Nitrogen Blanketing of totes with agitators

[DiscoStu216]

I need to install a nigrogen blanketing system on a process using 10 stationary totes. 3 of these totes have agitation. Is there a mechanical or magnetic seal I can use to seal around the shaft? The unagitated totes are obviously not a problem, but I'm having trouble engineering around these shafts....

Here is one that we use on staionary and portable blenders for dry powders and plastics. I would give them a call to see if they have a seal to cover your situation.
