well, I was going over the designs for my server rack enclosure, and it occurred to me, how do i seal around bundles of wires passing in and out of the enclosure.
The ventilation system in my rack is negative pressure, and draws in through a filter. the enclosure is in my basement and there is a wood stove down there (ash dust), so the air coming in needs to be filtered. So what is the best way to non-permanently seal around the wires?
I was thinking of using just a tube, and pack shipping foam tight around the wires.
I was thinking of changing it to a positive pressure, negating the need to seal the wires, but the rack enclosure is mostly built, so it would be a major pain in the ass to change it now. D'oh.

Re: server rack enclosure :: how to seal wires to air leakage?!?!?
The best way is to identify a simple mechanical way minimize the amount of one space that needs to be blocked. Such as bundling like-sized wires together so they can be related the same. One useful technique is to use a flat clamp system using foam of rubber to clamp around the wires. YouTube idea would work, I would use a caulk to seal the wire bundles is it's tight enough.
So, how many wires, and sizes would be useful.a picture of the enclosure might be helpful too.

Fire stop or electrician's putty ("duct seal") will work, if you're reasonably certain you are done packing the pass-thru.
