Class I Safety cabinet with a front aperture through which the operator can carry out manipulations inside the cabinet which is constructed so that the worker is protected and the escape of airborne particulate contamination generated within the cabinet is controlled by means of an inward airflow through the working front aperture and filtration of the exhaust air.

The class I safety cabinet provides a wide performance envelope for the user from aerosol hazards and other particulate within the cabinets work area. All extract air is exhausted through hepa (high efficient particulate air) filtration generally to atmosphere.

Protection for the user is provided by means of an inflow air curtain whilst the sample material in the cabinet is protected from the dirty laboratory environment by a constant stream of hepa filtered air (airflow velocities inflow .0.4 m/s & downflow between 0.25 and 0.5 m/sec).

The class III microbiological safety cabinet (often wrongly referred to as a glove box) is a highly specializedproduct designed for the most hazardous work typically carried out in a containment level 3 or 4 facility. Like the class II safety cabinet this class of cabinet provides protection for both the user and product albeit both to a much higher degree.

Class III cabinet protection to the user is provided by means of barrier protection with the user working through gloves or gauntlets and protection to the material within the cabinet by means of the air being hepa filtered as such, unlike the class II msc open fronted cabinet the class II is almost immune to outside air influences.
