Best Air Compressor Add on Tank Options for More Pressurized Power and Convenience
Choosing a supplemental air tank can boost your shop workflow by delivering steady pressure, extending tool runtimes, and reducing cycling on your main compressor. The following selections are top-rated add-on tanks, each with practical features like built-in gauges, safety valves, and durable construction. Below you’ll find five models that cover a range of capacities and uses—from portable 5-gallon tanks to larger 13-gallon systems—so you can match your needs for nailers, tires, inflatables, and light shop spraying. The included summary table in the introduction highlights key specs at a glance.

| MaxWorks 51010 Portable 5 Gallon Tank | MaxWorks | 5 Gallon | Built-in pressure gauge, safety valve, 40″ hose |
| BIG RED T88007 7 Gallon Tank | BIG RED | 7 Gallon | 125 PSI max, built-in safety features, tire inflation ready |
| Performance Tool W10005 5-Gallon Tank | Performance Tool | 5 Gallon | PSI and MPa gauge, lightweight with tire chuck |
| VEVOR 13-Gallon Air Compressor Tank | VEVOR | 13 Gallon | Quiet operation, high capacity for long tasks |
Metabo HPT Reserve Air Tank Ua3810ab
The Metabo HPT Reserve Air Tank UA3810AB delivers a high-capacity 10-gallon reservoir designed to keep nailers powered as pressure remains steady across long runs. The unit includes an industrial shut-off valve for filling and disconnecting without draining, and five quick-connect couplers enable immediate access for multiple tools. Angled steel legs provide stability on busy shop floors. This tank is ideal for assemblies requiring consistent PSI when the compressor is distant from the work zone.
MaxWorks 51010 Portable 5 Gallon Tank
The MaxWorks 51010 offers a compact 5-gallon solution with a manageable weight and a built-in pressure gauge. Its 40-inch reinforced PVC hose facilitates easy tool connections, and the unit includes a safety valve rated to safeguard operators. A built-in handle supports transport, making it suitable for mobile projects or small garages where space is at a premium.
BIG RED T88007 Portable Horizontal Tank
The BIG RED T88007 is a horizontal 7-gallon tank with a practical footprint, offering a maximum working pressure of 125 PSI and a built-in relief valve for safety. Its layout makes it suitable for emergency tire inflation, blow cleaning, and recreational inflation. The integrated gauge displays pressure in PSI and Bar, supporting straightforward monitoring during use.
Performance Tool W10005 5-Gallon Tank
The Performance Tool W10005 provides a practical 5-gallon capacity with an easy-to-read gauge displaying PSI and MPa. It features an industrial-grade hose and a tire air chuck for quick tire inflation and other standard tasks. A lightweight, comfortable handle enables mobility between job sites or storage locations within a shop environment.
VEVOR 13-Gallon Air Tank
The VEVOR 13-Gallon Air Tank pairs a large-capacity reservoir with a 2HP motor for rapid air buildup and sustained performance. It operates quietly at approximately 66dB thanks to oil-free technology, reducing noise in home workshops. The unit includes wheels for easier movement and is designed for versatile tasks including tire inflation, woodworking, auto repairs, and spray painting.
Buying Guide: Choosing The Right Add-On Tank
- Capacity and duty cycle: Larger tanks like 10–13 gallons improve runtime for multiple tools, but require more space and heavier handling. Smaller tanks are portable and convenient for quick jobs.
- Pressure rating and safety: Look for a tank with a clear pressure gauge, a safe working pressure (PSI), and a built-in relief or bypass valve. Some units include shut-off valves to avoid draining when disconnected.
- Portability vs. stability: Portable tanks typically have handles and compact footprints, while horizontal tanks with stable bases and legs prevent tipping during operation.
- Connectivity: Multiple quick-connect couplers simplify tool switching. Ensure your tank offers compatible fittings for your tools and hoses.
- Noise and maintenance: Oil-free designs reduce maintenance, and quieter models help in shared spaces. Consider wheels or casters for easier relocation.
- Materials and durability: Steel tanks with reinforced hoses and corrosion-resistant fittings provide longevity in shop environments.
The best add-on tank depends on your workflow. For nailer-heavy framing or trim work, a 10-gallon model with several couplers (like the Metabo HPT UA3810AB) can sustain multiple tools without constant cycling. If you need a portable, lightweight option for tire inflation or light repairs, a 5-gallon unit with a gauge and hose is typically sufficient (as with the MaxWorks or Performance Tool models). For larger projects or longer sessions, a 7–13 gallon tank (such as the BIG RED or VEVOR 13-gallon) minimizes interruptions and keeps air pressure steady across longer tasks. Always verify compatibility with your compressor, hoses, and tools to maximize efficiency and safety.
