Air Tanks for Truck Air Systems for Sale

Reserve Capacity. Ensure System Stability.

When you’re outfitting a heavy-duty truck, specialty service vehicle or vocational rig with an air-brake, suspension or pneumatic-tool system, the air tank (reservoir) often acts as the unsung hero of uptime and reliability. A properly sized, durable air tank helps your compressor cycle less, maintains steady pressure during peak load, protects components from moisture/vibration damage, and keeps your system working when it matters most. According to major parts suppliers, heavy-duty truck air tanks are built to standards such as SAE J10 and tested to twice the nominal working pressure.

What We Offer

At Custom Truck One Source, our air-tank accessory category delivers both new and used units tailored for vocational trucks, service bodies, crane trucks, rail-service trucks and other heavy-duty rigs. You’ll find:

• Steel or aluminum reservoirs sized for truck/chassis-class use, often with multiple port options and corrosion-resistant coatings.

• Single- and multi-compartment tanks designed for air-brake systems, pneumatic service tools, or suspension/air-ride integration.

• Mounting kits, brackets, drain ports, sensors and hardware to support installation and retrofit.

• Specification support to help you choose the correct tank size (volume and diameter), port configuration, mounting layout and corrosion protection for your environment.

Key Features & Considerations

When selecting an air tank for your truck or upfit, focus on these critical criteria:

• Volume & dimensions: The tank must hold enough air for your system demands (brakes, tools, suspension) while fitting your mounting location.

• Material & durability: Look for steel or aluminum tanks built to heavy-duty specs, often internally and externally coated to resist corrosion and meet testing standards.

• Port configuration & mount style: Ensure the tank has the correct number, size and location of ports (drain, supply, tool ports), and that mounting brackets match your chassis or body layout.

• Certification & standards: Tanks built to standards such as SAE J10 or FMVSS 121 ensure they’ve been tested for pressure, corrosion and longevity.

• Application & environment fit: Consider whether you’ll be in cold or high-humidity climates, exposure to road salt, off-road terrain, or mobile-service conditions — these affect material choice and mounting strategy.

Typical Uses & Industries

Air tanks are relevant across a broad spectrum of truck and fleet applications:

• Vocational truck fleets (dump trucks, service trucks, utility trucks) where air systems power brakes, tools or auxiliary systems.

• Custom upfits (rail-service trucks, crane trucks, maintenance rigs) where pneumatic tools, air-ride, or dump-body systems require stable air reserves.

• Mobile service trucks and mechanics’ rigs where onboard compressed air must support tools, inflation, suspension and more.

• Fleet maintenance or refurbishment programs replacing old or corroded tanks to extend vehicle life and reduce downtime.
