Aeris
®
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 air system.
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 thus leaving
moving parts susceptible to wear and seizure – a dangerous scenario. The rotary seal employed in Aeris
® by STEMCO
differs dramatically from currently available systems and is targeted to increase the reliability and durability of these
components substantially. In addition to the high reliability and durability of the patented sealing system, Aeris
® by
STEMCO also includes several one-way pressure relief valves per axle to ensure that the wheel-end is never
pressurized.
Aeris ® by STEMCO also includes a high resolution 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. An additional
safety feature is a pressure protection valve to protect the integrity of the air brake system in the case of a major and
continuous air leak such as a blow out or other catastrophic tire failure.
Aeris ® 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.
