CHARLOTTE, NC – High-efficiency Rosenberg EC backward curved centrifugal fans are an ideal performance and function fit for a wide range of HVAC designs, especially evaporator applications.

These rugged backward curved units are available with or without housing in five sizes, from 14 to 25 inches (355mm to 635mm). The fans deliver up to six inches of static pressure and maximum capacity of 8,900 cfm. With their external rotor motors, the fans are 100 percent speed controllable.

The fans are available with extended-life, low-temperature brushless DC motors that are controlled by maintenance-free electronic circuitry. Because of reduced mechanical content, electronically commutated (EC) Rosenberg fan motors run cooler and quieter.

Rosenberg backward curved fans are available to meet customer-defined specifications including airflow, power, rotational speeds, noise level, overall dimensions and finish.
