Description
The ebmpapst R2S133-AE17-43 is a compact 133mm AC centrifugal fan with backward-curved blades, designed for efficient air handling in various systems, often without the need for a separate scroll housing. Operating on a 230V AC (1-phase) power supply at both 50Hz and 60Hz, this fan draws approximately 0.24A (50Hz) or 0.21A (60Hz) of current, consuming 37W (50Hz) or 36W (60Hz) of power. It achieves rotational speeds of 2650 RPM (50Hz) and 2950 RPM (60Hz), delivering an airflow of up to 280 m³/h (164.8 CFM). Utilizing twin ball bearings for durability and an IP44 degree of protection, this model offers reliable and relatively quiet operation at 55 dB(A), making it suitable for applications such as air purifiers, ventilation units, and electronic cooling.
