Description
BOLA Gassing Stirrer with 4 Blades, PTFE
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. Universal chemical resistance, the product is only exposed to PTFE.
Reduced reduction times compared to stirring without gassing due to high aeration of the product. Strong radial flow, ideal for gassing of liquids.
BOLA Slip-On Baffle, PTFE
Completely made of PTFE, supporting ring made of PFA. The baffle can be mounted at any position on a temperature probe or a solo stirrer shaft. Design based on DIN 28131. Universal chemical resistance, the product is only exposed to PTFE.
Prevents rotation of the stirring products and provides an axial flow for better mixing. For gassing stirrers, one baffle is imperative.The position in the reactor can be optimized with BOLA Swivelling Screw Fittings.
