The 40x40x56mm dual-impeller, dual-motor fan is engineered with redundancy to protect against fan failure and to produce effective airflow performance against high system pressures. As a result, the fan offers a 90% improvement in CFM and PQ curve in comparison to a similar size single blade fan.

The fan consists of two independent motors and incorporates a 5-blade fan and a 3-blade fan.
