12V Fans
QwikFlow 12VDC Fans are used in many applications where cooling is needed to remove heat from electronics driven products. 12V brushless fans are used in computers, medical Equipment, industrial equipment, electronic gaming, telecommunications, appliances and many other electronic applications.
QwikFlow 12V Fans have options that can control speed and noise though the change of voltage. This is a very effective way for engineers to design flexibility into a product. 12V Fans have a very high life expectancy because the DC motor runs cooler and at a much higher efficiency than AC Fans.
QwikFlow 12V fans can be manufactured with waterproofing and dust proofing using a international standard of IP ratings. The fan electronics and motor are dipped into a conformal coating solution prior to the final assembly of the fan unit. This would be important in industrial applications that are exposed to harsh environments.
QwikFlow 12v is a very common voltage used in electronic applications where DC voltage is used to power standard electronic devices. 12V Fans are used to draw away warm air from the circuit to prevent overheating and future failure of the electronic device.
QwikFlow 12VDC are available for many applications. These fans are available in sizes from 15mm to 254mm. These fans have safety approval from UL/CUL, TUV,CE and are manufactured to the highest standards.
