Single or Three-phase dual power Active and Passive harmonics filters. 

Pro.Fi Filter Active version  will reduce harmonics of 3rd - 51st class and adjust them below 5% THD

Pro.Fi Filter Passive version will reduce by 50% the 3rd class harmonics and by 70% the 5th, 7th, 8th harmonics of the network while it will absorb voltage spikes and instantaneous overvoltages and voltage drops. 

We have proudly produced our passive filters in Greece since 2000 and are safe to state that we are the best source for harmonics filters in Greece.

Note: 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 and voltage spikes in electrical installations is a bigger source of problems in equipment compared to the voltage fluctuation.
