Product Details

An efficient, sanitary and inexpensive way to aerate wort in the primary fermenter. The aquarium pump forces room air through the sanitiary, in-line HEPA filter which removes dirt and contaminants. Then the air is delivered to the wort through a stainless steel diffusion stone, which promotes rapid absorption into the wort. For best results, aerate your cooled wort for 20-30 minutes.

Hands and stress free aeration. It doesn't get much better then this.
I used the pump for the first time today, wow. I average about four five gallon batches a month and this thing is going to be a time saver. I was looking at gerry rigging a cheap drill with some sort of plastic bit (I hadn't completely read up on the diy sites) when I found this. Drop the stone in and walk away for 30 min. I am getting activity in my air lock after only three hours from pitching the yeast, that is a personal best. It runs very quiet, if you are using 5gal primary (bucket or carboy) this will foam up real good after about 30 min so keep an eye on it. I use 7.9 gal buckets for the primary and it was almost over flowing out the top at the end of the aeration. The price is right, nab this if you are ghetto (or worse not) aerating your wart

just ok
When I first opened the box, I was a little confused as to what I bought. I thought it would be a simple air pump where you hook up the hoses, stone and away you go. Nope. The air filter doesn't fit into the small hose. So I cut a piece of tube off the larger hose in order to fit the filter on. Then I just crammed the smaller hose into the larger hose I cut off. The little black air on/off valve.... where does that go? I ended up not using it. I agree.. the instructions are lacking. Its not a complicated system and you can eventually figure it out. But for 40 bucks, it should be easier to fit together. If I were to go back in time and do it again, I would by a cheap aqua pump off of craigslist or something, hoses at home depot, and just by the filter and stone from NB.

Worth the cost!!!
Worked as advertised. Simple to use. Better than just shaking to aereate

I had no assembly issues. I actually wonder if NB hasn't changed something. After reading previous posts, I was worried that I'd have trouble. Was easy peasy. Stone stayed at the bottom. My only issue was wanting to do what the instructions said and aerate for 30 minutes, but was impossible with foam gushing and refusing to settle. Instructions said wait for it to settle then keep going. Later I consulted with a NB guy and he said, "if the foams coming out, mission accomplished."

I read most of the reviews on this product and I found it to be very simple to assemble and use. It is well worth the money. Order and shipping was a snap and it arrived on time. Would defiantly recommend this product.

Great Investment
Over the last few years of brewing I've been trying to up my fermentation game. Next to my temp-controlled fermentation chamber, this aeration system has made one of the bigger improvements in my homebrew. And seeing as the price is very manageable, this has a huge bang-for-the-buck. My first batch after using this system as opposed to the ole "shake your carboy til you can't lift your arms anymore" I was amazed at the clean profile that my brew had, which I attribute to a better fermentation. Also, every batch I've made since I got this system has required a blowoff tube, which I used to only need for hefes. Unlike many other homebrew products, the improvements seen with this item are quite noticeable.As for some of the complaints;Yes, the smaller tube is quite difficult to fit onto the inline filter. I've also noticed two different barb sizes on inline filters, with one being slightly larger and VERY difficult to use with this hose. But a little patience and hot water work fine.

Simple way to improve your beer. I have brewed 6 or 7 batches (5 gallon) using this aeration system. I am seeing a longer period of vigorous fermentation and lower FG than batches brewed previously. I boil the stone for 15 minutes after each use- no problem. As with any new piece of equipment (stir plate, etc.), I suggest browsing youtube, forums, Palmer's book, before trying it out.

works great
this is a must to get the fermentation going strong. cheap and works great. I bought one of these some yeast nutrient and a yeast starter kit and am super happy with all of them. out of the two batches that i brewed so far they have started fermentation within 2 hours and both of them required a blow off tube!

Dont understand the complaints
This set-up works perfectly for me.Doesnt take a rocket scientist to put together the first time. Small hose into the pump and the in line filter, then larger hose from the filter to the diffusion stone.The diffusion stones dances around a tad bit, but that is to be expected. 2 batches so far, and I havent had it floating yet.Works great, and at $35 its a steal. Beats spending time at the local farm store trying to come up with a system.Well done Northen Brewer!

Heat the small tube
When it comes to fitting the small tube onto the filter all you need to do is run hot water from your tap over the end of the small tube long enough to make it more flexible and it slides right on. No cutting or hassles just went right on.

can this run on 230v/ 60 Hz?
L A on Feb 20, 2016
BEST ANSWER: No. This has to run on 120V /60 HZ. If you connected this to 220V, it would burn out the motor. The easier answer is that it will plug into a standard wall outlet in the US.
Does the in-line filter also need to be sanitized?
Brian T on Aug 18, 2017
BEST ANSWER: Short answer: No. While the air passes through it, the filter should never otherwise be exposed to any contamination. Beyond that, I don't think the filter would hold up to moisture; in fact, I've ruined one (in another application) by getting it wet. It should be sufficient to periodically replace the filter (available here and almost anywhere that sells aeration units), though I'm not sure that's even necessary so long as the filter permits a good flow.
Will this work with 220V mains power ? (I will replace the plug connector)
A C on Feb 13, 2016
BEST ANSWER: It is a basically a small aquarium air pump. 220v will not work.
My husband has the aquarium pump set up for aeration and he asked for a new stone for xmas. Not sure if I need the 2 micron or 0.5 micron. Thank you.
B T on Dec 13, 2015
BEST ANSWER: Hello Becca,

Thank you for choosing Northern Brewer! The aeration stone for that set up would be the 2 micron stone. I hope this helps, have a wonderful day!
Does this work with the .5 micron stone also?
Nate P on Jul 18, 2017
What is the optimal time for aeration? Can it be done in more than one session?
J C on Apr 13, 2016
BEST ANSWER: This system can require about 30 minutes to get to the recommended oxygen concentration. You can do it in sessions to make sure it does not foam over..so you can turn it off and let foam settle. Cheers!
Can this be supplied to Nepal
A M on Sep 21, 2015
BEST ANSWER: I am sorry. We are only able to ship to addresses in the United States. There are a few forwarding companies out there though

that provide you with a U.S. address and we can ship to that. From there

they will be responsible for the package and any necessary documents required for shipping it to you. An online search should give you some options

if that is something you would like to pursue.
