AL420-35-KIT-B | 3 GPM 3650 PSI Wet Sandblast Kit Heavy Duty Use

Overview

AL420-35-KIT-B — 3 GPM 3,650 PSI Wet Sandblast Kit is a very heavy-duty wet sandblasting package
engineered to transform compatible high-flow pressure washers into efficient surface-preparation systems for rapid,
controlled removal of paint, rust, scale, and persistent residues on metal, concrete, masonry, and other durable
substrates. Rated for up to 3 GPM at 3,650 PSI, it uses water’s momentum to accelerate abrasive
media at the work surface while suppressing dust, moderating heat, and reducing messy rebound—delivering cleaner
job sites and less secondary cleanup than dry blasting.

Why a 3 GPM / 3,650 PSI Wet Sandblast Kit

High-Output Wet Blasting for Serious Prep

AL420-35-KIT-B targets high-flow pressure washers, converting their hydraulic power into a concentrated
water/abrasive plume that cuts through coatings quickly. The combination of 3.5 GPM and 3,650 PSI supports fast
removal rates on heavy epoxies, industrial paints, corrosion, and scale while keeping the surface cool and
manageable for inspection and recoating.

Venturi Injection for Even, Repeatable Cutting

At the core of the system is a venturi-style injector that draws abrasive through the suction line, meters it
smoothly into the pressurized stream, and projects a coherent, high-velocity jet. This balanced metering prevents
surging, delivers steady cutting action, and helps produce consistent, repeatable surface profiles
from pass to pass.

Venturi System & Kit Architecture

Heavy-Duty, Corrosion-Resistant Hardware

Robust, corrosion-resistant construction with reinforced fittings and a wear-conscious nozzle design maintains
flow efficiency and sealing integrity during extended duty cycles. The blast head and injection body are built
to withstand continuous exposure to abrasive media, high-pressure water, and aggressive job-site environments.

Long Suction Hose for Continuous Media Draw

A long suction line supports uninterrupted draw from larger abrasive containers staged off to the side of the
work zone. Crews spend less time repositioning buckets or bags and more time cutting, which directly improves
footage-per-hour on big steel, concrete, or masonry projects.

Media Versatility & Process Control

Works with Common Non-Silica Abrasives

AL420-35-KIT-B works effectively with widely used non-silica media such as garnet, crushed glass, and baking
soda. Operators can match particle hardness, density, and size to the surface and the required finish—whether the
goal is an aggressive anchor profile on steel or a more moderate cleaning pass on concrete or brick.

AL420-35-KIT-B Simple Setup and Tuning

Setup is straightforward: attach the blast head to the pressure washer wand, place the suction probe into the
abrasive container, and bring the machine up to operating flow. The venturi generates suction automatically and
blends media evenly with minimal surging. Operators then tune performance by selecting pressure and standoff
distance, choosing a media grade that matches the target profile, and maintaining a steady traverse speed to
preserve plume coherence and control media consumption.

Operator Experience & Jobsite Benefits

Cleaner Jobsites with Reduced Dust & Rebound

Because water carries and cushions the particles, operator exposure to dust is reduced, rebound is gentler, and
spent media settles quickly for simpler containment and disposal. That balance of impact and control is especially
valuable in plants, shipyards, bridges, rail yards, and urban jobs where dust suppression and site cleanliness
are mandatory.

Consistent Profiles, Fewer Passes

The kit’s efficient hydraulic path and balanced metering concentrate energy at the nozzle so compatible pumps
deliver removal rates that translate into fewer passes to bare substrate and more uniform anchor profiles for
primers, sealers, and topcoats. Field and shop crews alike benefit from faster prep cycles and more predictable
finishing results.

Maintenance & Best Practices

Flush, Inspect, and Protect Wear Surfaces

Routine care keeps performance consistent. After blasting, flush the head and suction line with clean water to
remove residual grit, inspect the orifice and wear points, and store the assembly dry to protect sealing surfaces.
Periodic checks of threaded joints and hose condition help keep the kit leak-free under pressure; replacing worn
orifices at sensible intervals preserves cutting power and avoids unnecessary load on the pressure washer.

Media Handling for Reliable Flow

Good media hygiene pays dividends: keep containers covered to prevent moisture ingress that causes clumping, strain
out oversized fragments that could impede flow, and use clean, compatible abrasives for predictable venturi
metering. Stable media quality supports smooth suction, uniform plume density, and repeatable surface results from
job to job.

Key Features of AL420-35-KIT-B

• Heavy-duty wet sandblast kit rated  3 GPM at 3,650 PSI for high-production surface prep.
• Venturi-style injector draws and meters abrasive smoothly into the water stream for even cutting.
• Long suction hose supports continuous draw from larger media containers away from the blast area.
• Corrosion-resistant, reinforced construction with wear-focused nozzle design for extended duty cycles.
• Compatible with common non-silica abrasives including garnet, crushed glass, and baking soda.
• Water-assisted blasting reduces dust, moderates heat, and softens rebound compared to dry blasting.

Priority Applications

Industrial, Fleet & Infrastructure Work

• Stripping epoxy and heavy coatings from steel structures and machinery.
• Removing oxidation and scale from equipment frames, tanks, and process skids.
• Fleet and rail maintenance: frames, decks, and hardware where dust control matters.
• Marine and shipyard work: scouring marine growth and corrosion from hardware and components.
• Concrete and masonry prep: graffiti removal, sealer and paint stripping, and profile creation for new coatings.

Bottom Line

AL420-35-KIT-B Wet Sandblast Kit combines a 3 GPM / 3,650 PSI rating with venturi
injection, a long suction hose, and heavy-duty construction to turn compatible pressure washers into efficient,
high-control coating-removal systems. It delivers the blend of power, process control, and cleanliness that
professional field and shop crews need when dry blasting is impractical and surface prep still has to move fast.
