System Operation
How System Works
• The Aeris tire inflation system is designed to continuously supply filtered, regulated compressed
air to each tire on the trailer. There is no operation required of the driver for the system to function
normally. The only requirement of the driver is to verify the indicator lamp is functioning and to
monitor the system periodically.
• The Aeris system is preset to maintain a specific tire pressure in each tire. The pressure in the
trailer’s air tank must be maintained above the targeted pressure to allow the controller to
continuously supply and maintain the preset tire pressure to all tires.
! IMPORTANT: For Aeris controller to operate properly the air tank pressure must be greater
than the tire pressure target. The controller cannot supply tire pressure above the air tank
pressure.
• When the system is operating properly, the air tank will supply pressurized air to the Aeris
controller. The controller will supply regulated compressed air to the air lines going to each tire. If
a tire is low, air from the trailer air tank will inflate the tire until the targeted tire pressure is
achieved. Regulated air flowing from the controller to the air lines and tires may cause the
indicator light to remain on until the target pressure is reached. Constant pressure remains and is
maintained in air lines and tires at the targeted pressure.
