ValleyLab Force FX and FXc Electrosurgical Units

  • ValleyLab Force FX and FXc Electrosurgical Units

The Force FX is a Digital Electrosurgical Unit. The Force FXc is a High Power Digital Electrosurgical Unit. Both generators feature computer-controlled Instant Response Technology designed to ensure a consistent clinical effect through all tissue types. You can use handset or footswitch controls to activate the generator. Receptacles are marked to ensure the correct connection of accessories. Indicators alert you when the generator is activated. The Force FX™ allows you to adjust the activation tone volume and reset the mode and power settings used previously. The Force FX™ can be used in conjunction with the Valleylab Force GSU System and the Valleylab Electroshield Monitor. Refer to the manuals provided with these products for more information.


ValleyLab Force FX and FXc Electrosurgical Units Features

ValleyLab Force FX

ValleyLab Force FX and FXc Electrosurgical Units generators with computer-controlled Instant Response™ Technology are designed to ensure a consistent clinical effect through all tissue types.

ValleyLab Force FXc

  • Instant Response™ technology ensures that the power delivered remains virtually constant, regardless of the tissue type
  • Improved performance at lower power settings minimizes the risk of tissue damage and neuromuscular stimulation
  • Three internal microcontrollers reduce system reaction time and increase the system’s processing speed
  • Spray coagulation voltage of no more than 9000 volts peak-to-peak output for broad, but superficial coagulation with limited capacitive coupling
  • A Power Efficiency Rating (PER) of approximately 98 for accurate and consistent cut performance
