Rotary Feedthroughs ISO-KF / ISO-K

INFICON's huge variety of mechanical feedthroughs offers the right device for all demanding applications, no matter if it serves e.g. in coating application chambers or in your applied research project under laboratory conditions.

The available flange designs ISO-KF / ISO-K and CF corresponds to our fitting line. All feedthroughs are suited to work in vacuum systems with leak rates up to 1 x 10-9 mbarl/s. For UHV an all metal designed feedthrough is also available.

Benefits

  • For transmitting high torque
  • With FPM shaft seal and ball bearings
  • 2011/65/EU RoHS compliant
  • Rotary Feedthroughs ISO-KF / ISO-K
