Default air powered stir plate

Anyone use one of these? Seems like a cheap alternative to a motor driven one, but not as cheap as a homemade one. Looks like it could be driven by a simple aquarium air pump right?

That is pretty cool, but I awold assume an air pump is louder than an electric fan.

It's exactly eighty-four cents cheaper than the very solid (if basic) stirplate available here and vouched for my myself and lots of other HBT'ers.

And, with Dan's you don't need one of these:

Yeah, but if you could hook it up to SWMBO then all that hot air might be useful.

Not a cheap alternative if you don't own an air compressor.

did not feel like making an acnt to get the price on it. I did however notice that it will only handle a 1l starter. Reading the specs they listed thought my aquarium pump will handle it but then u add $24 to the cost of that stirplate.

A lot of people already have aquarium pumps to aerate wort. But, yea that homemade electric one is probably a better bet.

What type of aquarium pump do you have which can produce the pressure and flow rate required to spin the stir plate?
Remember aquarium pumps are diaphragm pumps which produce pulsating out puts.

Unfortunately the supplier only lists the pressure and not the minimum flow rate required which is the missing link to compare any air pump.
