System Features
• Tire pressure is continuously monitored and adjusted automatically to the target tire pressure.
• Adjustable air pressure regulator is used for setting desired tire pressure target.
• An indicator light will illuminate when air is flowing to the tires.
• Does not pressurize axle tube (prevent contamination of seals).
• Rotary seal air leakage will not enter the wheel end, preventing oil contamination on the hubcap.
• Each wheel end has dual venting paths to prevent wheel end pressurization.
• Checks tire pressure constantly.
• Integrated check valves in the hoses isolate tires from system if a tire is damaged or leaking.
• Tire pressure check ports are integrated into each hose, eliminating the need to remove the hose to
check the tire pressure.
• An air filter is provided on the inlet air line to prevent particulates from clogging the system.
Aeris Specifications
• Tire pressure setting range: 70-120 psi
• Pressure check interval: Continuously supplies air to tires
• System power requirements at 12VDC: < 12W.
• Minimum power voltage requirement to operate: 9 VDC
• Indicator light current range: 50 mA to 600 mA
• Tire inflation capacity (per tire): 10 psi in 2-3 minutes
• The indicator light provides the following system information:
• No light: System is good or does not power
• Power up: Light blinks three times
• No pressure: Long flash followed by 2 blinks repeating.
• Low volume flow: Constantly on
• High volume flow: Blinking constantly
