I have heard different stories about variable frequency drive (VFD) for extractor fans. How do they work? Sellers I’ve researched about the drive claim it will reduce electricity costs. I suppose it will reduce noise as well. I have spoken to two suppliers of ducting. They both say that it causes an increased risk of fire as shavings tend to build up in the ducting. They also say that extraction fans are designed to run at one frequency and varying the frequency makes the fan very inefficient. Is this true? |

I'm very sorry that I posted the question in the wrong forum. After talking to an engineer at Danfoss now I have a better understanding. |
