How to Select the Right DLC Filter for Your VFD: By Drive Current & Power
Match the DLC filter's WF model to your drive's input current (A) and output power (kW): single-phase S series 10–35 A, three-phase T series 6–990 A, three-phase + neutral TN series 6–170 A.
The longest-lasting product is usually the one whose care routine matches the way you already live.
Before buying, look for clear instructions, repairable parts, and finishes that can be cleaned without specialty equipment.
