Biosafety Cabinet Class II A2 LBS2-A50

A Biosafety Cabinet Class II A2 LBS2-A50 is a ventilated laboratory workspace designed to protect users, samples, and the environment from biohazards. It works by maintaining a 70% recirculation and 30% exhaust airflow, filtering air through HEPA filters before re-entering the work zone or being released. The cabinet provides an ISO Class 5 clean air environment, minimizing contamination during sensitive lab procedures. It creates a protective barrier using inward airflow and filtered downward laminar air. Contaminated air is filtered before it is recirculated or exhausted. This makes it suitable for handling low to moderate risk biological agents. It is commonly used in microbiology, tissue culture, and pharmaceutical labs.

The airflow system uses vertical laminar flow combined with a front air barrier to protect the operator. Contaminated air is drawn away from the work zone and passes through ULPA filters that remove 99.99% of particles 0.3 microns or larger. The filtered air is then partly recirculated into the work area and partly exhausted outside or into the building’s HVAC system. This balance prevents harmful agents from escaping the cabinet while maintaining sterility inside. The top exhaust design directs contaminated air away from personnel and lab spaces. Continuous airflow monitoring ensures that protection remains consistent during operation.

This Biosafety Cabinet Class II A2 LBS2-A50 includes a front sash with safety locks to prevent accidental exposure and maintain proper airflow. It is equipped with audible and visual alarms that alert users if airflow falls below safe levels or if the sash is improperly positioned. The built-in UV germicidal lamp allows for effective decontamination of the interior between uses, reducing microbial buildup. Real-time pressure monitoring ensures the cabinet maintains a negative pressure environment to contain contaminants. The cabinet also features an energy-efficient blower motor designed for quiet and stable operation. Together, these features help maintain a safe working environment for both operators and samples.

The Biosafety Cabinet Class II A2 LBS2-A50 is equipped with both visual and audible alarms that notify operators of airflow disruptions, filter status, or improper sash position. These alarms help prevent unsafe operating conditions by prompting immediate corrective action. The control panel displays real-time data including airflow velocity and pressure readings for constant monitoring. If the airflow falls below safety thresholds, the system automatically alerts users to avoid exposure risks. Filter clogging or maintenance needs trigger specific warnings to ensure timely service. These features help maintain compliance with biosafety standards and ensure user safety.

Yes, the Biosafety Cabinet Class II A2 LBS2-A50 top exhaust design allows for easy integration with a laboratory’s HVAC system for efficient removal of exhaust air. This integration helps maintain negative pressure in the lab and prevents contamination spread. Proper installation ensures that exhausted air is safely discharged or filtered according to local regulations. The cabinet’s design supports connection to ductwork with minimal airflow disruption. This flexibility makes it suitable for new labs as well as retrofit projects. Coordination with HVAC professionals is recommended to optimize system performance.
