Autopress (AP)
For absolutely gas-tight and safe filtration
The BHS Autopress (type AP) efficiently separates even difficult-to-filter suspensions in batch production. Its mode of operation resembles that of a filter press, but the Autopress works absolutely gas tight and fully automatic, including cake discharge. The filter can be integrated with a fully tight and self-contained process (also GMP-compatible), thus also meeting requirements regarding sterility, explosion prevention, workplace safety or validation with ease.
The filter cake can be processed further, including washing, extraction, pressing, blowing out and drying. The thinness of the cake and a complete filtration process without any residues facilitate high throughput rates. As an additional benefit, the filter cake has a low residual moisture content. The BHS Autopress washes the cake efficiently, ensuring a pure product free of cross-contamination.
For each BHS Autopress of type AP, the design and actual filter surface are determined for each project in order to deliver an optimal filter solution for customers and their applications.
