1. Safety knowledge
i. Product characteristic and usage
The air shower is a necessary channel for people or goods entering into the clean room in order to minimize the amount of particulate contaminants. Personnel move through the air shower while the particulate contaminants are blow off by the clean high air velocity. It be widely used in electronics, micro-electronics, precision instruments, laboratory equipments, food processing, beverage, aviation, pharmacy, optical electricity, semiconductor etc.
ii. Using in environment

2.6 After the light is on, if there is no operation in the stated time, the light will be off automatically.
7. Troubleshooting
|
Malfunction |
Reason |
Solution |
| Average velocity lower or higher than the rating. | 3 phase is connected wrong | Adjust 3 phase |
| If 3 phase is connected right, the air velocity is still low | 1. The pre-filter gather a lot of dust. 2. The HEPA filter is not working. | 1. Washing the pre-filter or change new one.
2. Change the new HEPA filter. |
| The fan is not working. | The connection of fan power has some problem. | Checking the connection of fan power. |
8. Maintenance
1) By the clean rate of environment, usually change pre-filter about 1-6 months and HEPA filter about 6-12 months.
2) Usually, supervisor should be checking the clean rate of clean zone by the particle counter in each two months. If the checking result isn’t noncoincidence with the required rate, please check it. (Leak or the HEPA filter is null). If the HEPA filter is not working, please change new one.
3) Please cut off the power supply when you change the pre-filter or HEPA filter.
