Agitators Designed and Manufactured by AFX Holdings

Before the development of folding impellers, applications such as these were approached by using impellers with fixed blades that had a diameter small enough to pass through the vessel opening. This meant that the agitator would run at speeds much higher than those whose impeller's DT ratios had been created to meet the desired specification Get price
