  • How do the mechanical tire inflation systems know when to stop inflating the tire?

    Our control box is designed to only add air to a tire when the tire pressure falls below the set system pressure. Air will stop flowing when the tire reaches the set pressure specified by the customer.

  • Will the tire pressure management system drain the air from the air brake supply?

    No. We use a pressure protection valve to protect the air tank supply

  • How will I know if the system is activated and air is flowing to maintain the pre-set regulated system tire pressure?

    Should tire(s) experience low pressure due to environmental operating conditions or if a tire develops a leak due to a road hazard incident, a warning light mounted on the trailer and visible to the driver will illuminate. The light will turn off once the system pressure is back to the pre-set level. If the light remains on, the driver should be prepared to stop at the next opportunity to inspect the tires.

  • Can I still manually check my tire pressure? And how can I check the overall system pressure?

    To manually check a tire’s pressure, all you need to do is remove the valve stem hose from the tire and use a reliable tire pressure gauge. The overall system pressure can be checked with the gauge either at a rotary union fitting or at the control box valve stem.
