Important Note:
Rated Current: Rated Current shall be measured after 3 minutes of continuos rotation at rated voltage.
Rated Speed: Rated Speed shall be measured after 3 minutes of continuos rotation at rated voltage
Start Voltage: The voltage which is able to start the fan to operate by suddenly switching “ON”
Dropping test standard: Drop a minimum packing box in a height of 30 cm for perpendicular free falling motion to the surface of wooden plate of 10 cm. After test, connect the fan to the power, the fan still in normal operation.
Cross flow fans 40mm series, low noise and long life expectancy, are widely used in the computer information technology, network communications, as well as industrial production equipment, medical equipment, home appliances, etc .
