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.

Frequently Asked Questions

What makes the OB 20 an orbital machine rather than a rotary?
The OB 20's pad moves in a non-directional orbital pattern rather than spinning around a central axis. This eliminates the directional swirl marks that rotary disc machines leave in floor finish, producing a more even result without cross-hatch re-buffing.
Can the OB 20 strip floor finish without chemicals?
Yes. At 3530 RPM with 180 lbs of downward pressure, the OB 20's orbital pad agitation breaks the bond between floor finish and the substrate without chemical strippers — producing 3,960 sq ft/hr of finish removal at 0.5 MPH.
What is the pad size on the OB 20?
The OB 20 uses a 20×14-inch rectangular pad — the elongated shape reaches into corners and along baseboards that round disc pads cannot access.
What optional accessories are available for the OB 20?
The OB 20 accepts a dust control kit (90054) with HEPA filtration, a 3-gallon solution tank kit (90051), and a 40-lb weight kit (90048) to increase downward pressure.
What is the noise level of the Tornado OB 20?
The OB 20 operates at under 64 dB — quieter than most standard floor machines — suitable for use in occupied schools, hospitals, and retail stores.
