Vehicle Inspection Systems' VIS-Nitro automates nitrogen tire inflation and saves time. The VIS-Nitro is a high performance nitrogen generator and automated tire inflation system for vehicles and fleets. By providing an automated inflation cycle, operators can simultaneously inflate up to four tires to the optimum pressure while performing other tasks. The tires are inflated with dry nitrogen, which lengthens tire and wheel life, improves fleet fuel economy and enhances safety through consistent and proper tire pressure.
