Nitrogen Purity: Is it really all that important?

Surprisingly, the answer is yes. Since the atmosphere we all breathe already contains about 78% nitrogen, it is vital that the nitrogen you put in your customer's tires be as pure as possible. If it is not, your customer will not see all the benefits offered by nitrogen, and may turn into an unhappy customer that wonders why the service didn't do all you had promised.

Generally, a nitrogen purity of at least 96% is acceptable, and 96%-98% is optimal. The level of purity is dictated by two main factors:

• The purity output of the nitrogen inflator equipment you are using.
• The number of purge cycles performed on each tire. A purge cycle consists of deflating the tire, then inflating with nitrogen. For example, two purge cycles means a tire is first deflated, then inflated with nitrogen, then done once again. A purge cycle is necessary simply because one cannot start with a tire with zero air in it. For every purge cycle performed, the purity in the tire increases.

In order to obtain the goal of 96%-98% purity, it is necessary to purge a passenger tire at least twice. A larger SUV or truck tire that takes at least 80psi can get by with just one purge.

The NIflate⁹⁹ can be set to one, two or three purge cycles, and uses cylinders of 99.9% pure nitrogen. Nitrogen output is 99.9% every time you use it, and will never degrade over time as a nitrogen generating machine will.
