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.
