Stirrer shafts made of PTFE-jacketed stainless steel and the propeller with four blades completely made of PTFE.

• Chemical resistant
• Temperature resistance from –200 to +250 °C
• Rotation speed depends on the fluid level and the immersion depth
• Creates strong radial flow, suitable for gassing of liquids
• With chucking diameter of 8 mm

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.
