The Class II A2 Biological Safety Cabinet provides personnel, product and environmental protection for microbiological laboratory work. It features 70% air recirculation, 30% exhaust, dual ULPA filters, automatic airflow adjustment and a 7-inch LCD touch screen. Five cabinet widths are available to meet different workspace requirements.
This Class II Type A2 biological safety cabinet creates a controlled work environment for handling biological samples. Room air enters through the front opening to help protect the operator, while filtered vertical downflow protects samples from contamination. Approximately 70% of the air is recirculated and 30% is exhausted after filtration.
Two ULPA filters provide at least 99.9995% efficiency at 0.1-0.3 μm. The work area achieves ISO 14644-1 Class 4 cleanliness. An airflow sensor continuously monitors air velocity, while the automatic control system helps maintain stable airflow.
The 7-inch LCD touch screen displays airflow velocity, front-window status, temperature, filter life, UV-lamp life and system operating information. Audible and visual alarms warn of abnormal airflow, filter failure, UV-lamp failure or an unsafe front-window position.
Additional features include a motorized front window, foot-switch control, UV sterilization timer, safety interlocks, electric air-valve control, RS485 interface and power-failure memory. The removable 304 stainless-steel work surface and liquid-collection design support convenient cleaning and disinfection.
Available models have external widths from 1050 to 1800 mm, allowing laboratories to select a suitable working capacity. The series is CE certified.
