Sunon MB Series Axial Fan, 12 V dc, DC Operation, 18.7m³/h, 1.26W, 105mA Max, 50 x 50 x 10mm

An axial fan is a device that creates airflow by using a motor to rotate blades housed within in a square or round frame. The rotating fan blades draw air into the fan and expel the flow in the same direction across a surface to cool it. Axial fans are a vital component ensuring the smooth operation of machinery and electronic equipment. Keeping equipment cool is Crucial as overheating can lead to serious complications including premature deterioration of parts, shorter life spans and sometimes, complete failure.

From Sunon, a range of DR (Dust-Resistant) MagLev DC axial fans providing a convenient cost effective solution for all your cooling requirements. The DR Maglev fans utilise magnetic levitating technology to produce a fan with superior performance, low noise and extended life. The Vapo bearing system and shaft never make contact during operation, resulting in zero friction whatever orientation the fan is mounted. In addition, the DR Maglev fans feature innovative Seal and Clip (S&C) and Blanked and Seamless (B&S) technologies. Further enhancing the axial fans dust resistance and oil leakage. DR Maglev axial fans also incorporate an automatic restart feature.

Blanked and Seamless technology or (B&S) is a technology that offers protection to the fan by preventing oil leakage. Retaining the lubricant is essential in keeping the Vapo bearing in full working order.

Seal and Clip technology or (S&C) is a technology that has been developed to strengthen the motors ability to prevent the ingress of dust. Prolonging motor life.

If the fan locks up while power is still supplied to the motor, an increase in coil temperature can occur. The automatic restart function can temporarily remove power to the motor preventing unwanted temperature rise. Once the locked fan rotor is released, the fan restarts

The Sunon MB series Maglev fan has a 4300rpm motor speed. It has a supply voltage rating of 12VDC and dimension of 50mm x 50mm x 10mm. It uses Maglev-powered technology, which enables fault-free use for a significant period. This ensures DC fans provide a flexible and dependable cooling solution for applications that require a fan to be mounted in any axial position. This fan has a power consumption rating of 1.26W. Sunon DR Maglev power series DC fans utilise Maglev technology to produce a fan with superior performance, low noise and long life. Maglev achieves this through zero friction, no contact between shaft and bearing. With excellent rotational stability, the Maglev fan eliminates vibration and typical wobble and shaking experienced in fan motors. Maglev also provides excellent high-temperature endurance that results in a long life. Additionally, Maglev fans also feature all-plastic manufacture of major items for optimal insulation resistance and electrostatic discharge (ESD) performance.
