MARK III – REGENERATIVE AIR STREET SWEEPER
The Liberty Mark III is a mid-sized regenerative air street sweeper designed primarily for curb- and-gutter type sweeping. It utilizes a full width, blast orifice style pickup head with 12-inch diameter intake and blast hoses with the intake on the right side. The Mark III is ideal for cleaning crowned streets and is equally effective for open pavement and construction sweeping. The Mark III is equipped with a high-dumping 4.35 cubic yard stainless steel hopper, 39-inch diameter vertical steel gutter broom(s) with hydraulic in-cab tilt, 105-gallon dust control system (optional 165-gallon) and is powered by a 67 hp turbo-diesel auxiliary engine.
The Liberty Mark III features a 10-bladed, backward-inclined blower fan constructed from Hardox® steel for maximum performance. The 30-inch diameter fan is backed by our 5 year / 5000 hour warranty against wear-out. The Mark III is mounted onto the highly maneuverable, 132-inch wheelbase Isuzu NQR chassis, which does not require a CDL to operate.
