The unique double impeller heightens torque by up to 50 percent, and improves torque stability – including under high levels of strain. The device’s steady removal power promotes silky smooth preparation, with substantially greater precision.
Even the Ultramini series, with their only nine millimeter in diameter heads, deliver a unique preparation power ranging up to 20 watts.
The air from the drive nozzles drives the primary impeller. The exhaust air is channeled via ribs and drives the second impeller. The result: extremely high and steady torque, even under a load.
