Air-Zone® 5 Year Warranty Statement.

• Air-Zone® warrants that Air-Zone® ozone generators will be free from defects in material and workmanship for a 5 year Period. The warranty period begins on the date of purchase. The original invoice is required as proof of purchase.

• If an ozone generator is found to be faulty, Air-Zone® will either repair or replace the faulty ozone generator at no charge provided that it is returned to our head office in Virginia USA, or to one of our international dealers.

• Shipping to and from Air-Zone® / Mold-Kill is the customers responsibility.

• To obtain warranty on your Air-Zone® ozone generator the customer must contact us at Air-Zone® / Mold-Kill prior to shipping the unit to obtain an RMA (return material authorization number).

• Damage caused by misuse, neglect or lack of regular maintenance. 

• Ozone elements are limited to 6 months warranty. Their normal life span is expected to be between 3-5 years each.

• Damage caused by a customers improper packaging or shipping procedures if a unit is sent back to us for repairs.

• Extra charges incurred as a result of improper packaging or shipping procedures or extra shipping costs billed to Air-Zone®. 

Be sure to avoid those ozone generators that are "easily and inexpensively upgraded" 
by the addition of more ozone "plates".

Mold-Kill uses multiple transformers in our different models.  How can a single transformer that is used in a small ozone machine be expected to handle the much higher load in a large ozone generator?

The truth is that they use only ONE transformer and are more likely to blow out than machines like our units with MULTIPLE power transformers. 

Simply adding ozone plates to increase the ozone output puts a dangerous extra load on the power transformers. 

When 2 ozone plates are added to a one plate 1000 mg/hr ozone generator, the total ozone output is 2600 mg/hr.  If the transformer was properly sized the ozone output would equal 3000 mg/hr, but the fact that the resulting output is only 2600 mg/hr is absolute evidence that the transformer is improperly sized, especially to upgrade the ozone output.

Since the 3000 mg.hr ozone output was not achieved, it can only be concluded that the missing 400 mg/hr of ozone was lost because the transformer was not able to handle the extra load of the extra ozone plates!

The extra load on the transformer, by the addition of the extra ozone plates, could cause it to overheat and blow out.

Note that some 1000 mg/hr ozone generators try to add up to four extra ozone "plates" but that the total ozone output ONLY reaches the 3600 mg/hr level and not the 5000 mg/hr it SHOULD be.

Trying to double or triple the power of an ozone generator by simply adding more ozone plates is a cheap, unsafe, and not reliable way of trying to increase the ozone output.

Mold-Kill ONLY increases ozone outputs by adding extra ozone elements, AND by properly adding extra power transformers. That's why our models with higher ozone output have even ozone out put numbers like 2000, 4000, or 6000 mg.hr instead of an erratically designed unit that outputs 2600, or 3400 mg/hr.

That's why ozone generators that are "upgradable" by simply adding more ozone plates are not very well designed. The load on the transformer HAS to be radically different on a single or five plate ozone generator. 

This is proven by the fact that when a competitor adds 4 more ozone plates to a 1000 mg/hr machine it does NOT equal 5000 mg/hr. 

The "upgraded" generator now only puts out 3600 mg/hr, the missing 1400 mg/hr of ozone output has been lost because the transformer cannot handle the extra load.

That proves that the load presented to the transformer is radically different when you simply add more ozone plates.  If the transformer has been strained so that it looses that much electrical power, then it can be logically concluded it is that much closer to straining and blowing out. 

Our XT-2000 uses a single transformer. The XT-4000 uses 2 transformers. The XT-6000 uses 3 power transformers.  Our larger models use even more transformers.

We do this because to present a balanced load, and to have even power distribution. 
It is better to use multiple transformers when doubling or tripling the ozone power.
It only makes good sense. It makes for a more balanced ozone machine.

Keep in mind the fact that competitors also use ozone plate technology where each "plate" has 3 pieces in it that can easily move around.  They use a spring system to keep each part of the plate in perfect alignment. A 10 plate, 10,000 mg/hr ozone machine will have 30 separate pieces in its 10 ozone plates!  A 10,000 mg/hr "plate type" ozone machine has 30 parts that must ALWAYS be in perfect alignment or disaster will occur.

If a single piece of the glass or mica non-conductor breaks, cracks, or just slips out of alignment due to a lack of spring tension, then the electrical conductor, screen parts of the ozone elements can arc and cause an electrical short. 
When an ozone plate short outs, the transformer is also shorted out.  No matter how well it is built, a transformer cannot stand being shorted out for very long.  Electrical transformers cannot stand to have a high voltage, zero ohm load on them for very long without being put under a huge amount of strain.

Mold-Kill not only uses multiple transformers in our higher powered units to help balance the load, we also use U.S. patented ozone elements which do not have components in them that can move, or shift out of alignment.  There is no way for them to short out as standard ozone plates can.
