Air Tank Kit

Q: What should I consider when buying an air tank?

Check five specs: Capacity (0.5–4 gallons covers most automotive uses) Pressure rating (150 PSI standard, 200 PSI for high-output compressors) Port size and count (1/4" NPT, minimum 4 ports) Material (steel for durability, aluminum for weight savings) Included hardware (drain valve, mounting brackets, port plugs) Verify the tank's working pressure exceeds your compressor's shutoff pressure by at least 10%.

Q: What are the benefits of using an aluminum air tank for air suspension?

Aluminum air tanks weigh roughly 30–40% less than steel and resist corrosion without an internal coating, which suits show vehicles and coastal climates. EVIL ENERGY air tanks use reinforced alloy steel rated to 150–200 PSI instead, handling higher operating pressures at a lower cost while relying on an external anti-corrosion coating for rust protection.

Q: What can a 4 gallon air compressor do?

A 4-gallon air tank stores compressed air to provide a steady reserve for air horns, train horns, air suspension, pneumatic tools, tire inflation, and other onboard air systems. Its compact size makes it suitable for trucks, SUVs, RVs, and custom builds where installation space is limited. The tank helps reduce compressor cycling and delivers short bursts of high airflow, but its runtime depends on the compressor output, working pressure, and air consumption of the connected equipment.

Q: Can I install an air tank myself, and what tools would I need?

Yes. Installing an air tank requires a drill with metal bits, an open-end wrench set, Teflon tape for NPT threads, and a level for mounting . Plan 1–2 hours for a tank-only installation or 2–4 hours if wiring a 12V compressor with relay and pressure switch. Mount the tank away from exhaust heat and drain condensation monthly to prevent internal rust.

When your air suspension sags under load, your compressor cycles constantly, or your train horn can't sustain a full blast, the problem is insufficient air storage. This collection covers air tank kits from 0.5 to 4 gallons, rated at 150 or 200 PSI, with multiple NPT ports for compressors, valves, gauges, and air lines.

Each tank uses reinforced alloy steel with an anti-corrosion coating and precision-welded seams. Whether you need a compact 1-gallon air suspension tank for a daily driver or a 4-gallon reserve for a custom compressed air system, these kits include the drain valve, mounting hardware, and port plugs. The compressor combo kit adds a 12V pump, pressure switch, and relay harness for a complete onboard air solution.

What are the main differences between 11-gallon and other portable air tanks?

An 11-gallon portable tank stores roughly 3× the air volume of a 4-gallon fixed tank, making it better for filling multiple large tires or running pneumatic tools away from a power source. It weighs 25–35 lbs empty and requires manual transport. Fixed onboard tanks (0.5–4 gallons) refill automatically via a 12V compressor and stay permanently mounted under the vehicle.

Can I install an air tank myself, and what tools would I need?

Yes. Installing an air tank requires a drill with metal bits, an open-end wrench set, Teflon tape for NPT threads, and a level for mounting. Plan 1–2 hours for a tank-only installation or 2–4 hours if wiring a 12V compressor with relay and pressure switch.
