150mm Normal Profile Centrifugal Inline Fan (ebm-papst Variable Speed R3G190 EC Motor)

AC Motors vs EC Motors

AC motors are cheaper than EC motors but still provide excellent performance. They are very quiet during operation and move large volumes of air through ducting. They operate at one fixed speed where they are most efficient. 

In real world use, EC motors provide even higher air flow, are extremely quiet during operation, are capable of silent operation at reduced fan speeds, have smoother fan rotation, and consume almost no power at reduced fan speeds. EC motors have adjustable speed and are very efficient at all speeds.

Normal Profile Fans vs Low Profile Fans

Normal Profile is our standard fan configuration. Normal Profile fans are round with a diameter of 342mm. Normal Profile fans are recommended for most installations.

Low Profile fans are available for shallow installations where access is limited. Low Profile fans are oval with a width of 340mm and a height of 217mm. The smaller footprint means that air flow is reduced by about 10%, but they still provide exceptional performance as their shallow environments generally have less cubic volume to ventilate.
