Reconditioned Pioneer Eclipse PE 420GP 21" Propane Burnisher
Our Take (from the SES Sales Team)
“The PE 420GP is a propane machine that does more than burnish. Its heavy-duty diamond driver takes standard 3-inch diamond pads, so it grinds and polishes concrete and stone at 1,000 rpm, then switches to 1,500 rpm for high-speed burnishing on finished floors. Pad pressure adjusts from 85 to 180 lb, so you can go light for a polish pass or put weight down for grinding.
Propane means no cord and no battery run time to plan around, which suits large warehouses, retail floors and big open concrete. Pioneer Eclipse rates it at up to 25,000 square feet an hour burnishing. A dust port connects to a vacuum hose for dry grinding, and the water supply keeps dust down on wet work.
SafeStop and SAFR low-CO technology are built in, but this is still a propane engine: plan for ventilation and use it where propane equipment is allowed.”
