Laminar Air Flow/Clean Bench

As long as it's Laminar it shouldn't matter if it's vertical or horizontal. I use a vertical airflow one just like the one shown on this page: http://www.sentryair.com/specs/40in%20P ... 20Hood.htm

And it works great. I use active monitoring of the air quality and it's able to consistently maintain 0 particles measured. I generally run it on high for around five minutes or until the monitor has read zero for a while. Then I drop the speed down to medium so the airflow isn't so strong that it blows anything around.

My personal preference is for horizontal flow, because I find that most contamination comes into the chamber on the drives, especially from under the cover lid edges. These (and any particles on tools, hands, etc.) tend to fall down onto the top platter and my thought was that horizontal flow would help to clear these before hitting the top platter. As Jared said, it probably doesn't matter which you choose.

I agree with your thoughts about contaminants coming from the top cover. It's why I always open my drives upside down inside my down flow cabinet. That way the dust is forced down and hopefully doesn't get too much on the platters. However even if it does, it's nothing some good clean room swabs can't remove before you close it up.

Hello ,
I am planning to get a Air compressor the smallest i can get fix it in the office somewhere ,Then use plumbing pipe to take that air to three location ,2 of my cleanrooms and 1 to my hdd inspection area .I could blow away tough dust from under the lid using a air gun attached to this before starting the surgery .This will hall a lot ,Then i use swabs dipped in the magic liquid i have and clean the sides before i start ,These 3.5" drives are a mess with side dust .I also use a neat trick after i pack the hdd back so that all dust matrices left behind are gone to the back of the filter inside
