The high-frequency internal vibrators of the IRFU range share one main characteristic: They simply connect to the 1-phase power supply and are ready to use. Quick, simple, flexible. Ideal for independent operation.

• Integrated frequency converter
• Reliable operation, even if the input voltages fluctuate and when used with generators
• Non-wearing converter due to sealed electronics
• Rubber coated head model designed for use with epoxy rebar.
• Available in different hose lengths and voltages
