ATEM Ultra-Lightweight Aluminum Air Shaft
Features
The air shaft from ATEM (Italy) is manufactured using aluminum alloy extrusion, making the body extremely lightweight.
It generates strong torque through three or six independently controlled air tubes.
The shaft is compatible with various core materials, including not only paper cores but also metal and plastic cores.
Its continuous clamp bar structure makes it ideal for use as a rewind shaft in slitter machines.
In the event of air tube damage, the tubes can be quickly and easily replaced on-site, minimizing downtime.
