Frequently asked questions

What components make up an air management system? ⌄

An air management system typically includes a compressor, air tank, valves or a valve block, pressure sensors or switches, airlines, a control unit or switches, and in full air setups, height sensors. Together they control how air is delivered to the airbags or struts and how the system maintains or adjusts ride height.

Do I need a tank for automatic ride levelling? ⌄

Yes. Any automatic ride-levelling or preset height system requires an air tank so there is enough stored air to raise the vehicle quickly without overworking the compressor. The tank buffers demand and allows smoother, more reliable height changes.

What is the difference between manual and electronic air management? ⌄

Manual systems use simple paddle valves or switches to control air pressure by feel, and are typically used for Load Assist or basic custom setups. Electronic systems use solenoid valves, height sensors and an ECU to manage presets and maintain ride height automatically. Legal full-air conversions generally require some form of automatic height control.

Why must some adjustments be disabled while driving? ⌄

Regulations typically require that major ride-height changes do not occur while the vehicle is in motion. Electronic air management systems usually monitor handbrake or vehicle speed and only allow height changes when stationary or below a defined speed, to maintain safety and stability.

What is the maximum air pressure for the Boss Air Master Plus Onboard Air system? ⌄

The Boss Air Master Plus system operates with a maximum pressure of 150 psi, which is suitable for most air tools and tyre inflation needs.

Can I use the Boss Air Master Plus to inflate large 4x4 tyres? ⌄

Yes, the Boss Air Master Plus is designed to provide a good volume of air supply, making it suitable for inflating large 4x4 tyres efficiently.

Is the Boss Air Master Plus compatible with my existing Boss Load Assist kit? ⌄

Absolutely. The Boss Air Master Plus is designed to control your Boss Load Assist kit from inside your cab, providing seamless integration for your air suspension needs.

What type of compressor is included in the Boss Air Master Plus kit? ⌄

The kit includes the Boss PX-07, a 3/4 hp 12-volt compressor, which is robust enough for continuous use and suitable for both airbag inflation and powering air tools.

How does the air tank in the Boss Air Master Plus compare to other options? ⌄

The Boss Air Master Plus features a 3-gallon (9 litre) aluminium air tank, which is lightweight and resistant to rust, ensuring longevity and reliability compared to steel tanks.

What is the purpose of the mini regulator included in the kit? ⌄

The mini regulator with gauge is used to supply regulated air to your air lockers, ensuring that the seals are protected and that the lockers operate effectively under varying conditions.
