Enjoy harmonic mitigation, power factor correction, and imbalance compensation, all in one product. You can adjust the settings to your needs and put focus on the area that is important in your application.
Selective harmonic mitigation and automatic resonance detection ensure reliable operation tailored to your application requirements.
The Danfoss Advanced Active Filter AAF 007 is designed to reduce harmonic distortion of central or decentrally installed Danfoss drives. The newest-generation SiC switches give unmatched high efficiency with 60% lower power losses compared to similar filters and effective elimination of high-order harmonics. The filter is compatible with all drives in the Danfoss product portfolio, and is delivered pre-configured and tuned from factory, ready to use with the accompanying current transducers.

A range of applications for the water and wastewater, marine, oil and gas and mining industries.
Variable speed control with AC drives enables you to reduce energy consumption by running compressor applications at a lower speed.
Variable speed control of a chiller allows you to provide constant pressure regulation while matching the capacity to the actual need based on measurements in the system. Speed control is beneficial when a compressor runs for long periods at partial load. Reduce operational costs by running applications at a lower speed which reduces energy consumption. And reduce installation costs by optimizing the system and the compressor itself.
In the University Medical Centre (UMC) Ljubljana air conditioning system, Danfoss drives with integrated filters ensure low harmonic distortion, with maximum THDi of 5%.
VLT® HVAC Drives provide precise speed control of the thrust axial fans in Italy’s first vertical wind tunnel which offers a safe and fun sky-diving experience.
High efficiency and the necessary pressure required for the process to yield the best results are achieved by using VLT® AQUA Drives on all pumps in the plant.
VLT® high power AC drives strengthen this new cable-laying vessel’s tunnel thrusters, and active harmonic filters provide high-voltage quality for its 3.2 MW generator.
