Frequently asked questions

Are Boss air tanks made from steel or aluminium?

All Boss air tanks are manufactured from aluminium. This keeps weight down and eliminates internal rust, which is a common issue with steel tanks, especially in humid environments or where moisture is not drained regularly.

Do I still need to drain an aluminium air tank?

Yes. Even though aluminium tanks do not rust internally, moisture from compressed air still collects in the system. Periodic draining removes water and helps protect valves, airbags and other components from corrosion and contamination.

What size tank do I need for my air suspension setup?

The ideal tank size depends on how the system is used. Load Assist kits that only adjust airbag pressures can run on a small tank or even no tank with a suitable compressor. Full air suspension, frequent ride-height changes, tyre inflation or air tools all benefit from a larger tank. Bigger tanks provide more usable air but take longer to fill.

Why can't you give a generic tank fill time?

Tank fill time depends on several factors – compressor output, duty cycle, tank volume, system pressure and ambient conditions. Because these vary widely between setups, there is no single accurate fill time that applies to every combination. It is better to size the compressor and tank based on how often and how quickly you need to use the air.

What are the dimensions of the 3 Gallon 9ltr Aluminium Air Tank?

The dimensions of the 3 Gallon 9ltr Aluminium Air Tank are 460mm long, 210mm high, and 180mm wide. It weighs approximately 3.05 kg.

How many ports does this air tank have and what are their sizes?

This air tank features a total of five ports: two centre end ports with a size of 3/8 NPT and three surrounding end ports with a size of 1/4 NPT.

Is this air tank suitable for heavy-duty applications?

Yes, the 3 Gallon Aluminium Air Tank is constructed from high-quality aluminium, ensuring durability and resistance to rust. It is suitable for both light and heavy-duty applications, depending on the overall air system setup.
