have to consider several important factors before making your 
purchase. While some of the portable sand blasting machines 
operate in an open environment, others include an attached 
cabinet that houses the nozzle head and handles the cleaning 
process. These units usually have a 5-meter blast hose and are 
suited for freestanding objects. On the other hand, if you are 
working on a large or bulky object, you will want to invest in a 
sandblasting cabinet.
