Successor product: Danfoss Advanced Active Filter AAF 007
Mitigate harmonics, correct power factor, and compensate imbalance, all in one product. Equipped with the newest generation SiC switches, AAF 007 delivers more than 98.2% efficiency. This filter ensures 60% lower power losses compared to similar filters, and effectively eliminates high-order harmonics. AAF 007 is designed to reduce harmonic distortion for all Danfoss drives products.
Line voltage and filter current*
3 x 380–480 V AC ... 55 A modules. Maximum 440 A with 8 modules mounted in parallel
*Other voltage ranges and filter currents are available on request.

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.
