GAA-4 GilSonic AutoSiever® Replacement Fines Collector is a component of the GAA-2 GilSonic Autosiever® Stack Assembly and required for use with the GA-6 GilSonic Autosiever and other Sonic Sifters. The Fines Collector is made of latex. It seals the bottom of the sieve stack and collects materials passing the finest sieve. The collector's latex walls flex as a result of audio energy from the GA-6 and create a pulsing column of air. One GAA-4 unit is included with the GA-6 AutoSiever; it is also available as a replacement item.
