The Ring-O-Matic 550 dual-pump combination sewer line jetter and vacuum excavator gives contractors and municipalities the advantages of a dedicated combination jetter/vacuum truck in the more versatile footprint of a compact trailer unit. It fits into spaces too confined for truck-mounted combo rigs, yet it can clean sewer lines up to 20 inches in diameter. Powered by an 81 hp CAT turbo diesel, it has a 1,000 cfm blower and can deliver 27 gpm at 2,700 psi up to 400 feet with its 3/4-inch jetter hose. The trailer’s axles are rated to 16,000 pounds, allowing the 550-gallon spoils tank and 500-gallon freshwater tank to be easily pulled behind a suitably equipped 3/4- or 1-ton truck. 800/544-2518; www.ring-o-matic.com.
