Renfert Basic Quattro IS 4-silo sandblaster for dental microblasting
The Renfert Basic Quattro IS 4-silo is a professional dental sandblaster designed for laboratories that use several blasting protocols every day. Its Immediate Stop technology cuts the flow of abrasive cleanly to reduce over-blasting and protect delicate areas.
This 4-silo version allows several grain sizes or abrasives to be organised directly on the same workstation. It is particularly suitable for versatile laboratories alternating between surface activation, selective cleaning, divesting, mechanical preparation and localised finishing.
4-silo dental sandblaster for versatile laboratories
In a dental prosthetics laboratory, a 4-silo sandblaster improves organisation, speed and consistency when several materials are processed during the same day. The Renfert Basic Quattro IS helps separate protocols without constantly changing abrasive or grain size.
This configuration is ideal for laboratories that need fine aluminium oxide for surface activation, a more aggressive abrasive for divesting, and separate settings for cleaning or mechanical preparation. The workflow becomes smoother, cleaner and more reproducible.
The independent pressure setting for each silo makes it possible to organise the blasting station as a true surface-preparation centre. The dental technician saves time, reduces setting errors and maintains better control over surface finishes.

Why choose the Basic Quattro IS 4-silo version?
The 4-silo version of the Renfert Basic Quattro IS is intended for laboratories that want to go beyond a standard blasting station. It provides several abrasives immediately available, with dedicated settings and better separation of protocols.
This organisation is valuable when the same laboratory works on prosthetic intaglios, metal surfaces, ceramic parts, resins or restorations from investment materials. Each silo can be assigned to a specific grain size and application to reduce approximations.
The Immediate Stop system complements this versatility with a clean shut-off of the abrasive flow. The dental technician therefore keeps better control over localised areas, thin margins and delicate preparations.
Technical blasting advice
With a 4-silo configuration, the best approach is to assign each silo to a clearly defined use: fine activation, routine cleaning, more powerful divesting and specific mechanical preparation. This method avoids changing abrasive during the working day and secures the settings.
To obtain a consistent result, it is important to keep a stable distance between the nozzle and the workpiece, adapt pressure to the material and work with dry abrasive. Efficient suction remains essential to preserve visibility and limit chamber contamination.
Laboratory workflow: organisation and productivity
The 4-silo version provides real comfort for laboratories that handle varied work. The blasting station becomes faster to use because each grain size can remain ready for its dedicated protocol.
The laboratory gains productivity, but also working safety. The risk of confusion between abrasives is reduced, settings are more consistent and surface finishes become more reproducible across series.

Laboratory tip
On a 4-silo version, assign a precise role to each silo and always keep the same organisation: fine activation, cleaning, divesting and mechanical preparation. This prevents grain-size errors and speeds up workflow changes.
For sensitive areas, start with low pressure and gradually increase it if necessary. This approach reduces rework, protects thin margins and improves the reproducibility of surface finishes.
