Hi Jim:

The compressor may be out of production, but the filter element may not.

I don't know the HP or the discharge line size, nor do I know the element micron size.

I'm going to assume that it's a standard 40 micron or so, which is normal for a general purpose filter.

What is the line size?

If you can't find a replacement element for your filter, it will probably be OK to visit your local hardware store (better if it was a local fluid power distributor) and ask them for a general purpose filter that is the same pipe size as yours. Maybe it's a 1/4 NPT, maybe 3/8...could even be a 1/2". I can't tell you without seeing it.

Here is information on NPT sizing, and here is much for information about compressed air filters.

Hope this helps,

Cheers,

Bill
