ONAIR KNOWLEDGE / AIR SUPPLY
ONE COMPRESSOR OR TWO?
A good air supply is about reserve, recovery and how you actually use the system. More hardware isn't automatically the right answer for every car.
Your air tank stores compressed air. The compressor refills it after adjustments. Choosing the right combination means balancing available space, electrical capacity, tank size, operating pressure and how often you raise or lower the suspension.
COMPACT AND PRACTICAL
SINGLE COMPRESSOR
A strong choice for a simpler installation when the tank reserve and compressor's rated recovery suit your daily adjustments.
- Less mounting space and hardware
- Simpler plumbing and electrical installation
- Lower initial component cost
- Recovery rate depends on the selected model
ADDED RECOVERY CAPACITY
DUAL COMPRESSORS
Worth considering when adjustments are frequent or you need additional tank recovery capacity and have the room and wiring for it.
- Potentially faster recovery with matched compressors
- Additional mounting and power requirements
- Each compressor needs suitable protection
- Correct air plumbing and service access still matter
THE DETAIL PEOPLE MISS
YOUR TANK CHANGES THE EXPERIENCE.
A larger air tank gives you a greater volume of stored air at a given pressure, but it also takes more air to refill. Pair a larger tank with a compressor setup that matches how often you plan to adjust the car. The best combination isn't necessarily the one with the biggest components.
Use the compressor manufacturer's current duty-cycle, pressure and current-draw specifications, and make sure the tank and other pneumatic components are appropriately rated for the system's operating range.
THINK ABOUT THESE FIRST.
How often will I adjust ride height?
Occasional parking adjustments and frequent height changes place different demands on your air reserve and tank recovery. Think about actual use, not just a show-day scenario.
Where will the compressor and tank live?
Measure usable trunk, frunk or concealed space, including mounting clearances, ventilation, secure attachment, drainage and future service access.
What changes when I add a second compressor?
Electrical planning becomes especially important. Verify wire runs, relays, fusing, grounding and vehicle electrical capacity for both devices rather than assuming a single-compressor circuit will be enough.
BUILD THE AIR SUPPLY AROUND YOUR CAR.
Review the actual compressor ratings, tank options and available management packages before ordering.
