Kemo has been manufacturing filters and filter systems since 1965. We have tens of thousands of systems installed and in use, some of them more than 20 years old, and still functioning. ( How old is the PC you are viewing this page on? )

So far the oldest working Kemo filter system we know of was made in June 1971.
We try to support as many of the older products as we can, however technology moves on. Kemo electronic filter systems use components that were the best available when they were made, however after more than 10 years in use some of these age and change their performance. Some of the parts are no longer available, or at very high prices. We are not practiced in adjusting and setting up systems we no longer make, and they may not have interfaces which we can connect to our Automatic Test Equipment (ATE).

We will always try to support older systems, however it is not always a simple job, and we would not usually offer to calibrate older systems, but rather provide a functional check which shows that the filter is working.

If you have any questions please contact us.
