Greenlee’s updated 690 Power Fishing System (Model 690-15) features a newly designed motor, larger 8” wheels, a transport handle and a longer 15” hose for improved maneuverability around the jobsite. Both the new motor unit (60-RM) and the replacement tank unit (690-RT) are compatible with all 690 models from 1988 to present. The industrial two-stage motor unit features 7.2” fans designed to maintain consistent pressure. This design enables the piston and line weight to travel further than a typical consumer vacuum unit. The 690-15 also features a 1/4”-thick tank design.
