Microbiological Safety Cabins

In the working area where stainless steel construction, stainless steel body, and a working table made of 304 grade stainless steel are present, there is one enclosed system grounded socket and an ultraviolet lamp. The system includes two HEPA filters with 99.999% efficiency in capturing particles of 0.3 µm size, classified as H14 class, for both supply and exhaust air. These filters are protected by pre-filters. For testing these filters, there is a DOP test outlet for 100% concentration. The air velocity is measured at the supply air outlet using a sensor and can be monitored on a digital screen, and the air velocity can be adjusted to the desired level using a potentiometer.

Microbiological safety cabinets are divided into two groups: negative and positive pressure, or three classes: Class 1, Class 2, and Class 3.
