I know, I know; I'm supposed to put the fan down low and 'blow' the fumes out to reduce fire hazard, but it would be very difficult to completely seal the box and I don't want to blow H2 gas into the boat.
My question is, are brushless 12v computer fans considered 'ignition protected'?
If you blow the ventilation air through corrosion
and ignition protection wont be an issue. You will potentially vent corrosive / flammable products in the interior
. I wouldn't do that.
You could suck the fumes out. No issues with interior
venting. Your fan will be exposed to corrosive products and potentially some hydrogen.
But i must ask why do you need to vent your battery compartment using forced air? Seems like overkill for a house bank. Are you boiling the ocean down there.
Just having the vent tube, maybe an inlet and an outlet with a forced air scoop should be sufficient.
Our 675 Ahr 6 x 6V trojan house bank never causes any issues.
