EMS EE615381681CN TO Japan

Going in to my first year using this fine bit of machinery and I'm astonished to say that it's great. It is for use with abrasives such as aluminium and silicon oxide powder. Built in antisuction system to prevent the risk of damage to air compressor sand powder. This is a great design.
