Laminar Flow Clean Benches

[zebong]

Hi ,

Would like to see how is the most used "air"


Vertical or Horizontal

Please dont forget to vote

Regards.

I guess in order to "prefer" you have to try both for a while which I don't think many people tried

[lcoughey]

I prefer diagonal.

We use Vertical Flow Hoods inside a Class 100 rated enclosure which uses vertical air flow units. Best of both worlds!

There's probably a dozen laptop filters that got sucked into my horizontal Baker flow hood. I hate it when that happens...Anyone have that problem with a vertical unit?

[Doomer]

Hmm
I don't even have this with horizontal unit
I'm not really sure how it can be, air blows INSIDE the bench it doesn't have suck

Baker Edgegard units.

We have two 4' Baker Edgegard units and one smaller Baker (setup for 1.8" and 2.5" only) which are horizontal as well as a Terra Universal VLF. I know what you mean about the Baker units. They have slots along both sides and the front bottom which are intake. There is the normal intake with prefilter above or below the unit as well. I think the primary advantage of this is if you are working with volatile chemicals, soldering, or any situation in which there are vapors, smoke, etc. Because with this setup, you do NOT get the particles in your face or room ,etc. Rather the air flow is VERY smooth and laminar towards the EDGES of the unit, hence the name.

Yesterday I did a head swap on a 1.8" Samsung HS08XJF. The suction is such that the actuator latch (so very small and light) actually became sucked approximately 12 cm or so inside!
Usually, I wipe my work area with a presaturated cleanroom wiper and lay in in front of that area before I begin my work.

I do love my Terra Universal unit, and though I was skeptical of the downward pressure it excerts at maximum flow, I lower it before I work on any drives.


Lastly, I am using these inside of a larger class 100 room, so this is simply overkill.

But it's not clean bench
It's induced draft
It sucks dust inside working area

Here's the unit we have...it's inside a hardwall Class 100 room besides.

It sucks dust inside working area

Actually it prevents pockets of vacuum around the edges or dust from getting in which would contaminate the working area.
