Model Overview

SMXD-HT 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. This HT (high temperature) model can provide emergency heat and smoke ventilation in the event of a fire, which can provide valuable time to people exiting or emergency personnel. The SMXD-HT is UL Certified to exhaust heat and smoke in emergencies [500℉ (260℃) for 6 hours and 572℉ (300℃) for 2 hours].

SMXD-HT 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-HT can be used in parking garages, commercial buildings, warehouses, food retail centers, and educational buildings.
