1. Main Classifications By Structure Axial Fan: Features large air volume and moderate air pressure, suitable for ventilation and heat dissipation Centrifugal Fan (Blower): Features high air pressure and small air volume, suitable for heat dissipation in narrow spaces and air ducts By Dimension 2510, 4010, 6015, 8025, 9225, 12025, 14025, etc. By Voltage 5V / 12V / 24V / 48V By Driving Mode Oil-impregnated Bearing Double Ball Bearing (Long service life, high temperature resistance) Hydraulic / Nano Bearing (Low noise and long service life) 2. Key Parameters Rotational Speed: The higher the rotational speed, the larger the air volume, and the higher the noise Air Volume (CFM): Air delivery volume per unit time Air Pressure: Capability to overcome air duct resistance Noise (dB (A)): Generally 20 ~ 45dB Service Life: The service life of ball bearing fans is usually 40,000 ~ 60,000 hours Wiring: 2-wire (power supply), 3-wire (speed measurement), 4-wire (PWM speed regulation)
