if you're not handy, i wouldn't suggest trying to convert a $250 motor into a $50 air pump

eco-plus comm line ~the comm 1 is adequate for a 5 gal brewer & the 3 is pretty popular

Motor was free...... And I have 3 more in boxes in an old warehouse..... Oh well. Plus I'm looking to do a few hundred gallons at a time.....

I worked on this design for 1.5 years before I was satisfied. Our line of brewers directly injects air into the composted material.

No floating bag of compost dangling in the water with air bubbling from the bottom.

Our 55 gallon brewer will be available in Spring 2014, and it will be priced around $300. It is just a scaled up version of our smaller brewers. It has already been tested, but we still need to do some tweeks to make sure everything is good to go.

Tea brewers which blow air into the composted material have been around for a long time. For those wishing to use the extraction bag my 50 gallon design does that in addition to the airlift.

I advocate running air/diffuser into the extractor if using one in homemade AME (aerated microbial extrapolation) devices.

What is different about your design? Do you have some data to share?

I don't have any data prepared. I will be getting some media together for the 2014 growing season. We are still trying to get settled from the move to Denver, and it has me more than behind on projects. Worth it though! :)

Got this puppy working tryed to make it as clean as possible. Used an eco plus comm1 for the airpump mounted upside down under the lower platform. I Need to brace the legs with some T's and some piping. paint the plywood and glue up some of the fittings that are not made for a press fit.

Also changine the waterfall head from a 45° to a 90° to see if I can get more of a vortex effect

All in all it was prettt simple spent about 100 bucks on this and that including the pump

How are you guys taking care of leaks on the hand fit stuff? I have a couple spots that still drip after I tryed to clean up the ends and get them flat smooth. If I glue these spots together it will make it a little harder to clean

Paint4420 - I see a design flaw with your brewer. The air pump is always placed at least 6inches above the top of your brewer. If I understood you correctly, yours is mounted below your water level or your brewer. This ensures that if your pump goes out you wont have water all over your floor through your air pump.

As for your trouble fittings: I personally have just glued every other fitting. It's still easy to clean and you have now eliminated 50% of your potential leaks. The remaining fittings that might still leak, I have installed no-hub fitting. https://www.google.com/#q=No+hub+picture
Hope this helps.

Hmm never thought about the airpump letting watter out. If it were to fail. I accidentally let it fill with water when I first started it and I didnt see any drip out. Ill have to check out the design of the eco 1 and see if it does fail if it can let it out.

Edit. Looks like there is a diaphram that will block any liquids from escaping if the motor fails. However if the diaphragm were to disintegrate somehow I could see it happening. Either way ill have this girl in a tub or outside when its running to make sure if it is to overflow or I spill water or something happens that it is contained.

Organicbuds is right on this one.

If the pump fails, your entire brewer can empty onto your floor.

Kind of like when you are stealing, I mean borrowing gas from your neighbors car. :)

I think this should serve as another layer of protection

Unless of course there is a better option. I dont really want to remount the pump. Nor do I want a 1/4 inch tube in the airlift.

On second thought I could just rout the tubing up and over the water line and that would it in check if anything were to fail

Routing the tubing up and over, then back down would fix this problem, and you wouldn't have to remount. Good idea paint4420.

I think there is a potential for rust inside your air pumps diaphragm when you let water in that way also. Have you run a tea through your brewer yet? If not let us know how it works out for you.

Brewer works well ill try to get video. But its just like every other. Acheiving a nice vortex was done by the new 90° fitting and working WITH the coriolis effect haha love that stuff works one way but not they other.

Also to address the disign flaw ive added konger hose and an 1/4 " are valve

Mine seems to seal itself up with debris/slime after running for a few minutes.

Thanks to everyone for all their designs, mistakes, and chatter.

This was so much easier to make than i imagined it to be.
 
I took the route of drilling 1/16 in. holes, as I did not know where to get it cut at 250 micron such as Microbeman stated.

where does it say that MM suggests drilled 250 micron holes for the diffuser? also does anyone have any idea on the average bubble diameter that such holes would produce?
