I Just got AMAL's October Newsletter.
Good news if you are looking for a Pre Monobloc Float Chamber:
"AMAL's range of Pre Monobloc Float Chambers are available now. They come in a number of angles, control allignments, feed locations and connection types."
(Isn't " allignments " written with 1 "L"?..)
I thought that I have updated, and sorry if I forgot to:
Not so long ago I did actually get the filters from "Burlen".
I think that they changed it a bit:
The screw which secures the 2 halves together, seem longer than used to be,
and longer than needed (1.5 threads over the nut would be sufficient..)
And there is a lager "Nylock" nut, instead of the flat one.
Not very nice, but as long as it is here already...
Bill, may be one of these?..
