EWO – Internal vibrators with built-in converter

The EWO high frequency immersion vibrators are equipped with a small electronic frequency converter, integrated in the power cable. This makes them suitable for being connected directly to a single-phase power outlet (115 V, 230 V, 50/60 Hz).
The range of EWO concrete pokers is characterized by a high centrifugal force, constant speed and greater resistance to wear, which makes it suitable even for the most consistent types of concrete and for continuous use.
The shaft is supported by four bearings for working in harsh conditions.
