Pack off heads

Pack-Off Systems are aimed specifically at providing levels of primary and secondary containment and protection during off-loading and material discharge.

Howorth’s pack-off heads are suitable for use with a wide range of drums, kegs, bags, boxes and intermediate bulk containers (IBCs).

  • Single point exhaust termination.
  • Mirror polish on all contact surfaces.
  • Easy membrane replacement.
  • cGMP design c/w fully welded construction.
  • Quick disconnect fittings.
  • Liner purging with Nitrogen.
  • Static or mobile support frames.
