DeWalt has just quietly released a massive addition to the ToughSystem 2.0 lineup, but it isn’t another organizer or drawer unit. The new DeWalt DXCMST201 is a 20-gallon portable air tank that integrates directly with your storage stack. If you run pneumatic tools and need a serious volume boost without sacrificing mobility, this might be the upgrade your workshop has been waiting for.
What Is It? The DXCMST201 is a 20-gallon auxiliary air tank designed to expand the capacity of your existing air compressor. Unlike a standard compressor, this unit does not have a motor or pump; instead, it acts as a massive reservoir to store compressed air. It connects to your compressor to provide longer runtimes for high-demand tools like framing nailers, grinders, or sprayers.
Key Features & Specs:
Capacity: 20 Gallons (Significant expansion for job site air).
System Compatibility: Features a ToughSystem 2.0 top plate, allowing you to stack toolboxes, organizers, or radios directly on top.
Connectivity: Equipped with 4 Quick Couplers, allowing multiple users to pull from the tank simultaneously.
Mobility: Uses 10-inch pneumatic wheels and a retractable handle, effectively doubling as a dolly for your tool stack.
Manifold: Integrated dashboard with tank and tool gauges plus a high-flow regulator.
Why You Might Need It: If you are working remotely where power is scarce, you can fill this 20-gallon tank near a power source and wheel it to the work area for silent, cordless pneumatic power. It effectively turns your ToughSystem stack into a mobile air station.
Important Note: DXCMST201 vs. DXCM201 If you search for this new item, Google may try to redirect you to the similarly named DXCM201. Do not confuse them.
DXCM201 is a standard 20-gallon air compressor (it has a motor and pump).
DXCMST201 (This item) is an air tank only (no motor). It is designed to work with a compressor, not replace it.
Our Take: This is a smart, albeit niche, release from DeWalt. For finish carpenters or trim crews, this is a game-changer. You can leave the noisy compressor outside or in the trailer, run a single hose to this tank inside the house, and have a silent, massive buffer of air right next to where you are working. Plus, the fact that it serves as a base for your other ToughSystem boxes makes it a highly efficient use of floor space in a van or truck.
The DeWalt DXCMST201 is currently appearing at select retailers like Amazon. It’s a specialized tool, but for the right pro, it solves the “noise vs. power” problem perfectly.
