The Alphajet cleaning nozzle from USB - Sewer Equipment Corporation is designed to clean grease, sludge and crusts from lift stations and manholes prior to rehabilitation. It is actuated by water coming from the pressurized hose of the jetter truck. Four driving nozzles cause 360-degree controlled rotation in a horizontal plane, eliminating the need to cover the manhole. The horizontal rotation only allows for observation of the cleaning progress. The body requires no lubrication or replacement of internal mechanical parts within the first 12 months of operation, making it user friendly. Driving nozzles can be extended to accommodate various sizes of manholes/lift stations. 866/408-2814; www.usbsec.com.
