    Nitrogen tyre inflation Romax


    We have a PSA (Pressure Swing Absorption) Nitrogen InflationTyre Machine.


    Based on the latest PSA technology, the machine uses a Carbon Molecular Sieve (CMS) to separate nitrogen from the other gases contained in the air. Compressed air contains mainly nitrogen and oxygen and when it enters the CMS, nitrogen molecules are able to pass through but oxygen is absorbed.


    The compressed air in a tyre comprises 20.9% oxygen plus water vapour. The air expands when hot and contracts when cold giving variations in tyre pressure. When it is hot, the oxygen permeates through the tyre wall causing pressure loss. Moisture in the air is not good for the tyre or the wheel.


    Nitrogen provides constant pressure and is less susceptible to diffusion through the tyre caused by changing temperatures. Nitrogen inflation minimises moisture content and so takes away the corrosive element.
