The Coilhose Cannon Extreme High Volume Blow gun is designed to remove asphalt, stone, concrete, scrap metal, rock and other large pieces of debris found around construction sites, road/railroad maintenance work areas, sewer excavations and bridge repair locations. The Cannon features a safety nozzle that is OSHA compliant and delivers a concentrated force of air to a specific area so the debris can be directed toward the collection area. A "Power Assist" trigger minimizes actuation force and further helps control debris removal and clean-up. The Cannon also has 24- and 48-in. safety extension. A specially engineered multi-jet nozzle that utilizes the "coanda effect" is also available for the Cannon.
