EWO Electric High Frequency Internal Vibrators, which are directly connected with the mains supply at 230 V, 50/60 Hz, consist of a tractor unit called vibrator head, 10 metres of electric cable and of 5 metres internally reinforced operating hose. The high centrifugal force is generated by a high frequency electric motor integrated in the vibrator head.
Vibrators are equipped with a key pad (IP 66 protection) in polyamide, complete with switch protected by a reinforced gasket resistant to continuous use and wear. 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.
