refrigerator type compressor
« on: January 13, 2011, 07:17:00 pm »
Anyone tried one of these compressors ? I would like to know your findings before i cannibalize a fridge. similar ones can be found in window ac's freezers etc. I see them as being whisper quiet, reliable and capable of high pressures. The ? is about volume.  thanks in advance

Hmm... interesting.  Could these be used to transfer oil?  For example from my 55 gallon drum to a 5 gallon bucket?  I am not concerned about speed, but how many gallons per minute would one pump?  Are they self priming?

Thanks for the info.

already tried that, no they dont work they just gring to a halt as the motor isnt powerful enoughto keep it going, although pump would do it.

i use an old hydraulic pump, does it with ease

    My 8th grade "Science" teacher (over 40 years ago) used a reefer compressor as both a compressor and as a vacuum pump.
 - Jr. High Science is merely Basic Physics = introduction to how things of this world work.
    A friend used one with a tank to power his airbrush.  I am about to replace a bad air compressor on a medium tank with one.
    I saw one mounted on a smallish tank (maybe 2' x 1') in a garage powering a forge type burner some guy was building in a YouTube video.  No follow-up video, though, so no idea if it kept-up with demand.
    Yes, Russ, they be super quiet and efficient, too.  Most run 40 minutes of every hour, and cost only about $5 per month.    Sadly however, they are designed to pump substance in a gaseous state, not liquids.
O, well.  Onward & upward.
Shalom!

What kind of pressure could one expect from one of these compressors?

I'll ask next time Jeff calls from "out there on the Big Road," though I think we spoke of roughly 100+ psi on his system.
Where ever it tops, it's a somewhat less than spirited trip, yet plenty volume & psi to run an airbrush.

Ahh yes, lots of people doing this on youtube.  I found this one interesting:

Would this provide enough air to run a siphon burner system I wonder?
