Never Run Out of Breath: The DEWALT 20 Gallon Portable Surge Tank

Anyone who relies on pneumatic tools knows the frustration of outrunning their air compressor. You are in the middle of a major framing job, your nail gun starts firing blanks, and you have to stop and wait for the compressor to catch up. Or worse, you have a crew trying to share one small tank, and productivity grinds to a halt.

If you are tired of waiting on air, it’s time to add a serious buffer to your setup. Meet the DEWALT 20 Gallon Portable Surge Tank. This isn’t a compressor itself; it is a massive air reserve that hooks up to your existing system, drastically extending your runtimes and allowing multiple people to work simultaneously without missing a beat. Best of all, it seamlessly integrates with your existing DEWALT gear.

1. Massive Air Reserve: A large 20-gallon capacity means significantly longer air tool runtimes and less cycling for your primary compressor, saving wear and tear on your expensive equipment.
2. Multi-User Capable: Equipped with 4 Quick Couplers, allowing an entire crew to plug in and work from the same air source without constantly swapping hoses.
3. Smart Dashboard: The integrated dashboard features a high-flow regulator alongside both tank and tool gauges, giving you precise control and instant visibility of your air pressure.
4. TOUGHSYSTEM 2.0 Compatible: The ultimate job site hack. It connects seamlessly with your DEWALT TOUGHSYSTEM® 2.0 toolboxes and accessories, letting you stack your gear and roll your entire pneumatic setup in one trip.
5. Built for the Job Site: Features a rugged retractable handle and heavy-duty 10-inch pneumatic wheels that effortlessly roll over rough terrain, debris, and cords.
6. Safe and Secure Transport: Includes two sturdy handles for easy loading and unloading into the truck, plus 4 tie-down holes to keep it locked down tight during transit.

For the Trades & Professionals

1. Framing and Roofing Crews: Hook this surge tank up to your main compressor, and multiple carpenters can run high-demand framing or roofing nailers simultaneously without experiencing pressure drops.
2. Mobile Mechanics & Auto Shops: Ideal for running impact wrenches, air ratchets, and die grinders. The extra 20 gallons of air means you can bust loose stubborn bolts without waiting for the compressor motor to kick back on.
3. Commercial Painters: Gives spray gun operators a much larger, consistent volume of air, reducing the chance of pressure spikes or drops that can ruin a delicate finish.

For the “Regular Person” (DIYers & Homeowners)

1. Garage Workshops: If you have a smaller pancake compressor, hooking it up to this surge tank essentially gives you the capacity of a massive shop compressor without needing a 220V outlet to power a larger motor.
2. Winterizing Sprinkler Systems: Blowing out irrigation lines requires a large volume of sustained air. This surge tank stores exactly what you need to clear the pipes before the first winter freeze.
3. Restoration Projects: Perfect for running high-drain tools like air sanders or media blasters in the driveway, where continuous airflow is an absolute must.

Is this an air compressor?

No. The DEWALT Surge Tank does not generate its own air; it is an auxiliary storage tank. You connect it to your existing air compressor via a standard air hose, and it holds a 20-gallon reserve to keep your tools running longer.

Does it come with the TOUGHSYSTEM toolboxes?

No, the toolboxes and accessories are sold separately. However, the tank is designed with built-in compatibility, meaning your TOUGHSYSTEM 2.0 boxes click and lock right onto the top of the tank for incredibly easy transport.

Why do I need a surge tank if I already have a compressor?

Small, portable compressors are great for mobility, but their small tanks run out of air quickly with high-demand tools. A surge tank gives you the best of both worlds: the massive air volume of a stationary shop compressor paired with the portability of a job site tool.

Can I leave it pressurized during transport?

While the tank is built incredibly tough, it is always a best practice to drain your air tanks after use to prevent moisture buildup inside the steel tank and to ensure completely safe transport in the back of your truck or van.

To get the absolute most out of your massive new air reserve, you need the right gear to power it, the right tools to use it, and the right system to transport it. Here are three compatible DEWALT products available at Acme Tools that pair perfectly with your Surge Tank:

1. DEWALT 6 Gallon 165 PSI Electric Pancake Air Compressor: Why it pairs well: You need a compressor to fill your surge tank! Hooking up this highly portable, high-output 6-gallon pancake compressor to your 20-gallon surge tank gives you the massive, sustained air capacity of a stationary shop compressor with the easy mobility of a job site setup.
2. DEWALT 15 Degree Coil Framing Nailer: Why it pairs well: Framing nailers are notorious air hogs. With your surge tank providing a 20-gallon buffer, you (and a partner) can fire these industrial-grade coil nailers continuously at high speeds without suffering from pressure drops or un-driven nails.
3. DEWALT TOUGHSYSTEM 2.0 Rolling Tool Box Mobile Storage DS450: Why it pairs well: Because the surge tank is TOUGHSYSTEM 2.0 compatible, you can lock this rugged, all-terrain rolling toolbox directly into your air setup. It allows you to haul your nailers, hoses, and fittings all at once, saving you multiple trips back to the truck.
