1. When the fan of the clean table does not operate, there are two reasons for this phenomenon. One is that the fan itself has a problem. The control panel of the clean workbench is malfunctioning, resulting in no signal output. For clean workbench fan does not operate, the method to eliminate this problem is: 1, check and replace the fan. 2. Check and replace the control circuit board.

2, when the clean table operation switch is invalid (can not achieve on/off) the reason for this phenomenon shows that the clean work power supply is not connected, the line has applause. To solve the problem of invalid use of clean workbench operation switch, we can take two elimination methods, a good plug. Carefully check and replace the circuit board.

3. When the working voltage of the clean workbench has been modulated to the maximum, the wind speed is still very low. The reasons for this phenomenon include 1 too much dust in the pre-filter, 2. In order to solve the problem that the maximum voltage modulation of the clean workbench and the wind speed is still very low, the elimination method we can take is A to clean or replace the pre-filter B to replace the filter.
