What Is a Leaf Type Air Shaft Adapter?
A leaf type air shaft adapter is a pneumatic sleeve installed over a 3-inch air expanding shaft to allow it to handle 6-inch paper cores or plastic cores. Instead of purchasing a separate 6-inch air shaft, operators can use a lightweight adapter to achieve the same winding function more economically and efficiently.

Frequently Asked Questions

• What does a 3-inch to 6-inch air shaft adapter do? It allows a standard 3-inch air shaft to hold and operate 6-inch paper cores or plastic cores.
• Is the adapter lighter than a full 6-inch shaft? Yes. Air shaft adapters are significantly lighter and more economical than dedicated 6-inch shafts.
• What industries use pneumatic core adapters? Printing, slitting, packaging, film converting, coating and paper processing industries commonly use these adapters.
• What material is used? Typically manufactured from high-strength aluminum alloy with hard anodized surface treatment.
• Can the adapter size be customized? Yes. Customization of diameters, lengths and expansion structures is supported.
