I run a Fujimoto CP31, a 12" wide, 3 tanks (1.85L per tank) with wash dry module. Mostly I use it for colur RA-4 printing, but have used it from time to time for b&w.
If for b&w: Pick a film strength fixer and a developer that is not too dilute, and then there is no need to slow the rollers down from the usual RA-4 45" per tank. Even with the heaters turned of, I find the pumps tend to drive the baths up to about 24C.
I wash longer than the minute of so the W/D does, so I disconnect it for b&w.
I have done FB b&w in mine; it involves pre-wetting and then sitcking the floppy paper to a RC carrier sheet; mine came from long expired EP/2 paper that I have washed the overcoat off, and fixed, and then washed to leave it as just a gelatine coated RC slab. You still need a second fix, and archival washing, but it soes speed up production; I had a cast photo that went out as 25 8x10's of the same image.
