Hello,
My company are installing some extractor fans into a series of luxury villas.
What we are experiencing is that some of the fan's installed are making a loud humming sound (bit like an aircraft engine) and not really performing very well, whilst others are perfect, good performance and silent as the grave.
The fans are two-speed and we have moved them all down to low-speed but still have this problem. Only things we can think of is that there is a problem with the louvres on some of the villas, or that the fan-blades may be spinning the wrong way somehow.
Was just hoping that someone out-there might have had a similar problem.
Thanks
