KEG’s Rotor Nozzles are an excellent tool for complete pipe cleaning when removing the remnants of grease, roots, and scale before TV inspections. It should be noted, however, that a Rotor is NOT a cleaning nozzle and should not be used in cleaning applications. Rotors are intended to remove the grease and sludge that remain in lines after an 80 percent cleaning has been accomplished. This sludge is the adhesive for the next clog to begin. KEG Rotor Nozzles are made with our unique water driven design and requires No Form of lubrication for maintenance and operation. Don’t use grease, oils, or other lubrication when performing maintenance on this nozzle.
