Dropping the speed with a cheap controller often trades that for a buzzing motor. A stepped transformer gives a clean, lower voltage at each step, so you can match \u003cstrong\u003eairflow\u003c\/strong\u003e to the room's heat and moisture load — and let a Can-Fan EC controller move between steps for you as the temperature changes.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCheck the fans' combined current is \u003cstrong\u003e4A or less\u003c\/strong\u003e — it is printed on each fan's label (a 10-inch Isomax 1,480m³\/h draws 0.9A, a 12-inch 3,260m³\/h draws 3.2A).\u003c\/li\u003e\n\u003cli\u003eMount the Satellite on a wall outside the tent, plug the fan or fans into its intake and outtake outlets and connect it to the mains.
