Husqvarna Blastrac 2‑20DT Walk‑Behind Shot Blasting Machine: Power Meets Precision

When refurbishing large industrial floors—like parking garages, warehouse slabs, airports, or roadway structures—surface preparation is the foundation for successful coatings, traction, and safety. The Husqvarna Blastrac 2‑20DT delivers that essential prep with unbeatable power, consistency, and dust-free operation. This self‑propelled, walk‑behind shot blaster combines rugged build quality and operator-friendly features, making it a smart investment for contractors who demand performance and precision on medium to large-scale jobs.

Heavy-Duty Design with Real Muscle

Under the hood, the 2‑20DT is powered by dual 28.3 hp blast motors—equivalent to approximately 2 × 15 hp (11 kW) units—that deliver a broad 22‑inch (550 mm) blast width in a compact chassis. The unit operates on 480/277 V, 60 Hz three-phase power, drawing around 45 A, which aligns with standard commercial site infrastructure. Despite its 1,334‑lb weight, integrated lifting eyes and quick-lift rear casters make transporting it through doorways or between job locations surprisingly manageable.

Self-Propelled Efficiency on Any Incline

One of the standout capabilities of the 2‑20DT is its self-propelled drive. Featuring an AC inverted drive motor with an integrated brake, the machine maintains steady speed across inclines—essential for multi-level parking decks or ramped surfaces. Ergonomic handle-mounted drive controls allow operators to maintain a smooth, consistent pace without fatigue—even in forward and reverse operation.

Cleaning and Profiling in One Lap

Rather than relying on multi-step processes, the 2‑20DT cleans, strips, and profiles surfaces simultaneously with its closed-circuit shot blasting system. Twin blast motors project steel shot downward, effectively removing contaminants while creating a roughened finish ready for coatings. This all-in-one process eliminates several labor steps and accelerates project timelines.

Professional tests show the 20‑inch model can cover up to 4,850 ft²/hour (450 m²/h) under optimal conditions, with steel shot consumption hovering around 78 lb/hour (75 g/m²)

Virtually Dust-Free with Closed-Circuit System

Dust control is critical on modern job sites. The 2‑20DT is designed to hook up to Blastrac dust collectors like the DC‑975 or DC‑975 combo systems. Once tied into a closed dust circuit, it operates with minimal airborne particles—improving visibility, air quality, and project compliance. The unit connects via a 6-inch hose and pairs efficiently with cartridges and bag options available in dust collector kits.

Durable Construction = Low Total Cost

Built with a pressed-liner blast housing, the 2‑20DT improves wear life and facilitates simple liner swaps during maintenance. The dual 11 kW motors add redundancy for long runtime capability, and designers engineered the machine for compactness—able to fit through standard doors and maneuver deliver this performance using standard jobsite power.

The result is a machine that offers both low operating cost and predictable maintenance schedules—vital for contractors managing fleet uptime on tight timelines.

Ideal for a Wide Range of Industries

The 2‑20DT is not limited to warehouse concrete. Its aggressive blasting capabilities make it suitable for a broad range of surfaces:

• Parking garages and ramps—removes tire rubber, resin coatings, and restores anti-skid performance.

• Industrial floors—strips coatings, epoxy, and adhesives with ease.

• Airport and highway rehab—preps runways and road surfaces for overlays.

• Ship decks and bridge surfaces—cleans steel and concrete for recoating or corrosion prevention

Operators praise the machine’s versatility, calling it “resource-smart” for its reuse of abrasive media and minimal environmental impact.

Performance That Meets Compliance

For contractors working under strict regulations—whether environmental, safety, or industry standards—the 2‑20DT checks all the boxes. Its closed-circuit dust control, UL-certified electrical systems, emergency-stop controls, and conformity with European safety directives (CE-marked) ensure safer operation on industrial and commercial sites .

Noise levels hover around 83 dB(A), and vibration is kept under 2.5 m/s²—meaning operators aren’t subjected to excessive hearing hazards or whole-body vibration.
