Renfert Basic Quattro IS 2-tank dental sandblaster for precision microblasting
The Renfert Basic Quattro IS is a professional dental sandblaster designed for laboratories requiring precise, clean and reproducible blasting. Its Immediate Stop technology cuts the flow of blasting media sharply to reduce over-blasting and protect delicate areas.
This 2-tank version allows the use of two different grain sizes and remains upgradeable according to the laboratory’s needs. It is suitable for dental microblasting, surface activation, selective cleaning and controlled devesting protocols.
Professional dental sandblaster for precise microblasting in the laboratory
In a dental prosthetics laboratory, blasting quality directly affects adhesion, surface cleanliness and the consistency of finishing procedures. A high-performance sandblaster must provide a stable jet, clear chamber visibility and reproducible settings to secure daily protocols.
The Renfert Basic Quattro IS provides precise jet control, comfortable visibility and a chamber volume that allows natural working movements. It meets the needs of laboratories looking to improve surface quality without complicating the organisation of the blasting workstation.
It is particularly relevant for laboratories alternating between several protocols: fine aluminium oxide for surface activation, stronger abrasive media for devesting, localised cleaning or mechanical preparation. Independent pressure adjustment per tank makes it easier to switch from one application to another while maintaining full control.

Why choose the Basic Quattro IS?
The strength of the Renfert Basic Quattro IS is not only its blasting power, but also its ability to deliver clean, controlled and reproducible work. For a dental laboratory, this precision is essential when treating delicate areas without rounding edges, over-blasting a surface or increasing the number of corrections.
The Immediate Stop system makes a real difference in everyday use, as it reduces residual abrasive flow after releasing the control. This clean shut-off gives the technician a greater sense of control, especially on intaglio surfaces, localised preparations and filigree workpieces.
This sandblaster is also relevant for laboratories that want to structure their protocols. By dedicating each tank to a specific abrasive, the team saves time, reduces setting errors and improves the consistency of surface finishes.
Technical sandblasting tips
For fine surface activation, it is recommended to work with an appropriate grain size, moderate pressure and a consistent distance between the nozzle and the workpiece. The result should remain homogeneous without hollowing the surface or creating excessive alteration.
For devesting or more energetic cleaning, use a coarser abrasive and gradually increase pressure after validation on a test piece. Efficient extraction and properly dry blasting media are essential to prevent clogging and maintain a stable jet.
Laboratory perspective: precision, visibility and workflow pace
The 20 L chamber facilitates continuous movements and reduces the feeling of restriction when blasting larger components. LED lighting improves the visibility of contours, embrasures and already-treated areas.
Workflow becomes smoother when each tank is dedicated to a specific grain size. The laboratory saves time, limits protocol errors and maintains better consistency across batches of work.
Practical use cases: pressure, abrasive and laboratory objective
| Use case | Recommended abrasive | Indicative pressure | Desired objective |
|---|---|---|---|
| Fine activation before bonding | Fine aluminium oxide according to material protocol | Moderate pressure | Create a regular surface without excessive abrasion. |
| Cleaning intaglio surfaces | Fine to medium abrasive depending on the material | Progressive adjustment | Clean the area without altering the fit. |
| Devesting components from investment material | More energetic abrasive | Higher pressure after testing | Remove residues without weakening details. |
| Preparing metal areas | Suitable corundum or aluminium oxide | According to alloy protocol | Prepare a clean and homogeneous surface. |

Compatibility
The Basic Quattro IS can be integrated into blasting protocols for metal frameworks, prosthetic intaglio surfaces, resin components, ceramic surfaces or preparations before bonding, according to material recommendations. The choice of abrasive, pressure and distance remains decisive in preserving surface quality.
Installation
The unit must be connected to a clean, dry and stable compressed air supply. For regular use, it is important to combine the sandblaster with suitable extraction in order to maintain visibility, reduce dust and preserve the cabinet.
Maintenance
Proper maintenance involves checking the nozzles, keeping the viewing window clean, monitoring seals and using dry abrasives. A clean cabinet helps maintain readable, regular and more comfortable blasting every day.
Laboratory tip
Reserve each tank for a specific grain size and clearly note the associated protocol: material, pressure, distance and approximate duration. This method avoids approximate settings between cases and greatly improves reproducibility.
For sensitive areas, always start with lower pressure and increase gradually if necessary. This approach reduces corrections and protects fine edges, embrasures and surfaces that have already been adjusted.

FAQ — Renfert Basic Quattro IS
Is Immediate Stop technology really useful in a dental laboratory?
Yes, it is particularly useful when the dental technician works on delicate or localised areas.
The clean jet shut-off helps reduce over-blasting and preserve cleaner edges, especially on intaglio surfaces, embrasures and delicate components.
This technology also improves the sense of control during handling.
It allows more precise work and helps reduce corrections caused by excessive abrasion.
Which abrasives can be used with the Basic Quattro IS 2-tank version?
The 2-tank configuration usually allows one tank to be reserved for a fine grain size and the other for a higher grain size.
This makes it easier to alternate between surface activation, selective cleaning and devesting.
The exact choice depends on the material being treated and the manufacturer’s protocol.
It is recommended to validate pressure, distance and blasting duration on a test piece before working on a final case.
Which dental sandblaster should be chosen for a versatile laboratory?
For a versatile laboratory, priority should be given to a stable, readable sandblaster that is compatible with multiple abrasives and easy to organise on a daily basis.
The Basic Quattro IS 2-tank version is relevant because it already separates two grain sizes while keeping the possibility of upgrading to a more complete configuration.
If the laboratory works with many protocols, the 4-tank version may become more comfortable.
For standard microblasting, surface activation and cleaning, the 2-tank version remains a highly coherent professional base.
How can visibility be preserved inside the blasting chamber?
Visibility depends on the condition of the viewing window, the extraction system and the overall cleanliness of the chamber.
The window should be replaced or protected as soon as contrast decreases, especially during intensive use.
Suitable extraction and dry abrasives reduce deposits and clogging.
Regular maintenance helps preserve efficient lighting and a comfortable field of vision.
What pressure should be used for precise dental sandblasting?
Pressure must be adapted to the material, grain size and blasting objective.
Moderate pressure is preferable for fine surface activation, while devesting may sometimes require a more energetic setting.
The most important point is to keep a consistent distance and validate the result on a test area.
This method reduces surface condition variations and improves reproducibility.
Can the Basic Quattro IS be used for zirconia, metal or resin?
Yes, it can be integrated into different laboratory protocols, including metal surfaces, prosthetic intaglio surfaces, certain resin components or ceramic surfaces, provided that the recommendations specific to each material are followed.
The choice of abrasive and pressure remains essential to avoid overly aggressive abrasion.
For zirconia, metal or resin, it is advisable to work with parameters validated by the material manufacturer.
A test piece helps confirm the surface condition before use on a final restoration.
