Besides the characteristics of filtering system, which are the same as the Filter Model Container, the Protected Filter Model Container is provided with a fixed covertop. The steam and air inlet occurs horizontally on the lid sides, through a tortuous run which prevents dust from depositing on the filter. The loopholes position does not allow pointed and sharp objects to get to the filter, damaging it and affecting the tightness and sterility of the load. The double lid avoids that condensate coming from the containers piled up on it, comes into contact with the filter which, getting wet, could lose its characteristics as microbial barrier.
