Information on maximum revolutions per minute for BOLA stirrer shafts
BOLA Gassing Stirrer with 4 Blades
Material: Temperature resistance: Chemical resistance: Vacuum: autoclave: PTFE -200 °C to +250 °C +++ universal suitable 121°
FDA conform Product description:
PTFE-jacketed stainless steel shaft, propeller with four blades completely made of PTFE. Clockwise rotation of the shaft produces a vacuum behind the stirrer blades. By this vacuum, the gas is transported from the gas compartment through the hollow shaft and into the product. The rotation speed depends on the fluid level and the immersion depth: e. g. 430 rpm are necessary at 150mm, and 690 rpm are necessary at 350 mm. The length of the shaft and the suction pipe can be adapted individually. Minimum one baffle is imperative for proper operation (Cat.No. C 490-..). Universal chemical resistance since the product is only exposed to PTFE.
Applications:
Reduced reduction times compared to stirring without gassing due to high aeration of the product. Strong radial flow, ideal for gassing of liquids.
