Blasters Certified Pre-Owned (CPO) Equipment offers a brand-new way of looking at used equipment. During our 140-point refurbishment program, all of our equipment is inspected and refurbished to Blasters’ factory standards. After the completion of the unit, it is fully tested and certified by one of our factory technicians running at its designated full pressure and volume. Once completed, the water blaster is ready for use and detailed for shipping.
