Principle and configuration of mobile clean sampling vehicle

The working principle of the mobile clean sampling vehicle is to collect samples and maintain their purity through high-efficiency filtration and clean technology. It uses a centrifugal fan system to inhale air and outputs it through a high-efficiency filter and a flow-equalizing membrane, and transports the purified Class 100 clean flow to the item storage cabin, thereby purifying and protecting drugs and samples. At the same time, the hundred-level airflow and isolation protection facilities such as glass doors work together to form a positive pressure difference between the storage compartment and the outside, preventing the external air from contaminating the items in the storage compartment when the sampling vehicle passes through the low-level area. It is also equipped with an uninterruptible power supply, which can be moved freely without plugging in wires for easy sampling. Zhongjing Purification, which has mature production technology and rich manufacturing experience for clean sampling vehicles, provides the following configurations of clean sampling vehicles for everyone to better understand the clean sampling vehicle:

1. Equipped with an aluminum frame HEPA high-efficiency filter, its filtration efficiency is 99.99% @ 0.3μm, which can ensure that the static 100-level purification federal 209E standard is met;

2. The storage compartment has tempered glass windows on three sides and a tempered glass door on the front side. The vertical airflow creates a positive pressure difference between the storage compartment and the outside, which can effectively prevent the entry of external polluted airflow;

3. Equipped with a high-capacity UPS uninterruptible power supply, the battery can work continuously for about 4 hours when fully charged, realizing the wireless nation of the car;

4. Equipped with a large air volume and low-noise fan. The noise is controlled below 65db, and the wind speed is guaranteed to reach above 0.45m/s to ensure the normal operation of the entire system;

5. The pointer pressure differential gauge is configured to clearly indicate the pressure difference between the upper and lower wind ends of the high-efficiency filter, and timely remind to replace the filter;

6. The air volume adjustment function is configured, and the wind speed can be adjusted in three gears: high, medium, and low. The air volume can still be guaranteed to remain unchanged under the condition of the final resistance of the high-efficiency filter;

7. The PAO test port is configured to verify the installation integrity of the high-efficiency filter to meet the requirements of GMP specifications;

8. The sampling vehicle is light and convenient when moving, and can effectively buffer vibration. When loading or taking out items, you can lightly step on the caster brake pad to fix the position;

9. The push-pull handrail is configured to save effort and convenience when moving;

10. The whole is made of stainless steel plate to improve the durability of the product, beautiful and easy to clean.

In addition to the above main configurations, the mobile clean sampling vehicle can also be equipped with other auxiliary equipment according to actual needs, such as temperature and humidity monitors, gas analyzers, etc., to provide more comprehensive sampling data and analysis results. The principle of the mobile clean sampling vehicle produced by Bailun Purification is based on strict environmental control and sampling technology. By maintaining high cleanliness and an accurate sampling process, the quality and reliability of the sampled samples are ensured. It is widely used in environmental monitoring, pollutant tracing field experiments, etc., providing important technical support for environmental protection and ecological research.
