Nitrogen is used to fill tires and the science behind it is simple. Nitrogen molecules are bigger than air molecules, so they leak out of tires more slowly, meaning they stay inflated at the correct pressure longer.
How it works
Atmospheric air contains essentially 78% nitrogen and 21% oxygen. Compressed air is passed through a technically advanced bundle of hollow membrane fibers. Nitrogen gas is separated from the feed air by selective permeation. Water vapor and oxygen rapidly permeate safely to the atmosphere wihile the nitrogen gas is discharged under pessure into the user's nitrogen piping system, where it is ready to be used.
Features & Benefits
Superior membranes constructed from high quality aluminum with technically advanced fiber for outstanding performance from 90-99.5% nitrogen purity.
True Purity Controller ensures that nitrogen purity from our unit remains constant under all flow conditions with a single screw adjustment
Comes complete with 4-stage filtration to ensure long membrane life
Engineered for simplicity, durability and ease of use make the PMNG what we believe to be the most user friendly unit in the market. All pre-filters and controls are included inside the canopy. Only a supply of dry compressed air is needed to get nitrogen at the outlet of the generator. Also the start-up procedure of the PMNG is made so straightforward that it does not require any specialist.
