Model Overview

Model SMXDK mixed flow fans are inline ducted fans that can be used in exhaust, supply, or return air applications. Mixed flow fans act as a hybrid between axial and centrifugal fans. Meaning, they produce a lot of air such as axial fans, but they can handle higher pressures like centrifugal fans. When these technologies come together, the fan ends up being more efficient and quieter than similar tubular centrifugal fans.

S&P is taking efficiency a step further by focusing this design around efficient direct drive motors, which can be paired with AC drives or EC motors to adjust fan speed. The ability to control the speed allows the fan to hit multiple fan selection points similar to how a belt drive fan would be applied. Another couple of advantages with this is the lack of transmission losses associated with belts, and less maintenance that is associated with belt drive units.

Mixed flow fans work great in many applications where high efficiency and low sound are a priority. Some of those include: parking garages, commercial buildings, warehouses, food retail centers, and educational buildings.
