　　1. Fan voltage, current, speed: voltage comprises starting voltage, the rated voltage (DC fan voltage range 4.2V --- 48V; AC fan and EC fan voltage range 110V --- 220V); associated current and speed, may be according to customer requirements.

　　2. Fan wire: type, length, terminal models.

　　3. Fan plastic box: PBT material (white and black), PS material (transparent)

　　4. Make a special function fan: moisture, waterproof, dustproof, RD stall alarm, FG signal measured wave, PWM pulse width modulation cooling fan

　　5. Fan Bearing Type: Normal four categories: oil bearings, double ball bearings, single ball bearings, hydraulic bearings. Oil-bearing advantages: low price, low noise, low price, the disadvantage is short-lived (about 30,000 hours). Dual ball bearing long life advantages (over 50,000 hours), the drawback is the noise Shaopian big (as the technology matures, now more and more small ball of noise), the price is relatively high. The advantages and disadvantages between single ball bearing double ball bearings and oil bearing. Hydraulic bearing life a little longer than the oil-bearing, the manufacturing process is slightly more complicated. Of course, the quality and nature of these materials is also a relationship, use good material to reduce fan noise and longer life.
