When air is injected, numerous lugs (claws) protrude from inside the shaft, allowing it to clamp the core.

Features

• Tube replacement and cleaning can be easily repaired on-site.
• Tube replacement can be completed in 5 minutes if using a three-part lug system.
• As long as the core is within the lug length, there are no width restrictions, and it can be chucked at any position on the lug.
• It generates very little dust and can be used in Class 1000 cleanrooms.
  *We have confirmed that the amount of dust generated by the shaft itself, with a particle size of 0.5µm or larger, is 100 particles/ft³ or less.
