SineWave Guardian™ is the best-in-class filter that delivers unequaled performance in cleaning the PWM waveforms generated by VFDs. It virtually eliminates high frequency content and voltage peaks, thereby reducing motor heating to give you extended motor life – and less downtime. The SineWave Guardian also offers incredible reliability and durability. It is more efficient and tolerates higher ambient temperatures making it ideal for a variety of applications from steel mills to oil fields. Its modular design and smaller footprint make it easier to integrate and install. It all adds up to the best SineWave filter and the best value on the market today.
Increase motor life
