Sanyo Denki has been developing fans for a wide range of applications and usages. There are many kinds of fans, but the main ones in the industry are as follows: single axial, counter-rotating, blower, and centrifugal fans. Each type of fan comes with a difference in PQ (static pressure-volumetric characteristic) curves and application usage. To understand these differences is to gain a large understanding of how these types of fans operate and how to read the fan’s PQ curves and specifications. This knowledge will help allow the user to build their system with the appropriate amount of power consumption, sound pressure levels, and appropriate fan selection without exceeding their thermal needs.
