DDI Guillotine Seals

  • DDI guillotine seals have unequalled durability, ease of replacement, and continued sealing efficiency.

  • The DDI sealing system requires substantially less seal air than competing systems.

  • All DDI guillotine seals are alloy C-276

  • Typical scrubber users have better than 5 years life on each seal component.

  • DDI seals automatically point in the direction the blade is moving.

  • Two way flexibility allows objects twice the size of the blade thickness to pass through the seal without damaging it.

  • Both inner and outer seals are pressure loaded when the blade is withdrawn minimizing seal air consumption.

  • Multiple progressive widths of seal material provide mechanical support for the sealing leaves while maintaining adequate flexibility.

  • Seals can be replaced internally as pre-assembled cartridges.

  • Seal maintenance does not require access to the external damper frame.
