The commercial machines are designed to provide a strong supply of slurry to the gun and a larger volume of air. They also agitate the media/ water more efficiently. The pumps can range anywhere from 1.5kW up to 11.5kW . This all adds up to a more powerful machine that will process parts more efficiently and have a greater range than those with small submersible pumps and smaller air jets. Parts are more robust and some have features to minimise operator error (useful when you have a variety of workers using the machine – some with a lower “care factor” than yourself)
