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.
With a rated frequency of 50 Hz, a rated speed of 1,350 RPM, an input current of 0.34 A, and a power consumption of 47 W, the PC48B2A420C is a 48mm-diameter ac cross flow fan that runs steadily at 230 VAC. It may satisfy a variety of ventilation needs that call for a broad, consistent airflow. Applications for this 48mm crossflow fan in the air curtain business are both common and specialized. It combines low noise with good energy efficiency, operating at a noise level as low as 36 dB(A) thanks to its aluminum alloy impeller and NMB ball bearing system. In order to provide a fast airflow air curtains at factory entrances, restaurant entrances, and shopping center entrances need to run for a long time. This helps to stop the mixing of cold air from inside and outside. The PC48B2A420C air curtain has a protection rating of IP44. This means it can handle dust well. It can operate in temperatures from -20°C to 70°C. So it is okay with humidity and temperature changes at entrances. The PC48B2A420C air curtain gives an airflow of 158.9 CFM. It also has a pressure of 25 Pa. This creates an air curtain. The noise level is as low as 36 dB(A). This is quiet. Does not disturb people. For built-in air curtain installations, this 230V crossflow cooling fan is the perfect OEM core component.
