VIAIR (20007) Air Source Tank
The VIAIR 20007 is a robust, weather-proof air source tank designed for off-roaders and mobile air systems. With a 200 PSI working pressure, it supports air horns and on-board air applications. Best for buyers who need durable, high-pressure performance in challenging outdoor conditions. A limitation is that its features emphasize mounting and durability over high-port versatility, so users planning complex plumbing should verify compatibility with their system.
airmaxxx 5 Gallon Steel Air Tank
The airmaxxx 5 Gallon Tank offers a larger storage capacity with seven ports, including multiple 1/2″, 3/8″, and 1/4″ NPT options. Rated up to 200 PSI, it suits air suspension, air horns, or onboard accessories. Best for users needing flexible plumbing and higher port count. A potential drawback is its heavier weight and bulk compared to smaller tanks, which may affect installation in compact vehicles.
EVIL ENERGY 2.5 Gallon Tank Kit
The EVIL ENERGY 2.5 Gallon Tank Kit provides a compact, easy-to-install option with six 1/4″ NPT ports and a 200 PSI rating. It includes essential installation accessories, making it a strong choice for smaller projects like air horns, tires, or light suspension work. Choose this for tight spaces where a full-size tank would be impractical. Limitation: smaller capacity means more frequent recharges for sustained use.
AUX20S Portable 20 Gallon Steel Tank
The AUX20S from California Air Tools combines 20 gallons of storage with light weight—about 42 pounds. It features 1/4″ female and male quick connectors for straightforward plumbing. Best for portable users who need a large tank without heavy lifting on every setup. Limitation: portability may come with compromises in mounting flexibility on some vehicles.
Vixen Air 5 Gallon Tank
The Vixen Air 5 Gallon Tank features nine ports and a steel construction with powder coating for corrosion resistance and a clean look. It suits suspensions, air ride, and train horn setups with ample port options. Best for users who require multiple connections and a sturdy, visually durable tank. Limitation: the larger port count can complicate initial plumbing for simple systems.
Buying Guide
- Capacity and duty cycle: 20 gallons is a balance between storage and space. Larger tanks reduce recharge frequency but require more mounting space.
- Port configuration: More ports provide flexibility for multiple accessories. Plan your layout before purchasing to ensure compatibility with hoses and fittings you own.
- Pressure rating: A 200 PSI rating is common for heavy-duty air systems. Confirm your compressor and accessories can safely operate at this pressure.
- Material and durability: Steel and reinforced aluminum tanks resist corrosion and offer long-term durability in harsh environments. Consider your mounting location and exposure to elements.
- Installation kit: Some tanks include drain valves, hoses, tape, and mounting hardware. A complete kit reduces additional shopping and installation time.
- Port size and alignment: Ensure port sizes align with your planned accessories (horns, suspension components, inflators). Mismatched ports can lead to leaks or flow restrictions.
- Port accessibility: Larger diameter ports reduce bottlenecks in high-demand applications. This is important for air-riding systems and train horns.
Frequently Asked Questions
