Thanks, but I do not have that much room on my bench. I have a shelf 18" above my bench that I lay tool on I want something low enough that I could put a second self above it.A cheap 20" box fan and a 20" x 20" furnance filter $25.00 investment will do just as well.
I have 2 in my work shop.
In my quest to find a blower fan I searched eBay and found a PSI dust collector version that needed two fans because they were broken and it was being sold as is. The original price was around $56.00 and was reduced to $46.00. So I started to search for two replacement fans. Called PSI and they wanted $30.00 each plus freight. So going back and forth trying to make up my mind I noticed "make an offer" button. So I offered $35.00 and it was accepted. In the mean time I saw fans that were exact matches the PSI DC for $20.60 each (on Amazon) and in one of the reviews the reviewer mention that this fan fit this Chinese made DC. So for $49.00 plus $35.00 plus freight I had a DC that I wanted for $105.00. The original price for the PSI DC is $199.00 plus freight. By the way in nearly all of the fan reviews buyers commented the fans made objectionable noise. What do they expect when you are buying a fan that is going 2600 rpm and moving air.
That is like saying the wind does not make noise at that speed or if I buy a TS that shows the on off switch clearly where I don't want it but I buy it anyway and say it is design flaw.
