• Aeris
TM
by STEMCO, an advanced automatic tire inflation system based on patented rotary sealing
technology and precision electronic airflow detection. The system is designed to keep commercial
trailer tires properly inflated using air pressure from the trailer’s braking system.
• The rotary seal employed in Aeris
TM
by STEMCO differs dramatically from currently available systems
and is targeted to increase the reliability and durability of these components substantially. The rotary
seal in an automatic tire inflation system is a critical component – it prevents the higher pressures
needed to inflate commercial tires (typically 100 psi) from leaking into the wheel end, which can
handle no more than 6 psi. Excess pressure can cause the wheel end seal to fail prematurely,
causing lubricants to exit the hub and leaving moving parts susceptible to wear and seizure – a
dangerous scenario. In addition to the high reliability and durability of the patented sealing system,
Aeris
TM
by STEMCO also includes several one-way pressure relief valves per axle to ensure that the
wheel-end is never pressurized.
• Aeris
TM
by STEMCO also includes a very sensitive electronic flow detection technology capable of
informing the driver whether the system is making a minor adjustment to tire pressure or if a major
leak is present. A “Smart Sense” wheel end identification option will inform the driver which wheel
end is taking air – saving time and labor in the search and repair of tire leaks.
• Aeris
TM
by STEMCO represents a leap forward in automatic tire inflation technology. STEMCO starts
with an unwavering commitment to increase the safety of our roadways by protecting the wheel end
from damaging air pressure, and then added several additional safeguards and features. Aeris
augments our BatRF tire pressure monitoring systems to complete our suite of tire pressure
management solutions.
