ECOFIT-brand flange-mounted backward curved impellers provide optimal airflow and substantially lower installed cost for OEM customers, guarantees Rosenberg in a press release. These impellers are ideal for clean rooms (fan/filter units), fume hoods for factories, ventilation hoods for commercial kitchens and in HVAC systems. Rosenberg will be showing the ECOFIT impellers at AHR Expo, which will take place in Dallas (USA) from the 29th to the 31st of January.
 The impellers are attached to a unique flange with a built-in air inlet. The flange allows the fan to be installed quickly and securely with just four screws, cutting installation time from minutes to seconds and eliminating unnecessary parts and materials.
Another benefit is performance. The built-in inlet is perfectly sized to the impeller and factory installed to prevent airflow loss. This ensures the best possible airflow in any application.
At 60 Hz, airflows range from 255 up to 942 CFM and the maximum static pressures from 1.20 up to 3.2 of water, in temperatures ranging from -4 to +158°F.
Available in nine UL-listed models, standard features include IP44 protection, UL94 V–O polyamide or galvanized steel impellers, G2.5 balancing, Class F winding and thermal protection. Finger-guards are built in as an option.
ECOFIT-brand fans are manufactured by Rosenberg. The Rosenberg family of companies employs more than 900 workers in Germany, France and the United States. |
