Feature: 1. Important Parameters: Voltage DC 12V, current 4.5A, rotation speed 6800RPM, air volume 51.9CFM, wind pressure 88.4 mmh2o, noise value up to 65.6dB. 2. Premium Material: PBT and glass fiber material make the fan blade not easy to deform, ensure the fan runs smoothly at high speed, high efficiency and energy saving. 3. Copper Coil: Pure copper wire greatly reduces the operating temperature of the motor and reduces the current, thereby improving the stability of the fan. 4. Heavy Duty Design: Maintenance free double ball bearings, with sufficient cooling air volume and air pressure, long service life. 5. Wide Application: Suitable for indoor and outdoor communication base stations, network routers, elevator ventilation, motor drives, control cabinet cooling, printers, factory automation equipment, etc. Specification: Item Type: Turbo blower fan Material: PBT, glass fiber, copper Size: Approx. 97x94x33mm/3.82x3.7x1.3in Bearing Type: Double Ball Current: 4.50A Rated Voltage: DC12V Speed Measurement: Support Number Of Revolutions: 6800RPM Interface: Four wire (supports PWM intelligent function, the main board automatically adjusts the speed) Air Volume: 51.9CFM Wind Pressure: 88.4 mmh2o Noise Value: Up to 65.6dB Wiring: Red positive, black negative Service Life: 10.0000 hours (25℃, 45～85% relative humidity environment) Uses: 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..
