Generally, the environments where waterproof fans are used are high temperature environments, but some customers have recently asked if there are some waterproof fans that can operate in low temperature environments. This is because some special products need to work at room temperature. In low temperature areas, waterproof fans It also needs to work, so, can the waterproof fan work at low temperature such as -20 degrees?

For customers who have such requirements, the manufacturer will design a fan that can work even at low temperature. Normally, if the fan with ordinary oil bearing is below -10 degrees, there may be no way to work, and the lubricating grease may solidify. 

Low temperature -20 degrees can still work normally, but the speed will be lower, and the lower the temperature, the bearing will freeze, freeze, and the shaft will not rotate. At this time, a short circuit will form inside the waterproof fan, the motor temperature will rise, and the temperature will rise. , the ice around the shaft core melts, and the waterproof fan can run.

The waterproof fan operates at low temperature. At present, there are many waterproof fan manufacturers that have not reached this technology, but as long as the customer has such requirements, the waterproof fan manufacturer can still find it through research.
