The RENFERT Twister Venturi is a high-torque Vacuum mixer that builds Vacuum from compressed air via Venturi nozzle — no internal pump, no oil, no consumable diaphragms. Adjustable Vacuum (80% / 100%) lets the operator dial back pressure for plasters and silicones that would otherwise boil. Made in Germany, the chassis can be wall-mounted or paired with the optional RENFERT stand to convert to a bench unit. Speeds 100–450 rpm, motor torque high enough to homogeneously process the largest investment and alginate batches. Bi-voltage 100–240 V means it works on any line worldwide.
