This page compares the actual rpm that each fan operates at on high speed compared to the maximum allowed rpm per government regulations based on the size of the fan and thickness of the blades. If you are on the market for a high speed ceiling fan you are interested in high cfm performance. The standard 1200 mm fan will run at a certain speed that provides 300 350 rpm. Ul actually states the limitations based on the maximum allowed speed of the tip of the fan blade at 3200 feet minute for 3 16 thick blades and 2400 feet minute for 1 8 thick blades.

But what cfm is best. Cfm is dependent on the blade shape pitch and length and fan motor speed capacity.

In order to control the fan s speed the fan needs its own system of wires separate from that of the lighting element. The motor speed of a ceiling fan is denoted in rpm revolution per minute.

Although permanent magnet dc motors are also built with poles these poles don t impact speed like with ac motors because there are several other factors in play with dc motors. Good air delivery is identified at 205 230 cmm. Good cfm ranges from 4 000 to 5 000. Most of the designer fans come in colors like cherry oak walnut and rosewood.
