getting too hot in their rubber tool box. Not sure those air vents will be enough if someone were to leave that unit unsupervised in an attic for 24 straight hours, not to mention the exorbitant amount of electricity that it would waste.
I hope this ozone generator review has answered some of your questions about ozone generators. I hope you ask pointed questions before you buy an ozone generator. The simple fact is ozone generators are pretty basic electronic components and don't justify the $500-$2000 prices some vendors demand. Heck, you can buy a used car for that, and last time I checked an ozone generator doesn't have a transmission or engine! Now you know why most vendors won't show you the inside of their ozone machines! If they did, you'd say the same thing that nice old lady used to say in that famous "Wendy's" commercial; "Where's the Beef!" Now you know the truth. Hopefully it will free you from wasting your money.
