Never allow lack of information to prevent you from selecting the proper blast machine for your application. Read the information that follows and it will help you select a machine right for the job. Cleaning speed varies with the abrasive gun size or compressed air usage. What takes a 20 CFM compressor 1 hour to process, takes a 40 CFM compressor 15 minutes, takes a 80 CFM compressor 5 minutes. Each abrasive gun size operates at a temperature that increases in frictional heat as the abrasive gun increases in size.
Larger guns generate more heat during the blast which greatly reduces the processing time.
They lack the support equipment to operate with the larger blast guns. Machines, costing more, can compress 8 hours of processing into less than 1 hour by using a larger blast gun. If unlimited compressed air is available, the production type of machinery can pay for the increased cost by saving labor at an almost geometric rate. Light duty machines are excellent choices when the parts are small and continuous operation is not required. See our Internet Special .
