Vario jet Renfert – Automatic rotary sandblaster for dental laboratory
Référence: 2961.0000
Vario jet Renfert — Controlled power of automatic sandblasting
Automatic sandblasting delivers uniform results that manual blasting cannot maintain throughout a full working day.
While the machine operates, the technician can move forward with another case.
The Vario jet rotary sandblaster is ideal for economical, repeatable sandblasting on CoCr frameworks, cast structures, metal components and demanding laboratory work.
The real laboratory advantage: automatic blasting of metal frameworks
Processing multiple frameworks automatically optimizes laboratory productivity.
Place several frameworks in the rotary basket: all are blasted evenly.
Processing time remains close to manual blasting… but for multiple parts.
Blast a complete casting ring with several crowns or frameworks without supervision.
Pressure remains stable from start to finish.
During the cycle, the technician can layer ceramics, adjust or prepare another case.
Result: significant time savings and smoother production workflow.
The automatic cycle guarantees homogeneous surface quality without fatigue-related pressure variations.
Key features — precision, comfort and media control
Adjustable pressure, time and grit size depending on the material.
Only unusable fine dust particles are extracted.
Program selection via touch keypad.
Gauge display for immediate control.
Automatic activation with adjustable post-run time 5–30 sec.
Coated resistant viewing window + comfortable gloves with cotton lining.

FAQ — Vario jet Renfert Sandblaster
Why is automatic sandblasting more profitable in the lab?
Automatic sandblasting processes multiple parts with constant pressure and controlled timing.
During the cycle, the technician is not immobilized and can continue other steps.
Result: higher productivity, more consistent quality, fewer reworks.
Can several metal frameworks be blasted simultaneously?
Yes. The rotary basket allows homogeneous blasting of multiple frameworks in a single cycle.
You save significant time compared to manual piece-by-piece blasting while improving consistency.
Can an external suction unit be connected automatically?
Yes. The Vario jet can control an external suction unit with adjustable post-run time from 5 to 30 seconds.
This improves dust evacuation and cleanliness at the end of the cycle.
