Rosenberg USA: Impellers
August 10, 2005
The EcoFitÂ® flange-mounted backward-curved impellers can be used for HVAC systems and commercial kitchen ventilation hoods. The impellers are attached to a unique flange with a built-in air inlet, which allows the fan to be installed using four screws, the company states. At 60 Hz, airflow ranges from 255 to 942 cfm, and the maximum static pressures range from 1.2 to 3.2 inches of water column in temperatures ranging from -4 degrees to 158 degrees F. Features on the nine UL-listed models include G2.5 balancing, Class F winding, and UL94 V-O polyamide or galvanized steel impellers. Built-in finger guards are optional.
