It is important to keep the dust filter of the XRF clean. The XRF produces heat when it is active. When the filters are covered with dust it limits the airflow. This can lead to cooling problems of the machine.
Risk of shut down
When the needed airflow is too limited it can even lead to a shutdown of the whole system. You have to wait till the system has cooled downed completely before it can be operated again. This can take a very long time. Additionally, considerable dust may damage the electronical circuits within the device.
How often should the filters be cleaned?
Depending on lab the conditions the filters of the XRF should be cleaned every two weeks (dusty lab) or every month (clean lab).
How to clean the filters:
1. Carefully pull the dust filter cover towards the rear of the instrument.
2. Take the dust filters out.
3. Clean the dust filers with compressed air or with a vacuum cleaner (Do not wash!).
4. Check if there is dust collected underneath the dust filter. Clean with soft cloth.
5. Return the filters.
6. Place the dust filter cover back into the original position.
How to tell when a filter need to be replaced
Filters can be cleaned using compressed air or a vacuum cleaner. When a filter stays filthy it needs to be replaced. Filter 1 in the picture below needs to be replaced filter 2 is still reusable. Dust filters can be cleaned for a maximum of 3 times before they need to be replaced.
When a filter is completely covered with sandy dust it needs to be replaced immediately. It cannot be reused anymore. See the picture below for an example.
