Delta 40x40mm FFB0412UHN-SM36 Axial Fan 12V 50,000RPM PWM Control and Speed Out

Heavy Duty DC High Flow BLDC Fan with Speed Monitor (Frequency Generator) and PWM speed Control input.

This small fan motor runs at around 50,000rpm and can move volumes of air at an amazing rate. It is so powerful that it generates enough thrust to lift itself in the air when powered. PWM control input allows you to digitally control its speed.

Notes:
1) This fan is used mainly as a cooling fan in computer servers - an application that demands zero failure with years in 24/7 operation. That says a lot about the reliability of this product.
2) This fan can be quite noisy because of its high RPM.
3) Data shown are actual measured data.
