Single or Three -phase dual power passive harmonics filters. 

Pro.Fi Filter will reduce by 50% the harmonics of the network while it will make indirect voltage stabilization by reducing instant overvoltage fluctuations. 

We proudly produce our filters in Greece since 2000 and are safe to state that we are the best provider for harmonics filters. Please note that a harmonics filter does not replace a voltage stabilizer but  is a necessary supplement to it. We are safe to say that the existence of harmonics in teh electrical power is a far bigger source of problems in equipment than a voltage stabilizer.
