DetailsThis system uses filtered air to add oxygen to your wort. It is an inexpensive, easy, efficient, sanitary way to achieve wort oxygen levels of up to 8 ppm. The aeration system uses an aquarium pump to force air through an in-line HEPA filter and then through a stainless steel diffusion stone into your wort. This system will never run out of oxygen; however you do need to let the system run for 20-60 minutes to achieve oxygen saturation. Make sure to check on the progress occasionally as it can create a lot of foam.
Note: The filter should never get wet, so don't try and sanitize it by dunking it in sanitizer. To store the filter, use a little tinfoil on the "In" of the filter and store in a zip-lock bag.

3.4 / 5.017 ReviewsAeration kit review.The aeration stone worked well if used with a tire inflation compressor at about 10 psi but the pump that came with the kit only had enough pressure to cause one or two bubbles per second. The pump is only rated for a small fraction of one psi.April 27, 2017Purchased
over 2 years agoFebruary 29, 2016Very quick and easy setVery quick and easy set up, got the job doneFebruary 23, 2016Easy AerationI purchased this to assist in the aeration of the wort. It is easy to use and continues to work for multiple batches of beer. I would recommend this product for low to mid alcohol beer production!March 30, 2014OKIt will pump air into your wort, but the psi is lacking so it takes a while. I just picked up the set-up that uses an O2 bottle from the hardware store, and it's much better. Spend the extra cash and get better results. 20-30 mins with the aquarium pump, or 1 min with the O2 bottle.January 20, 2014just okI aerated my wort with this system for my first two years brewing. It worked ok. It causes a lot of foam to form and takes about 15 minutes. The fermentations were ok. Then I decided to get the oxygen kit. My fermentations happened faster and were more vigorous. I only had to turn on the oxygen for about 30-60 seconds. Also, for higher gravity beers this aquarium pump system will not put enough oxygen into the wort no matter how long you use it. Only the oxygen system can do that. This product is a fine quality and all, but I would spend $20 bucks more and oxygenate instead of aerate. More bang for your buck.July 31, 2013aeration systemDon't bother with this, save your money. It takes 1/2 hour to add just a little oxygen. Pour your wort back and forth between 2 buckets and it does the same thing in 2 minutes for free!April 3, 2013It works but it isn't perfectMine was different than the picture shows but I think the functionality is the same. Just be aware that this stock photo may not be exactly what you get._x000D_Mine worked great for my first 3 5 gallon fermenters(I do 20gal). By the 4th fermenter it basically wasn't bubbling much at all._x000D_I didn't ever touch the stainless 'stone' but I suspect that the hop oils are clogging it._x000D_You can buy aquarium stones off of ebay for less than a dollar. So, I'm just going to use those and throw them away after use._x000D__x000D_If I had to do it again, I would just pick up a cheap air pump on ebay, get a hepa filter and disposable stones. You can probably do that for half of the price. This pump is actually an aquarium pump and you will see them on ebay for a lot less. I assume that a large part of the price at homebrew shops is due to the stainless 'stone'.April 1, 2013It adds a lot of airJust give it some time to oxygenate your beer, it wont do it in just a minute. I use this and get good results, no stuck fermentations. To prevent the stone from getting blocked I rinse it in boiling water and star san and handle it with gloves.March 24, 2013not worth itI don't have this EXACT unit...mine is a little different, but pretty close. Yep, gotta let it run in your wort for nearly 2 hours . I didn't know that when I first bought it....needless to say I was really disappointed._x000D_Just pour back and forth between buckets a few times to aerate, it's faster AND cheaper.March 7, 2013

Browse 2 questions Browse 2 questions and 14 answersdo you use this after the wort has been chilled and is fermenting?BEST ANSWER: After the wort has chilled to 80-90 degrees and prior to pitching the yeast is when I do it for 15-30minutes and by the end of that time the wort should be at perfect yeast pitching temperature and is full of oxygen !What air flow rate/pressure is needed for this diffuser? I used an aquarium pump in my first run with this and it barely bubbled.Aeration SystemBEST ANSWER: I had the same problem. I tried a number of progressively more powerful aquarium pumps without success. In the end I used a compressor and dialed the output pressure way back. Trial and error in a bucket of water, somewhere around 10psi works for me. Had to buy accessories for the compressor (harbor freight, less than $10) and used some ingenuity to make the connections. Good luck.
