VLT® AHF 005 & AHF 010 Harmonic Filter

The Danfoss AHF 005 and AHF 010 are advanced harmonic filters not to be compared with traditional harmonic trap filters. The Danfoss harmonic filters have been specially designed to match the Danfoss frequency converters.

By connecting the Danfoss harmonic filters AHF 005 or AHF 010 in front of a Danfoss frequency converter the total harmonic current distortion generated back to the mains is reduced to 5% and 10% respectively.
