The Basic Quattro IS dental sandblaster is designed for the dental laboratory: precision sandblasting, surface activation, selective cleaning and controlled devesting. The Immediate Stop (IS) technology instantly cuts the abrasive flow to limit over-blasting, improve repeatability and preserve sharp margins on delicate areas.
20 L chamber — fluid movements
LED 4800 lux — visibility
Pressure per tank — fast workflow
IS — instant jet stop
Professional micro-blasting: control, visibility and repeatable results
In dental technology, a lab sandblaster must deliver a stable jet, clear visibility and reliable settings. The Renfert Basic Quattro IS meets daily needs: surface preparation before bonding, localized blasting in fissures, framework cleaning and finishing. The immediate stop reduces residual flow and secures critical zones (contacts, margins, embrasures).
PerfectView concept
- LED 4,800 lux: detail visibility and visual comfort.
- Large chamber: freedom of movement and stable jet paths.
- Integrated air gun: quick cleaning between runs.
- Protected viewing window: long-lasting visibility.
Key advantages in the dental laboratory
- Independent pressure per tank: rapid protocol switching.
- Immediate Stop: sharp jet cut-off to avoid over-blasting.
- Abrasive savings: reduced waste, cleaner chamber.
- Upgradeable 2 → 4 tanks: multi-material versatility.
Applications (indications)
- Surface activation before bonding / coating.
- Selective cleaning: fissures, embrasures, margins.
- Controlled devesting of delicate restorations.
- Mechanical preparation of retention areas.
Quick user guide (best practices)
- Select suitable abrasive + grain size.
- Adjust pressure per tank and test.
- Maintain constant distance and angle.
- Purge lines if needed.
- Clean chamber, window and suction system.

FAQ — Basic Quattro IS
Does the “IS” technology improve daily precision?
Yes. The Immediate Stop system provides a sharp jet cut-off,
limiting residual flow and reducing over-blasting.
This is especially useful for localized blasting to preserve
sharp margins and ensure more repeatable results.
Which grain size / pressure combinations are recommended?
For surface activation: alumina 25–70 µm
at 2–3 bar.
For devesting: 70–250 µm
at 4–5 bar.
Always validate on a test piece and follow manufacturer guidelines.
How to maintain perfect chamber visibility?
Replace window protection when contrast decreases,
use the air gun regularly,
ensure proper suction,
and keep tanks dry to prevent clogging.
