Fuji air tools manufactures pneumatic stirrers [model apam-3-4ts] that can be mounted on a flange. These stirrers have free speed of 500rpm. They have stainless steel rod of four blades. The pneumatic stirrers can be used continuously for stirring of paints, chemicals, fluids, etc. Being pneumatic, they are completely flameproof, shock-free and spark-free. If there is an excess load during stirring, the stirrers will just stall temporarily, and when the excess load is gone, they will start working normally, without any damage. Exhaust air can be left to the atmosphere through a silencer, or it can be piped away to another location. Applications are in paint industry, pharmaceutical industry, processing and petrochemical industry, etc.
