The Koblenz SP-2815 N is the wide-body version of the Accelerator: a 14 x 28 inch rectangular orbital floor prep machine for crews stripping and recoating large open floors on a clock. The 28 inch head covers roughly 40 percent more floor per pass than the 20 inch model, which is what turns a two-night gym or big-box strip into a one-night job. Building service contractors, school districts, warehouse and retail facility teams and flooring contractors run it for chemical-free finish removal, deep scrubbing, screening and sanding.
Built for
- Large-area strip and recoat. Gyms, cafeterias, corridors, retail sales floors and warehouse aisles where a 20 inch head costs you passes.
- Chemical-free finish removal. Runs dry, so there is no stripper to mix, no slurry to wet-vac and no disposal.
- Deep scrub without a full strip. Take off the top coats, leave the base, recoat the same shift.
- Screening and sanding wood. The oscillating pattern avoids the swirl a rotary can leave on gym and stage floors.
- Corners and edges. The rectangular head squares into corners that round pads always leave for hand work.
A 1.5 HP induction motor with sealed ball bearings drives the head at 3500 RPM. The heavy cast iron chassis supplies the downpressure, so pad contact stays even across the full 28 inch width instead of depending on how hard the operator leans. A cast aluminum pad driver, two-piece chromed 13-gauge steel handle, 50 ft 14-gauge three-wire grounded cord and two 5 inch non-marking wheels complete the machine, and it is backed by a 5 year limited warranty.
Orbital prep has become standard in facilities that cannot shut a floor down. Because the machine produces dust rather than slurry, the area does not have to be roped off for a wet strip, and crews report far less back and shoulder fatigue than fighting a rotary through old finish. The trade-off is size: at 28 inches wide the SP-2815 N is a big-floor machine. If your work is mostly restrooms, small classrooms and tight corridors, the 14 x 20 inch SP-15 N is the better fit.

Frequently asked questions
How much faster is the 28 inch head than the 20 inch?
The SP-2815 N covers a 28 inch path versus 20 inches on the SP-15 N, roughly 40 percent more floor per pass. On large open areas that difference usually decides whether a strip-and-recoat fits in one shift.
Does it strip finish without chemicals?
Yes. Run dry with a prep pad it abrades finish off as dust instead of dissolving it, so there is no stripper solution and no slurry to recover. It also works wet for deep scrubbing and screening.
Is it hard to control compared to a rotary machine?
It is easier. The head oscillates rather than spinning in one direction, so the machine does not pull to one side and the operator is not balancing torque. Most crews are productive with it on the first night.
What surfaces can it be used on?
VCT, sealed concrete, terrazzo, ceramic and wood, with the pad grade matched to the surface. On wood it is commonly used for screening between coats.
Will it fit through a standard doorway?
The head is 28 inches across the working width. Measure your tightest doorway and turn radius before ordering. For buildings with narrow doors and small rooms the 14 x 20 inch SP-15 N is the safer choice.
