The structure of the Class II A2 Biosafety Cabinets:

Biological safety cabinets generally consist of two parts: a box and a bracket. The cabinet part mainly includes the following structures:

1.  Air Filtration System

The air filtration system is the most important system to ensure the performance of this equipment. It consists of a driving fan, an air duct, a circulating air filter and an external exhaust air filter. Its main function is to continuously bring clean air into the working room, so that the flow rate of the sinking airflow (vertical airflow) in the working area is not less than 0.3m/s, and ensuring the cleanliness of the working area reaches Class 100. At the same time, the external exhaust flow is also purified to prevent environmental pollution.

The core component of the system is a HEPA filter, which uses a special fire-resistant material as the frame. The frame is divided into grids with corrugated aluminum sheets, filled with emulsified glass fiber sub-fine particles, and its filtration efficiency can reach 99.99% to 100%. The pre-filter cover or pre-filter at the air inlet makes the air pre-filtered and purified before entering the HEPA filter, which can extend the service life of the HEPA filter.

2.  External exhaust air box system

The external exhaust air box system is composed of external exhaust air box shell, fan and exhaust duct.

3.  Sliding front window drive system

The sliding front window drive system consists of the front glass door, door motor, traction mechanism, drive shaft and limit switch, etc.

4.  The illuminating light source and ultraviolet light source are located inside the glass door to ensure a certain brightness in the working room and to sterilize the countertop and air in the working room.

5.  On the control panel, there are devices such as power supply, ultraviolet lamp, lighting lamp, fan switch, and control the movement of the front glass door. The main function is to set and display the system status.
