ACTIVAIR is a Central Tire Inflation System (CTIS) engineered specifically for off-road enthusiasts who demand performance, convenience, and total control. By automatically inflating or deflating all four tires on the fly—without ever leaving your seat—ACTIVAIR allows drivers to adapt instantly to changing terrain, altitude, or temperature. Whether you're airing down for a better grip on rocks or airing up before highway merging, ACTIVAIR ensures you always have the optimal tire footprint for maximum traction, safety, and performance. No more compromises, no more delays—just seamless transitions between terrains so you can spend more time enjoying the trail.

ACTIVAIR CTIS’s expertise is proven by 30 years of military experience and success in U.S. off-road racing.

WHAT YOU GET WITH OUR ACTIVAIR SYSTEM

1. The Control Panel

Mounted inside your vehicle, the ACTIVAIR touchscreen is your control center. With just a tap, choose your targeted pressure or manually adjust tire pressure without ever stepping outside.  

Each situation has its own requirements. ACTIVAIR offers different ways to manage tire pressure according to your specific needs — all through the same interface, allowing full control in either Automatic or Manual mode.  

• Automatic mode: Use the 4 terrain buttons to automatically adjust all tires to your personalized pressure. Perfect for driving on the trail! 
• Manual mode: Use the “+” and “-“ buttons to make precise adjustments to one or more tires. Perfect for leveling your rig before camping!

2. The Electro-Pneumatic Control Unit (EPCU)

This intelligent module connects your onboard air compressor to all corners of the vehicle. It receives commands from the control panel and precisely drives air to each tire. The EPCU ensures reliable, fast inflation and deflation while driving or stationary, using high-performance valves and pressure monitoring.  

3. The Valves

Bolted directly on each CTIS-compatible rim, the valves allow air to flow into the tire or out of it. Our valves have the specificity of being closed if the CTIS is not used. This feature offers you several advantages: 

• Reliability: If the hose is torn off, the air does not escape from the wheel.  

• Easy maintenance: the wheel can be dismantled as if there was no CTIS. There are no extra tubes to disconnect.  

  Designed for durability and off-road use, they work seamlessly with the EPCU to maintain your target pressure—even in extreme conditions.
