Feature: 1. Characteristic: The rated voltage of the brushless centrifugal blower fan is DC 12V, the current is 3.8A, the speed is 7000RPM, with low noise. 2. Fan Blade Material: The fan blade is made of PBT and glass fiber material, which is not easy to deform, with strong wind and better mute effect. 3. Strong Shell: The shell is stamped with premium materials to ensure the stability of the fan at high speed, high efficiency and energy saving. 4. Stable Operation: The coil is made of pure copper wire, which reduces the operating temperature of the click and reduces the current, thereby improving the stability of the fan. 5. Dual Ball Bearing: Adopting maintenance free double ball bearings, the cooling fan has long service life, sufficient cooling air volume and air pressure. 6. Application: Suitable for indoor and outdoor communication base stations, data centers, network routers, control cabinets and network switches, elevator ventilation, etc. Specification: Item Type: Brushless Blower Fan Material: PBT, Glass Fiber, Copper Usage: Suitable for indoor and outdoor communication base stations, data centers, network routers, control cabinets and network switches, elevator ventilation, motor drives, control cabinet cooling (filter fans, heat exchangers, refrigeration equipment), printers, textile machinery, factory automation equipment, packing machine Size: Approx. 97x97x33mm / 3.82x3.82x1.3in Bearings: Double Ball Bearings Standard Voltage: DC12V Current: 3.80A Speed: 7000RPM Air Volume: 190CFM Power: 45.6W Noise: 65DB Continuous Operation Time: 180,000 Hours Fan Connector: 4 Pin Connector.
