Vi brator Effectiveness In Concrete

Round vibrator heads produce:

 
  • Better Consolidation
  • Greater Amplitude
  • Greater Velocity
  • Greater Influence

An independent research firm conducted a thorough study camparing the round vibrator head to other existing shapes available on the market today. The results provided, gave clear evidence that the Minnich round design offered greater amplitude, greater fluid pressure, and greater kinetic energy, resulting in a greater diameter of influence.*
