Tornado OB 20 Orbital Floor Machine – 97600, 3530 RPM, 180 Lbs, 7920 sq ft/hr

OB 20 Orbital Floor Machine — 3530 RPM, 180 Lbs, Chemical-Free Finish Removal

The Tornado OB 20 (model 97600) uses a 1.5 HP TENV motor driving orbital motion at 3530 RPM with 180 lbs of total downward pressure through a 20×14-inch pad. It strips floor finish chemically-free at 3,960 sq ft/hr or scrubs at 7,920 sq ft/hr. Operates at under 64 dB. UL and CSA approved. Optional HEPA dust control, solution tank, and weight kits available.

Orbital Motion vs. Rotary Disc — The OB 20 Advantage

A rotary disc machine creates directional swirl patterns in floor finish from centrifugal pad motion. The OB 20's orbital motion moves the pad in a non-directional pattern that removes finish evenly without swirl marks, eliminating the need to re-buff in cross-hatch patterns. At 3530 RPM with 180 lbs of pressure, it removes floor finish without stripping chemicals — the pad agitation alone breaks the bond between the finish and the floor. Facility managers in healthcare and education use this for chemical-free strip cycles that reduce chemical handling risk and comply with green cleaning programs. The 20×14-inch pad size reaches into corners that round disc pads miss.
