1、 Hazards of long-term non cleaning and dust removal of equipment in the machine room 1.
The equipment is totally enclosed, without large-area exposed board and circuit board.
Leave no residue; 4、 Case 1 of live cleaning of machine room.
（1） .
Reduce power consumption during equipment operation and save operating expenses.
Reduce the indirect pollution of energy waste to the environment.
Taking the fan cooling equipment as an example, it is easy to deposit dust on the fan, resulting in the reduction of the cooling capacity of the fan, resulting in the continuous high load work of the fan for a long time, increasing the power consumption and causing waste.
