Publication number: 20210354266Abstract: An abrasive blasting system and associated methods are disclosed. The abrasive blasting system includes a blast enclosure that receives a component to be blasted by an abrasive media. A dust collector is fluidly coupled to the blast enclosure and collects the dust from the blast enclosure generated by the blasting of the component by the abrasive media. The dust collector includes a filter and a fan having a motor. The filter is disposed upstream of the fan. The fan draws air and dust from the blast enclosure into the dust collector and draws air through the filter to separate the dust from the air. A sensor monitors a condition of the abrasive blasting system and generates a condition signal corresponding to the condition. A controller receives the condition signal and controls the fan based on the condition signal.Type: ApplicationFiled: May 14, 2021Publication date: November 18, 2021Inventors: Ernest Gale Shafferkoetter, Anthony James Regna, Donald Bradley Maisel
