Does AOF improve GPH or reduce the amount of wood you use?

[Swampmapleman]

Was just wondering if the boiling rate is increased by the gasification over the regular AUF? I know that AOF reduces the wood comsumption by up to 30% but I didnt know if the GPH increases if you already have AUF.

Yes it does hotter faster boil love mine would never go back.

Last year we added AOF and AUF and doubled our GPH.

How are u adding air over fire? I already have auf

add two 3x6" tubes down side of arch and buy a HP blower.

AOF does both. When I added mine my boil rate jumped about 20-25% and my wood consumption dropped to about 2/3.

Hotter, more wood, more syrup!

can you use the same blower and just elbow off from the plenum for aof, or do you need a second blower? also what size holes should be in the pipes and how many ? I am throwing around the idea of trying aof, and looking for ideas/advice.

My AOF and AUF both run off the same HP blower. You will need valves on each leg to get the right balance of air to each. Mine starts with a 4" supply line that splits into 2 lines, 3" each. Then each has a 3" ball valve. On the AUF the valve is only open about 25%, on the AOF the valve is open about 2/3. Once I got the balance where it seemed right, I have not changed them again. They have been that way for several years.
