Science Lab Biological Safety Cabinet Class II A2 Biosafety
Cabinets ULPA Class II A2 Biosafety Cabinets
Class II A2 Biosafety Cabinets Advantage:
1. Small dimension,save space.
2. Centrifugal fan, speed, adjustable; H14 HEPA filter.
3. Large LCD display: Operators can check detailed status of the
cabinet, such as inflow and down flow velocity,
work area temperature and humidity, filter pressure, UV working
time and filter working time, filter life indicator etc.
4. Time reserve function: This can save 30 minutes waiting time
after activating the cabinet and the sterilization time after
experiment.
5. Remote control: Each function can be realized 6 meters away from
the cabinet by remote control,
which can protect the operator under emergency.
6. Motorized front window: The front window is motorized for
convenient, one-hand operation.
7. Voice prompt function: Airflow alarm, filter replacing alarm and
front window height alarm.

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.
