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
