When buying used sandblasting equipment, it’s important to inspect hoses, nozzles, and connections for wear and damage. Look for equipment that has been well-maintained and avoid dirty or greasy tools. Check the motor, compressor, and reserve air tank of commercial-grade units, and avoid equipment that shows signs of neglect or damage.
Some used sandblasting equipment will have severely worn parts that may not be easily identifiable to the average person. You may want to buy only used blasting equipment that you can use or see working before making a purchase if you want to be sure you’re getting the best working equipment.
Hoses, nozzles, and other components can turn out to be a good deal for what appears to be no bargain after the cost of replacing these parts. The high abrasiveness of the blasting medium can often wear the nozzle, causing an irregular spray pattern and reduced effectiveness when blasting. You will also need to examine all hoses and connections when purchasing used sandblasting equipment. This can save you from buying pipes that crack or are broken when purchased. It’s also never a good idea to buy a dirty set of tools or equipment.
The most reputable workers treat their tools properly. If you see very dirty or greasy air hoses or used blasting equipment, you may not be getting the best deal. You’ll need to select used sandblasting equipment from only the most meticulous of owners if you want to be sure you’ve purchased only the best. Hoses that are kinked or appear to have layers of paint or another type of dirt on them should not be purchased as they could be damaged under the dirt or from the twisting.
If you purchase a large commercial-grade sandblasting unit complete with an air compressor, you’ll need to inspect the motor, compressor, and reserve air tank to make sure you’re choosing the best used equipment. Most large sandblasters use a diesel-powered air compressor. The total hour meter commonly placed on the engine should be checked to determine the expected life left in the engine. This figure can be compared to a service manual to identify repairs needed and repairs expected. You can verify this against receipts for all maintenance completed on the engine by the previous owner.
A simple test is to pull the drain plug on the reserve air tank and watch for the water to run out. A high volume of water indicates, in most cases, poor maintenance. Extremely rusty water can indicate a stock air tank that is ready to rust and should be avoided. One of the best quality indicators of used blasting equipment is seen in the appearance of the equipment. Dirty, damaged, or neglected equipment should probably be avoided, and consideration should be given to purchasing nice, clean, well-maintained used sandblasting equipment.
