A Derale 10-inch fan typically draws about 5.3 amps running for the Tornado 10" model. Another Derale 10-inch high-output model draws 9.2 amps , so the exact number depends on the specific fan version.

Quick Scoop

  • Derale 10" Tornado fan: 5.3 amps.
  • Derale 10" High Output fan: 9.2 amps.
  • Startup surge can be higher than the running draw, so fuse and wiring size should account for that.

Practical note

If you’re sizing wiring or a fuse, use the exact fan part number rather than just “Derale 10 fan,” because the amp draw varies by model.
