Question Bauer P21 filter felt size

[sh_underwater]

Hello everyone.

It seems that three types of felt are used inside the P21 filter, but if anyone knows their size and thickness, please let me know.

I would like to know the size of the felt.

The Bauer plastic housing has a built in destruction mechanism. If you use it for a longer time it will break. We do not know what a "longer time" is. So it does not make sense at all to refill the cartridge. No refilling, no felt needed.

https://www.druckluft-service.de/index.php?seite=artikel&Artikelnummer=M333G030 I don't like this cartridge at all. It is very hard to get out the felts, poor construction.

There is (or was?) an Australian company producing a refillable cartridge for Bauer P21. I don't find the link anymore. The cartridges look very good.

This was not the one I was talking about but an option anyway. Unfortunately pics don't show very much of the cartridge.

I must have somehow managed to circumvent, the destruction mechanism
and I repack also rotate original Bauer filters with the greatest of successes

I also enter into the equation stainless repackables which don't last as long

I mainly pump to 300 bar, plus
all the compressors are electric

I've seen 2 broken Bauer P21 filters, they both were repacked. You do not realise a broken filter until you exchange it. How many times did you repack until now?

Why don't they last as long? Less volume?

That one is almost identical to the one I have been using for about 20 years. I get as many fills out of it as I did out of a Bauer cartidge.
