Biological Safety

NSF 49 (Class II type A2): Biosafety Cabinetry – Design, Construction, Performance and Field Certification.

EN 12469 (Class II): Biotechnology – Performance criteria for microbiological safety cabinets.

  • Double-wall cabinet structures. Contaminated area surrounded with negative pressure to fully prevent leakage of contaminated air.
  • Innovative surrounded air intake grill design. All contaminated air in the work area is enclosed inside the cabinet. No safety dead end; the safety of personnel is never compromised.
  • The ECM brushless DC motor Best Energy efficiency.
  • Supply/Exhaust HEPA filter 99.99% efficiency @0.3 micron (Class H14)
  • Ergonomic 10 degree angle window design, reduces discomfort over long-term use of limbs and eye-strain.
  • 6mm anti-ultraviolet tempered glass.
  • 10 performance & safety tests before leaving the factory under strict quality control process.

Switch Panel

Window alarm

When the window is not at the operation height of 20 cm (8 inch), it will release an audible and visual alarm automatically.

Mute switch

When the alarm is activated, it can be muted temporarily while the alarm light continues to flash. If the abnormal situation has not been settled, the cabinet alarm will be activated again within a set time (5 minutes) to alert the user.

Safety interlock

When the window is opened, the blower and fluorescent light will be activated automatically and the UV light will be switched off. When the window is fully closed, the UV light will be re-activated automatically. The fan and fluorescent light will be switched off.

UV light timer

Built-in UV light timer for 0~99 minutes or hrs.

Full-Color Microprocessor Touch Screen​


user interface design. Easy to operate. Provides user with a better view of real-time operation status through the screen. Ideal to access various functions and parameter settings.

Automatic pre-purge

The pre-purge time can be set for the fan to run when the cabinet is warmed up. During pre-purge, the air is recycled in the cabinet to achieve uniform flow and steady status prior to performing operation.

Automatic post-purge

The post-purge time can be set for removing the residual contaminated air in the cabinet to ensure the cleanliness of the work area after use.


Built-in timer for counting up and down, electrical outlet, UV light.


Audible and visual text alarms will be activated when the following situations occur.
. Low inflow velocity.
. The window is not at the correct operation height.
. High HEPA filter pressure.
. Usage time of HEPA filter exceeds the setting hour.
. Usage time of UV lamp exceeds the setting hour.

Low fan speed mode

When the window is closed, the fan speed is automatically reduced to maintain work area cleanliness and save-energy.

Safety interlock

Safety interlock for window and UV light to protect the operator from UV irradiation. When the window is opened, the UV light turns off automatically. UV light only activates when the window is fully closed.

Operation record

Operation records can be viewed with a simple touch of the control panel.

Unit display

The unit display for air velocity and pressure can be set.

Language display

Multi-lingual display setting.

Fan control

Fan control setting allows the administrator to restrict the usage of cabinet by unauthorized personnel.


When the audible alarm is activated, it can be muted temporarily by touching the mute switch. If the abnormal situation has not been settled, the cabinet alarm will be activated again within a set time to alert the user.
