Why nitrogen in tyres?

The air we breathe consists largely of nitrogen, oxygen and water. Oxygen and water from compressed air have a negative impact on tyres. They negatively influence handling, fuel efficiency, tyre life, the environment and your own safety. The solution is to inflate your tyres with a high concentration of nitrogen.

Advantages of nitrogen in tyres

• Increased fuel efficiency (reduced CO₂ emission)
• Increased tyre life (more stable tyre pressure, less oxidation of the tyre)
• Increased safety (more reliable tyre pressure, lower tyre temperature, improved grip and handling)
• Increased rim life (nitrogen is completely dry; no oxidation of the rim)

All of the aforementioned advantages benefit the environment!

How nitrogen is created with Parker hollow fibre membranes

Parker hollow fibres are small, straw-like plastics. In a module, which is a tube, thousands of these straws are glued in. Only the ends of the bundles of fibres are glued in, in the middle the fibre hangs free.

Because the space between the fibre ends is glued, once you put compressed air on the module, the air has to go inside the fibres. The plastic fibres behave in such a way that their walls “like” the oxygen and water molecules much better than the nitrogen molecules. The fibres let the oxygen and water molecules pass easier through the wall than the nitrogen molecules. The water and oxygen molecules can leave the module, the nitrogen molecules stay inside the fibre and will come out at the other glued end of the fibre.
