Business Name


EWO Electric High Frequency Concrete Vibrators are equipped with a small electronic frequency converter integrated into the power cable, suitable for connection to a single phase mains socket.

This line of vibrators is characterised by high centrifugal force, constant speed and increased wear resistance which makes it suitable even for the most consistent types of concrete and for continuous use.

The shaft is supported by four bearings for extra heavy-duty work requirements.

A small electronic converter, complete with switch, is integrated into the power cable.
The inverter is housed in a sturdy, dust-tight, waterproof (IP 66) aluminium casing. It is protected against overload, overvoltage, excess temperature and short circuits.

A led signals with different colours accurate functioning or the presence of a fault. Each colour corresponds to a specific fault.

All electronic components are covered with a resin so as to protect them from vibration, humidity and any shock.


Highly increased compacting capacity enables quick removal of air bubbles without any segregation of the elements composing the mass. The result is mechanically strong, durable and homogeneous concrete strength. The comprehensive range satisfies the requirements of both private and civil engineering sector.
