A fan in a film drying cabinet?  I think your asking dust to come a knocken!
I have a film/paper drying cabinet and have cut holes in the bottom and top of
cabinet and then attached furnuce filters over the holes- alows air and
moisture to pass through but not dust. A small heat unit in the bottom will
force hot air and humidity out the top.
