Dave, the OB-050 wall mountable kit is supplied with the 230/3 pump.
I appreciate that there may not be much to be gained from a fuge in terms of glycerol/soap following the production of good quality water washed bio but I'm chasing the best fuel I can possibly make. I filter to 5 microns and a fuge is capable of sub 1 micron without the expense of replacement filters. The benefit being that should there be any residual glycerol/soap it will reduce these slightly too which is an added bonus.
