The Husqvarna Blastrac 1-8DPS30 Shot Blaster (SKU 970691801) is a compact, self‑propelled walk‑behind blasting machine engineered for small to medium‑sized concrete, asphalt, and steel surface preparation projects. With an 8‑inch working width, 4 hp motor, and closed‑circuit abrasive system, it strips, cleans, and profiles surfaces in a single pass, delivering a consistent profile ready for coatings, overlays, or sealers.

What Is the Husqvarna Blastrac 1-8DPS30 Shot Blaster?

The Husqvarna Blastrac 1-8DPS30 is an 8" walk‑behind steel shot blasting machine designed for preparing horizontal surfaces before applying new coatings or toppings. It propels steel shot onto the surface, then recovers and recycles the abrasive in a closed system, removing contaminants while etching a controlled surface profile.

This model is optimal for small to medium jobs such as industrial floors, warehouses, garages, and commercial spaces, and it also works as a complementary unit for edges and tight areas when larger shot blasters are used on open sections. Because it is self‑propelled with fingertip drive controls on the steering handle, the operator can maintain a consistent pace and pattern with less fatigue than with push‑only machines.

Key Features and Design Benefits

The 1-8DPS30 combines productivity, ease of use, and durability in a compact package. Standout features include:

• Self‑propelled drive with controls on the steering handle, allowing simple speed and direction control at your fingertips.

• 8" (200 mm) working width, ideal for small to mid‑size areas, edges, and lanes.

• Closed‑circuit blasting system that recycles steel shot and contains dust when paired with a suitable dust collector.

• EZ‑adjust control cage system for fine‑tuning blast pattern and profile without complex tools.

• Laser‑cut components, powder‑coated frame, and robust construction for a long service life.

• Vacuum hose containment bracket and 3" dust hose connection for better hose management and cleaner operation.

• Slide‑out shot screen tray with integrated EZ‑grip handle for quick abrasive inspection and removal of debris.

These features make the 1-8DPS30 a reliable workhorse for contractors who need repeatable surface profiles on a variety of substrates.

These specifications give the 1-8DPS30 enough power and weight to generate a strong blast pattern while still fitting through standard doors and working in confined spaces.

How the 1-8DPS30 Shot Blaster Works

The Blastrac 1-8DPS30 uses a downward‑blasting wheel and closed abrasive circuit. Steel shot is accelerated by the blast wheel and impacts the surface, removing contaminants and creating a textured profile. The machine then recovers the steel shot and debris, separates reusable media from dust and spent material, and recycles the cleaned shot back into the system.

An EZ‑adjust control cage allows the operator to fine‑tune the blast pattern and intensity by changing the opening and direction in which shot exits the wheel. You can monitor blast performance using current draw on the ammeter, adjusting abrasive feed with a magnetic valve to achieve optimal cleaning power without overloading the system.

When connected to a compatible dust collector (such as the Husqvarna BDC‑23 or BDC‑1330, depending on region), the 1-8DPS30 operates virtually dust‑free, which is crucial for indoor work and environmental compliance.

Typical Applications and Surface Types

The Husqvarna Blastrac 1-8DPS30 Shot Blaster is designed for small to medium‑sized jobs where precise, controllable surface preparation is required. Typical applications include:

• Concrete floor preparation in industrial plants, warehouses, factories, and garages before applying epoxy, polyurethane, or other coatings.

• Cleaning and profiling residential and commercial garage floors prior to coatings or overlays.

• Asphalt surface prep for thin overlays or traffic coating systems, in appropriate conditions.

• Steel surface preparation (such as ship decks, tanks, or industrial platforms) where a clean, roughened profile is needed for protective coatings.

• Decorative concrete work where a uniform profile is required for microtoppings, stains, or other architectural finishes.

Because the machine is self‑propelled and compact, it is also frequently used along walls, in narrow corridors, and as an edge/blend machine alongside larger ride‑on or 10–15" shot blasters.

Productivity, Dust Control, and Ergonomics

The 1-8DPS30 is designed to maximize productivity while keeping operation simple. Its self‑propelled drive with steering‑handle controls allows the operator to focus on maintaining overlap and pattern rather than pushing a heavy unit. With typical production rates of 450–600 sq ft per hour on concrete, it can handle a surprising amount of work for an 8" machine.

Dust control is built into the design. A 3" dust hose connection and vacuum hose containment bracket help manage the hose and maintain suction when connected to a dust collector. When properly set up, the system strips, cleans, and profiles in one step while operating virtually dust‑free, which saves cleanup time and improves safety.

Ergonomic touches include the adjustable steering arm with fingertip controls, EZ‑grip handle on the shot screen tray, and improvements to the yoke attachment and self‑propelled motor assembly to make steering smoother. The compact footprint and 320 lb weight balance make it stable in operation but still manageable to load and unload with typical material handling equipment or ramps.
