The clean bench is a laminar flow device that operates as a closed console and cabinet with filtered air, typically used in cleanrooms. Anhui People and Purification noted that ultra-clean workbenches are widely applied in biomedical research, pharmaceuticals, space science, and other environments requiring high-quality air. These benches use high-efficiency filters to remove airborne particles, bacteria, and mold, ensuring accurate and reliable results for laboratory operations.

How to use the purification workbench:

1. Turn on the power

2. Turn on the fan 20 minutes before starting work

3. Activate the UV lamp for sterilization at least 30 minutes in advance

Hundred

Precautions for cleaning the workbench:

1. Before using a newly installed or long-term unused clean bench, clean it and the surrounding area with a vacuum cleaner or fiber-free tools

2. Avoid writing on the surface and minimize movement to prevent airflow disturbance

3. Do not store unnecessary items on the bench to maintain proper airflow

Purification workbench advantages and structure

The purification workbench offers convenience, efficiency, and comfort. It can be operated after being turned on for more than 10 minutes, making it ideal for long-term use in factory settings. The unit is driven by a three-phase motor (145-260W) and uses a special “super filter” made of microporous foam sheets to generate continuous sterile airflow. This "high-efficiency air" removes particles larger than 0.31 microns, such as dust, fungi, and bacterial spores. The airflow moves at 24–30 m/min, sufficient to prevent contamination from nearby air without interfering with alcohol lamp or Bunsen burner operations. However, during a power outage, materials exposed to unfiltered air may become contaminated. In such cases, operations should be completed quickly, and affected samples should be marked accordingly. If they are in a proliferation stage, they may need to be transferred later. For general materials, they might be discarded if necessary.

The purification station uses a three-phase four-wire system, with one line connected to the ground. The operating voltage is 380V. There is a specific order for the three-phase wiring. If the wiring is incorrect, the airflow direction may reverse, causing abnormal sounds. A simple fix involves swapping two wires. If only two phases are connected or one phase has poor contact, the machine will make unusual noises, and immediate power cut-off is necessary to prevent motor damage.
