Can Openers for the Commercial Restaurant Industry are classified under two categories: Manual and Electric. Manual Commercial Can Openers are available either as the hand-held "Easy Crank" style or the "Slide Bar" table mounted style, both by Edlund and Nemco. Edlund makes the standard #1 and #2 styles that have been around for decades, as well as the S-11 and U-12 series of Can Openers. The Edlund S-11 Can Openers are dishwasher safe with a wide open design that allows water to pass right thru for a thorough wash. The Edlund U-12 is designed as a "Quick Gear Change" with a pull pin for easy blade replacement. Nemco makes the "Gearless" Can Opener that eliminates metal shavings and has a cutter module for a quick change out. As for the electric models, Edlund manufactures a variety of powered Can Openers that are rated as to how many can be opened per minute and per day.
