Air vacuum pump

I am looking to start recovering my methanol. I have decided on using a vacuum with my Appleseed processor. Has anyone tried using an air vacuum pump (venturi type) with an air compressor. I found this model at Harbor Freight http://www.harborfreight.com/a...tm_source=googlebase . I already have an air compressor, and this model is cheap. I think it would reduce the worry of vapor getting into your pump as well, as it has no moving parts.

Having never done this I look forward to hearing from those that have on wether they think this will work.

Thanks in advance.

I like it...
No parts to be contaminated.
No motors.
No electricity.
No Sparks.

However.
It says the air consumption is 4.2 CFM @ 90 PSI.

That is a typical flow rate for a smaller vacuum pump.

I think you need specifics about the venturi to calculate the actual vacuum flow rate, but I'm guessing that it is very low (perhaps 1/10th, or about 0.42cfm at low vacuum pressures, even less at high vacuum).

Anyway, for $12.99, it is worth a try.

However, you may have issues if you have to evacuate large cavities.

I agree with Keelec , I might get one myself and
hook it up to the top of my centrifuge bowl. I got
a venturi from Mcmaster Carr for a methanol recovery
process. They do work !! Make sure you have a good dry air source.
You can make a pretty good air dryer out of PVC columns.
Good Luck
