The image is a slightly different configuration but it gives you the same idea.


Helpful reading

You are correct. What happens is as the compressed air is pushed through the device it will create a vacuum in the carboy. It is the same idea as an old water bed draining method.

I hope this helps!

Well, my winegasgetter only cost $30, so no big deal.

Nice to know where to get a replacement venturi.

I used to compete with the inventor at local wine competitions, really nice guy and could make a heck of a wine.

I bought a single outlet version, made specifically for only degassing one carboy at a time. His big business is selling manifold versions that can degass 5, 10 or more carboys. Those are the expensive versions

After going to the Gas Getter site it looks like the prices are considerably higher than $30 now even for the basic model.

@daugenet -- I have a tank-less air compressor. It is heavy duty and will generate enough air pressure to fill car tires etc quickly. Should that work, or do I need a compressor with a tank?

@Red October: I assume that is a vacuum pump at the end of a racking operation? I picked up an old used vacuum pump from the discount pile at my LHBS for a few dollars. It is originally rated at 3 gal/min. I think I could probably rack my wine with it, but the suction doesn't seem to be very strong -- maybe the unit is defective -- hence the huge discount. I tried degassing with it today and it only drew a few small bubbles from a 1 gal glass jug of wine that should have gas in it.

I'd prefer not buying a new vacuum pump for $100 or more. I can rack my few carboys with a siphon as before, but I'd really like to find an economical way to degas by establishing a vacuum like the Gas Getter does. That is why I'm interested in daugenet's rig. I only need to know whether my tank-less air compressor will work.

thx,
feffer

That is an aspirator pump from hospital supply store, I have one similar to the one in the photo.

And yes, it was a bit over 100 bucks so out of line with your budget, but you should realize that it does make life a bit easier with racking and degassing, I even use it to bottle.

Set the rig up as illustrated, turn vacuum up to 20 and it will degas as it racks, after about 15-20 minutes you should be properly flat.

However, the "whip" does the same thing in 5 mins (the degassing anyway) so if your on a budget the drill/whip combo is the way to go.

Finally, if you're a patient person, you can leave it to bulk age at room temp and after a long while it will flatten out.
