 | Biological Safety Cabinets Class I Cleanair™ Biological Safety Cabinet Class - I
Recommended for personnel & Environmental protection only.Air Balancing: Total exhaust cabinet with incineration
Class I Biological Safety Cabinet is defined as a totally enclosed, ventilated unit of airtight constructions. The front panel can be opened, allowing room air to enter the cabinet, sweep the inner surfaces, and exhaust-out through the duct. A front sash with glove ports may be installed. If glove are installed, air is drawn through a secondary opening equipped with a primary filter. A laboratory hood could be considered a class I BSC, the exhausted air is passed through HEPA filter before released in to the atmosphere. The Cabinet unit is maintained under negative pressure.

| Biological Safety Cabinet Class II Cleanair™ Bio Hazard Safety Cabinet - Class II
Recommended for Product, Personnel & Environmental protection
Class II Cabinets differ in the proportion of air re-circulated within the cabinet; velocity of airflow to the work zone; where the exhausted air is discharged. Air barrier at the work opening and the contaminated air plenum is under positive pressure. An air barrier between the operator and the work zone is maintained by a flow of room air into a full width grille in the work opening. The barrier air mixes with the laminar flow air in a sump underneath the work surface, and is exhausted to the outside environment through duct via a HEPA
