First machine from our Big Haul on the healing bench! This us an Edwards E306A thermal evaporator. We are its third but really second owner - the previous folks just kept it in a corner gathering dust.

Its cooling circuit is leaking, it's missing a pump exhaust filter/conduit, and its film thickness monitor seems to have been violently ripped out at some point.

But the roughing pump runs and it seems to be pulling _a_ vacuum... So there's potential!

FAFO Updates 2d ago

Time for a FAFO Special: a 3D printed ISO KF to toilet roll adapter... also known as a DIY oil mist filter. At least temporarily. We should probably invest in some real filters that aren't a possible fire hazard.

(toilet roll filter idea by @spirit532, 'engineered' at FAFO, soon coming to a Printables near you..?)

(yes, we take out the inner cardboard)

@fafo A non-temporary option is to print a holder for 0.5µm polyester water sedimentation filter cartridges. One in the middle, fill the outside gap with activated charcoal and it works far better than even a lot of $200+ OEM units.
