Bio safety Cabinets Class - ll is classified as

• Bio safety Cabinets Class - ll Type A1
• Bio safety Cabinets Class - ll Type A2
• Bio safety Cabinets Class - ll Type B1
• Bio safety Cabinets Class - ll Type B2

This Class II vertical laminar-flow biological cabinet is an open-front, ventilated cabinet.  This cabinet provides a HEPA filtered, recirculated mass airflow within the work space.  The exhaust air from the cabinet is also filtered by HEPA filters.   This type of bio safety cabinets provides excellent protection to users, products and the environment. While HEPA filters are effective for trapping particulates and infectious agents, these filters will not capture volatile chemicals or gases.

Bio safety cabinet class III is a totally closed compact and purely ventilated enclosure having an air tight construction.  All the experiments/procedures are performed through rubber gloves, which are provided at the front of the unit. The primary feature of class III bio safety cabinets is that they maintain negative pressure of 0.5” or more while in operation. The supplies of fresh air are taken inside the enclosure through specially designed high efficiency perfect air filters (HEPA). The exhausted air of the unit is passed through two modules of HEPA filters, which are strategically placed in series. The air passes through the two filters before being discharged in the environment. The exhaust fan for the Class III cabinet is generally separate from the exhaust fans of the facility’s ventilation system.  These types of bio safety cabinet have complete self sustained exhaust system.
