What kind of exhaust fans, and how many?

You could look into designing a fume hood with it, if you haven't already got one, for light use . . .just be very careful with the amounts of
flammable vapours you release inside it if the fan is inline with the motor/other electronics, unless they are sealed or separated . . .which, from my
experience with kitchen fans, often are sadly not.

I have to second what Hex says. I once was using an inline duct fan to move vapors from a M.E.K. distillation and the fan caused a flash fire. Scary.

Is there a way you could re-purpose the inlet for the negative pressure of the fans to create a simple vacuum pump for inorganic work (e.g. work not
involving particularly flammable chemicals or solvents?)
You will need to shift the grease filters and whatnot off them and have a look at the inndards to observe their construction, else find technical
documents on the internet for your particular models.
