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.
This 133mm dc backward curved centrifugal fan has a wide working temperature range of -25°C to 60°C, a high static pressure of 382 Pa, a huge air volume of 360 m³/h, low power consumption of 33.6W, IP44 protection, and a 24V DC power source. It is especially made for modern energy charging stations and outdoor DC-powered communication cabinets. The power supply for devices like 5G outdoor micro base stations, traffic signal control cabinets, and roadside units (RSUs) is usually 24V DC. The cabinets are dustproof, sealed, and have lengthy internal air ducts with high filter resistance. Regular DC fans do not have enough air pressure to go through the filters. With its 382 Pa high static pressure, the 133mm curved fans readily overcome the filter and convoluted air ducts, guaranteeing adequate cooling for vital parts like power amplifier modules and power supplies. Its 33.6W low power consumption and PWM speed control feature, along with a temperature sensor, enable on-demand operation and lower the total energy consumption of the cabinet. A 50,000-hour lifespan and stall prevention guarantee unattended dependability, while IP44 protection and a wide-temperature design adjust to outside rain, fog, heat, and cold.
