Another possibility is to just buy a professional clean bench. It has the filters and blowers built in. I've seen them many times in Silicon Valley for $50 to $100. I threw away several of them when we closed down the Philips buildings in Sunnyvale. We couldn't even find a taker to haul them away for nothing. That was only 3 years ago. Last one I saw was at SV flea market. It was $50 and got no takers. That was about 20 months ago. Billy
