feed filter in diesel hydrotreater

[skvishwa]

In our diesel hydrotreator unit we are using automatic backwash filter for feed before it enters into the feed drum.from there it goes in to the reactor after heating.
this filter is supplied by Ronnigton peter which is of late showing more dp than before indicating that it has got some permanent clogging.
does anyone have any idea about the life of such filters?

I think the right name is Ronningen-Petter. Why not ask them directly ?
