How Do I Choose an Air Tank?

When building an air suspension setup, a few factors come into play when choosing the right air tank.First and foremost, consider how much space you have for mounting the tank. Next, how much air capacity do you need? That can be tricky to determine if you’ve never used air suspension before, but a good rule of thumb is that a 15-liter tank is a solid standard for a passenger car. Smaller 9.5-liter tanks need to be refilled more often, and if your vehicle requires a lot of air to raise, the compressor may need to run continuously during lift to keep up. 

Those who use larger tanks - such as the 19-liter tank from Air Lift - often choose to run dual compressors, which is recommended for that volume. This significantly shortens the refill time, which is convenient since no one wants to hear the compressor running all the time. 

How to Drain an Air Tank

When purchasing a complete kit, a drain kit is usually included. However, if you’re building your own system, it’s a good idea to buy a drain valve to install at the bottom of the tank. Because of changing weather conditions, condensation tends to build up and collect at the bottom of the tank. It’s good practice to empty the tank periodically by opening the drain valve.Most of the time, there may be little to no water inside, but the less moisture that circulates in your system, the better.
