When sterilising the material placed inside them, industrial steam autoclaves destroy the microorganisms in the material, thereby ensuring perfect hygiene in the material treated.

In the first step of sterilisation, a vacuum is created inside the autoclave to open the containers and bags, eliminate the air and allow steam to enter all parts quickly.

In this process, the air passes through HEPA (biological-bacteriological) filters that retain possible contaminants and ensure that no microorganisms can escape to the outside.

The ATTSU KLAUS steam autoclaves used in hospitals and large research centres are equipped with this type of filter, since the material treated in this type of facility contains a high level of bacteriological contamination, and compliance with the maximum levels of diligence is essential.
