Model Overview

SMXD series is a direct drive mixed flow fan specially designed to maximize the airflow performance by acting as a hybrid between an axial and centrifugal fan. They produce a great amount of air while being able to handle higher pressures. It is more efficient and quieter than comparable tubular centrifugal fans. These fans can be used in exhaust, supply or return air applications.

SMXD features a direct drive motor paired with AC Drives to allow the flexibility to control the speed of airflow. This feature has no transmission losses associated with belt drives and features less maintenance.

Designed with high efficiency and low sound as a priority, SMXD can be used in parking garages, commercial buildings, warehouses, food retail centers, and educational buildings.
