ECFanGrid for new AHU installations.

Driven by our variable speed and energy efficient EC Motors, Rosenberg ECFanGrid delivers a compact solution. When we compare the space needed for the ECFanGrid to a single large blower our system can save you up to 50%. Our modular designs are flexible and whether it is a 1x3, 2x2, 2x3, 3x3 ECFanGrid we can tailor the system to your needs. Our multiple fan systems deliver uniform air distribution. This increases the efficiency of downstream components like coils and filters. Using multiple fan systems vs. a single blower results in higher frequency sound levels which allow for smaller attenuators.

Unobox – modular self-contained EC Fan

The Unobox is an assembly consisting of a backward impeller EC fan mounted inside a sturdy box. It is a Rosenberg’s approach to modular construction of a grid as a stand alone unit, or in a case when a previous casing no longer exists. Constructed out of an extruded aluminum frame with thermally and sound insulated galvanized steel panels. Powered by our energy efficient and easy to control EC motors. Can be stacked in the grid of any configuration. Simple and clean. Plug and Play.
