    Default AOF/AUF Blower size.

    I’m rebuilding my homemade evaporator this summer and am adding AOF/AUF. I’ve tried searching again and can’t find what size Koala blower people are using for a 2x6 evaporator. I thought it was a Koala 680 but was hoping to double check before buying. What size should I buy? Thanks.
    2012 3 1/2 gallons on a block arch. 25 buckets.
    2017 44 gallons on a Homemade 2x6 arch. 170 taps all on 3/16" tubing.
    2019 62 gallons on 200 taps on 3/16” tubing.

    University of Vermont, Proctor has a website that you can find papers written about various maple related topics. I believe that one of those papers is the one that you are looking for.

    Or look at mapleresearch.org.

    This will give you the answers https://mapleresearch.org/wp-content.../combeffic.pdf
    Once you find the recommended blower from Graingers, get the specs of that blower and compare it to the jump house blower. They are the right type of blower and are much lower cost, but you still want to get close to the same CFM. You may want the next larger blower, ($129?), still far below the grainger units.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.

    The Maple research org web site lists a specific Grainger model. Grangers description of that model list no CFM and no pressure specs. It also costs $421 without a motor. I know the Koala 680 will get me close, but I’d kinda like to more certain than just taking a stab at it. I know someone on here had some specific info about the Koala and proper sizing, but my search can’t find it again.

    I used to buy from Graingers quite often back 20-30 years ago when I was in the heating business. Back then once I had Grainger's number, I could go to that item and get all of the specs. I'll bet you still can. From the item listed in the https://mapleresearch.org/wp-content.../combeffic.pdf
    get the item number, then look it up on Graingers web site or in their catalog. All specs will be there.

    I’ve looked at both the Grainger and Dayton sites. They have a list of 30 specs that must include every size dimension for that blower, but neither site mentions cfm or output pressure. Guess I’ll try and call Dayton tomorrow.

    Well that was easy. Not! Four phone calls to four different Dayton Companies directed by four different recommendations and I never did get the Dayton Company that builds blowers. I ordered a Koala 680 1/2 hp blower because I think it’s the right size, but after many hours of work I still am not certain it is. Time to move on and do something else with my life.
