TyreSaver 3.0 has been developed and produced by Parker Filtration and Separation in Etten-Leur, The Netherlands. The result is a robust, lightweight, mobile, nitrogen tyre inflator for the automotive industry, with low investment costs and strong profit margin. As it is based on filtration process, the workshop tool can be connected to a compressor and automatically generates nitrogen from compressed air: a simple concept that is, above all, inexpensive. The TyreSaver 3.0 is fitted with an exchangeable membrane cartridge that will operate for thousands of tyre inflations. The patent is currently pending.
Parker Hannifin recommends nitrogen in order to avoid air leaking through the tyre wall or bead, which results in under-inflation. The reason why nitrogen is used is because it is easy to produce, inhibits combustion, has no smell and is also a component of the air we breathe. The theory is that the difference between the pressure in a tyre and the pressure outside causes oxygen to permeate through the tyre and, explains the company, “If we can create the same concentration of oxygen inside and outside a tyre (equal partial pressure), then oxygen is not forced to leak through the tyre wall.” (Tyres & Accessories/Staffordshire, U.K.)
