DEC Blower System

Our industry has seen many innovations when it comes to air handling systems. From the standard PSC motors we’ve seen for many decades (and still do in some new equipment), on through several generation of ECM air flow systems.

A recent innovation to moving air efficiently is the DEC (Dual Efficiency Configuration) from Regal-Beloit Corp. 

In this type of blower system, the motor is not located in the blower inlet like it is in traditional squirrel-cage systems. (See Figure One)

The idea here is to eliminate the restriction that a motor creates when it is positioned in the path of the flow of air through the blower assembly. It’s all part of manufacturer’s efforts to achieve maximum efficiency.
