FOCUS ON EC FAN ONLY
PBM FOCUS ON EC FAN ONLY. Certificate: CE,UL,ROHS; Supply Ability: 100,000 pcs per year; MOQ: 1~100 pcs based on EXW price; 100 pcs above based on FOB price.
A high-performance air movement solution designed for demanding industrial settings is the PB3N500B4EM 500mm EC-AC backward curved centrifugal fan. Combining the efficiency of EC technology with the dependability of AC input, this adaptable industrial centrifugal fan produces remarkable airflow at 4708.00 CFM (8000 m³/h) with a comparatively low operating noise level of only 71 dB (A).
This centrifugal fan reduces energy consumption without sacrificing static pressure capabilities thanks to its precisely built reverse curve impeller design, which maximizes aerodynamic efficiency. The unit can be integrated into current industrial control systems because it runs at a Rated Speed of 1100 RPM and a Rated Voltage of 380 VAC. The robust 500mm diameter construction ensures durability in continuous-duty applications, such as HVAC systems and industrial ventilation operations.For applications requiring dependable centrifugal fans and blowers, this type offers the perfect combination of high-volume airflow, energy economy, and acoustic performance. The PB3N500B4EM offers dependable, constant performance backed by state-of-the-art motor technology and robust mechanical construction, whether it is utilized for factory ventilation, commercial air handling systems, or agricultural operations.
