The San Ace 40WF series 9WF type Oil Proof DC Fan is suitable for operating in high concentrations of oil-mist environments. These fans maintain stable operation and suitable for use in servo systems and industrial equipment. The 9WF type series DC fans provides efficient cooling for devices with high quality and high reliability, overheating protection function. If the fan blades are restricted, an over-current occurs and leads to a rise in the fan coil temperature. This can result in reduced performance, damage or a fire. To prevent this from occurring, SANYO DENKI's fans incorporate an overheating protection function. If the fan blades are restricted, the coil current is cut off at regular cycles to prevent overheating of the coil. When the hindrance is removed, the fan restarts automatically. Wiring fans with sensors or PWM speed control function, connecting positive and negative leads in reverse may damage the fans.
