Does anyone know where I might be able to buy some thin black foam filter
material, to replace the stuiff that was used on my Teral computers?
These systems have a large fan that draws air into the computer, and
the intake air goes through this very thin filter, in order to capture
large particles such as lint.
After 22+ years, that foam is nothing more than dust.
I would need something almost 5 inches wide, that i could then trim to
the proper shape.

Many test equipment sellers/resellers also carry actual foam made for filters
but it's (of course) high end pricing. Hewlett Packard dealers/parts
distibutors carry it that I know of. I mainly use the foam mentioned in my
previous message.

Have you tried any kind of industrial supply places? The downside of them
would probably be the quantity they would want to sell you :^)

So if the purpose of the foam was to cpature the dust, what captured the
foam? (:

Upon the date 12:25 AM 4/11/99 +0100, Tony Duell said something like:
No. The flaming PSU resistors and active devices catch the rest as a result
of the fan being jammed and not cooling stuff :-)
Seriously, I've seen the result of that happening on some sort of
transmitter or test gear (I can't quite recall exactly from 20+ years ago.)
A gob of dust and paper chad which collected on a heat sink adjacent to the
PSU pass transistor after the cooling fan died a natural death (sleeve
bearings siezed) went to flames :(
So if the
purpose of the foam was to cpature the dust, what captured the
foam? (:
The rest of the machine?

Why not go down to your local hardware store and buy an a/c filter and trim
it to size? Some window mounted a/c units use a black thin black foam sheet
under the grating. This should work. Hope this helps.

I decided to try using the carbon pre-filter material for a honeywell
hepa air cleaner unit. The air flow is definitely reduced, so i'll have
to watch and see if the computer is overheating.
The original filter material was so thin, it was very easy to see through
it. If i could think of something thinner, or more pourous, that would
be best i suppose.

I like to use replacement air conditioning foam/filters. On my 11/34, I
use A/C foam for in-the-window air conditioners as the front filter, and I
use the pleated-style central A/C filter for the rack filter.

Go to an air conditioning supply wholesalers or appliance parts dealer
and buy a universal window air conditioner filter kit. It is a black
open cell foam sheet about 1/8 to 1/4 inch thick that is cut to shape
for old a/c units that the oem filter is not readly available. costs
about 6 to 8 dollars.

Hi,
I am going through my email and came across this. Here is an idea: go to
a pet supply store and get a fish tank filter refill, the kind that
looks like a waterfall, then cut it to size. This may be white instead
of black, I don't know if this will be a problem for you.
