**Common Troubleshooting Methods for Air Shower Rooms**
Air showers are essential in cleanroom environments to ensure that personnel and materials are free from contaminants. However, like any technical equipment, they may encounter issues. Below are common problems and their solutions.
**1. Power Issues**
First, check the power supply. An air shower typically has four main power sources:
- The outdoor shower box’s power switch.
- The control panel inside the indoor cabinet.
- The power switches on both sides of the air shower room (these prevent accidental power cuts during emergencies, enhancing staff safety).
- If the air shower is running but cannot be opened, the lock tongue may not be fully inserted into the lock hole.
If the power indicator isn’t working, don’t attempt to troubleshoot the power supply yourself—contact a professional. Also, if the door is locked or blowing continuously without stopping, it might be due to a program error. In such cases, turn off the main power and restart the system.
**2. Fan Reversal or Low Wind Speed**
If the fan is rotating backward or the wind speed is low, check the 380V three-phase wiring. Incorrect wiring can cause the fan to reverse or reduce airflow, potentially damaging the circuit board. It is strongly advised that users do not attempt to rewire the system themselves. Always consult the manufacturer for proper installation.
**3. Fan Not Working**
If the fan fails to operate, first check the emergency switch on the outdoor shower box. If it is tripped, press it and turn it to the right to reset it.
**4. No Air Blowing**
In addition to checking the above points, ensure the emergency stop button inside the air shower room is not pressed. If it is, pressing it again should restore normal operation.
**5. Automatic Sensing Failure**
If the air shower does not automatically sense when someone enters, check the light sensor located in the lower right corner of the indoor unit. Ensure it is correctly installed. If the sensor is misaligned, it may fail to detect movement, preventing the system from blowing.
**6. Reduced Wind Speed Over Time**
After prolonged use, wind speed may decrease. This could be due to clogged filters. Check both the pre-filter and high-efficiency filter. Replace them if necessary. Typically, the pre-filter should be replaced every 1–6 months, while the high-efficiency filter should be changed every 6–12 months.
