cleanThe principle of a workbench is to filter indoor air through a pre filter in a specific space, then press it into a static pressure box by a small centrifugal fan, and finally filter it through a high-efficiency air filter for secondary filtration. The clean airflow blown out from the air outlet of the high-efficiency air filter has a certain and uniform cross-sectional wind speed, which can eliminate the original air in the work area, take away dust particles and biological particles, and form a sterile and highly clean working environment. In order to better utilizeClean workbenchTo do homework, we need toClean workbenchMaintenance and upkeep are essential, soHow should we maintain and upkeep the workbench specifically?

1According to actual usage, regularly remove and clean the primary filter, and the cleaning cycle is generally3-6 months. If not washed for a long time, dust accumulation will affect the insufficient air intake and reduce the cleaning effect.

2tightness This workbench adopts a structure where all positive pressure contaminated areas are surrounded by negative pressure areas.

3not only ... butBefore using formaldehyde fumigation to sterilize the workbench, to prevent formaldehyde leakage, the entire machine should be checked for sealing using the "soap bubble" method.

4regularMeasure the wind speed in the working area with an anemometer (usually once every two months). If it does not meet the technical parameters, adjust the power supply voltage of the fan.

5When the fan voltage is adjusted to maximumWhen the wind speed in the workspace still does not meet the technical requirements, the high-efficiency air supply filter must be replaced, and the high-efficiency exhaust filter must also be replaced when replacing the high-efficiency air supply filter. After replacement, use a dust particle counter to check if the sealing around the four edges is good. If there is any leakage, it needs to be sealed with sealant.

6The fan does not require special maintenanceBut it is recommended to conduct a regular inspection.
