The VIGIA NM143 Tire Guardian System is designed to work with ALL solid-axle vehicles. Invented in 1975, it has been used on Commercial Trucks, Garbage Haulers & Dump Trucks, Buses, Delivery Vans & Trucks, RVs, and Passenger & Cargo Vans for three decades in more than 25 countries around the world.   The VIGIA NM143 system employs a Control Panel, which sits inside the vehicle, in plain view of the driver. High-pressure air lines run from the air supply tank to the Control Panel and out to the individual tires through the use of pipes and hoses mounted carefully under the vehicle. The NM143 Contol Panel has lights and gauges that display the calibrated pressure for all the tires on each axle. So, if the owner wants a different pressure for the tires on the Steer axle than on the Drive axle, it is easily accomplished. The different calibrated pressures will be shown on the panel. If a leak develops, the yellow lights on the Control Panel will begin to flash, alerting the driver that a problem exists. In addition, the driver can view the movement of the gauges to determine the axle location and the severity of the leak. If a catastrophic loss of air occurs, all of the gauges will drop to ZERO and the Red LED will illuminate. This means that the system has shut itself down for safety purposes. No tire other than the damaged one is affected. The vehicle's brakes and suspension will operate normally. This is a built-in safety mechanism for the driver. The VIGIA Tire Guardian System is the World's leading Auto Inflation System, saving money on tire expenses, tire casings and road service calls. VIGIA saves lives by preventing tire blowouts and it keeps drivers safe from unsafe situations on the side of the highway. Finally, VIGIA helps save our environment and natural resources by extending the life of tires, which are made from oil.
