Basic Overview: Arrangement 1 Belt Driven Fan

What is an Arrangement 1 Fan?

Fan arrangements, based on AMCA standards, define the way a motor drives the fan, and how the motor and other drive components mount to the fan. An Arrangement 1 Fan is a belt-driven fan with the motor mounted separately. In general, a belt driven fan is connected to the fan’s motor via one or more belts and the fan and motor are mounted on a unitary steel base.

The Arrangement 1 Belt Driven Fan offers several benefits in the right application, including:

  • Variable Speed
  • Less Wear & Tear on the Motor (for some applications)
  • Common Mounting Base

Components of an Arrangement 1 Fan

In order for an Arrangement 1 Fan to operate properly, it must include these parts:

  • Fan Assembly (wheel, housing, & pedestal base)
  • Shaft
  • Bearings
  • Motor
  • V-belt Drive
  • OSHA Guards
  • Unitary Base

  • Direct Driven: Arrangement 4, 4V, and 8
  • Belt Driven OR Direct Driven: Arrangments 3, 7, and Plug
