Efficient Surface Treatment: 10 Gallon heavy-duty sand blaster is ideal for large-area surface treatment. It offers high sandblasting density, ensuring quick and efficient removal of rust and stain on iron frames, statues, car paint, or marble engravings. Working Pressure: 60-110 PSI. Air Consumption: 6-25 CFM. (Please prepare a 5.5KW air compressor separately) User-Friendly Design: Our sandblaster features a semi-automatic pull-up feeding port, easy to add and remove abrasives while preventing leaks or contamination. We recommend an abrasive capacity of 4.2 gallons, perfect for 60-100 grit media like coal slag, glass beads, walnut shells and more. (PLEASE NOTE: The used abrasive needs to be dry, or it will cause clogging) Heavy-Duty Sand Blaster Gun: Unlike the traditional brass ball valve sandblasting gun, our upgraded aluminum heavy-duty sand blaster gun is durable and easy to control
