Key Features
Why choose AOUSTIN® table filter ?
Thanks to its streamlined design and extremely demanding manufacturing standards, the AOUSTIN® table filter is as reliable as it is rugged. AOUSTIN® vacuum table filters are engineered and constructed to meet our uptime guarantee. Engineered with few moving parts, the filters boast a high rotation speed and a short filtration cycle resulting in a high quality finished product, maximised throughput and no product dilution. HASLER Group has specialised expertise in the fabrication of large-scale precision equipment. This expertise can be seen with the tight tolerances in which we achieve table flatness (+ / - 3 mm), even for table diameters up to 21 meters (69 feet). These tight tolerances enable the table filter to deliver unparalleled performance and lasting durability.
