AL472100-40 | AL420 Wet Sandblast Kit Nozzle 1.40 mm Orifice

AL472100-40 — Sandblast Kit, 1.40 mm Nozzle is an Annovi Reverberi
AL420 Series wet sandblast kit that uses a 1.40 mm nozzle to deliver controlled abrasive
injection for paint removal, rust elimination, and aggressive surface preparation on metal, concrete, masonry,
and machinery. By using the pressure-washer’s water stream to entrain media at the lance, it suppresses dust,
keeps the work area clearer than dry blasting, and washes residue away as you cut through oxidation, scale, and
failing finishes.

Wet Sandblasting Performance

Venturi abrasive injection & water envelope

A venturi-assisted mixing path uses the high-velocity jet to pull media from the pickup line and blend it into
the stream, eliminating the need for external compressors or separate blast pots. The resulting plume delivers
consistent cutting energy while the surrounding water softens rebound, reduces airborne dust, and leaves a wet
slurry that is easier to contain and guide away from sensitive areas.

1.40 mm nozzle for balanced cut & control

The 1.40 mm nozzle is tuned for balanced abrasive draw and impact energy, giving steady removal
rates with fine control at the work surface. Operators can adjust standoff distance, travel speed, and media feed
to tailor the cut—faster passes for broad mill scale and light coatings, slower passes for stubborn rust bloom or
thick layers—while maintaining an even anchor profile that promotes primer and topcoat adhesion.

Setup & Operation

The AL472100-40 is designed for straightforward integration with compatible AR spray setups. Compact components
assemble quickly so crews can move from standard washing to wet sandblasting with minimal downtime and back again
when prep is complete. Setup is intuitive: verify the pressure-washer system is in good condition, connect the
sandblast attachment per orientation marks, route the pickup hose into a clean container of chosen abrasive, and
start with a controlled test patch to confirm media feed and surface response before scaling up.

During operation, gradual adjustments to nozzle spacing and traverse speed help lock in the desired profile.
Because the water stream envelopes the abrasive, visibility stays higher than with dry blasting and media is less
likely to escape beyond the intended work zone, especially on vertical surfaces or overhead work.

Construction & Reliability

Built for repeated cycling in damp, abrasive environments, the kit features robust hardware and smooth internal
pathways that minimize turbulence which could disrupt media flow. This helps prevent surging at the nozzle and
the uneven cutting action that wastes time and material. When paired with appropriate inlet filtration and clean,
correctly graded media, the system maintains a stable feed and produces a uniform surface finish across passes.

Typical Applications

• Restoring handrails, structural steel, and weldments prior to inspection or coating.
• Lifting graffiti and aged coatings from block, brick, and other masonry surfaces.
• Refreshing galvanized or painted parts where oxidation has undermined the finish.
• Scuffing concrete pads to open pores before overlays, sealers, or repair products.
• Knocking back corrosion on equipment frames, axles, and brackets without overheating parts.

Care, Media Handling & Safety

To keep performance high, rinse the attachment after use to purge fines, inspect the nozzle orifice and mixing
body for wear or buildup, and confirm that all seating surfaces remain clean and undamaged. Store the pickup hose
dry and covered, and check media for moisture before jobs to prevent clumping and bridging that can starve the
feed. Always follow best practices for wet blasting: wear appropriate PPE (eye and face protection, gloves,
hearing protection), secure the work area, manage runoff responsibly, and assess thin or compromised substrates
before blasting.
