High-frequency internal vibrators IRFU: Top Performance from every model

The IRFU high-frequency internal vibrator series are easy to use. They simply connect to the single-phase power supply and are ready to use. They offer reliable operation even when used with fluctuating generator input voltages. The Wacker Neuson IRFU high-performance internal vibrator is designed for long life and professional concrete consolidation results. It is available in many different versions. The integrated personal protection switch (Bodyguard™) offers a high standard of safety.

  • The Bodyguard offers safer operation even at voltages above the protective low voltage range. Therefore, the IRFU can also be operated using power sources that are not secured against fault current. This reduces the risk potential on the construction site.
  • The Bodyguard continually monitors the flow of current. In the event of a fault current, the power supply is interrupted within 3 milliseconds. This provides protection to the operator and the machine.
The vibratory head of the IRFU high frequency internal vibrator ist completely hardened.

Completely tempered vibrator head

  • The vibrator head is fully tempered. This makes the head particularly sturdy and prevents quick wear.

Thermal overload protection breaker

  • The IR series is equipped with a thermal protection switch. If the internal vibrator runs too long outside the concrete, it automatically switches off to prevent the motor from overheating. This increases the service life of the machine.
