Air Systems


Air Systems

With the acquisition of DMC, GSI began offering air systems in 1997. These systems move your grain through tubes using air, minimizing damage while maximizing efficiency and convenience. With an air system, you can change and maintain bins from the ground, avoiding air servicing. Here you can easily find the air system that will integrate seamlessly with your GSI dryer or expand your system just by laying more tube.
