Mill Room Ventilation

[Buster]

Anybody have any suggestions or requirements for mill room ventilation? I have up to 10wx15dx14h space against an outside wall. How and how much do I need to properly ventilate this room? FYI, We are brewing into a 15 bbl brewhouse with plans for a 30bbl system in the future.
Thanks for any suggestions!

Much depends on your milling operation and how dusty your milling room environment is. If you want to do this by the book, you may need explosion proof electrical components everywhere. This is specified as NEMA 4X, Class II, Group G. You may also be required to have a blow-away roof or other inherently safe, quick pressure relieving device. This will be expensive. Some folks get around this by wet milling, which also has the potential to increase your yeilds. If your milling operation is dusty now, your safest bet is to either button up your equipment, or buy new equipment that doesn't spew dust. If there's no dust in the room, there's no need to ventilate. Remember that grain dust is not only potentially explosive, but can cause severe respiratory problems that can be deadly with chronic, long-term exposure. Good luck!
