FEATURES & HIGHLIGHTS

MAXIMUM CAPACITY, MAXIMUM UPTIME

The Harben® ET-180 is the tandem-axle step up from the E-180, built for crews who need more water on hand and fewer stops to refill. It runs the same proven 4,000 psi at 18 gpm performance and 2″ to 18″ line capacity, but doubles the tank to 750 gallons — a real advantage on city mains, extended runs, and jobs where every refill trip eats into your billable time. The tandem axle trailer and 49HP Kubota or Hatz diesel engine give it the strength to handle hard clogs, roots, grease, and full-system flushes back to back without slowing down.
