I hung the Delta AP200 air filter in my small shop this weekend. Very nice unit, but it is really noisy.
It makes two noises:
* a loud <whoosh> (of course, it's a 750 CFM air filter).
* a very piercing whine that even penetrates into the house.
No abnormal vibrations to suggest something came loose in shipment.
I'd like some comments and advice. Is this whine normal? Suggestions for noise reduction? And any suggestions on a 'speed control' to reduce the fan speed and a timer control are welcome.
TIA.
