Thread: Air dyer idea

  1. #1

    Default Air dyer idea

    A friend of mine was having problems with his sand blaster clogging up from moister. He had tried all kinds of thing to help, but nothing work or was a lot of trouble. So gets a drive shaft (5'long+/-) drills holes in the yoke ends (1 on each) and taps them for air line couplings. Then just lays it on the shop floor. No more problems.

    Since then other friends and myself have used the idea with no issues, One freind has a three buy garage with three employees,(a lot of air used) with no issues.

    Just thought I'd share the idea.

    What you are doing is cooling the air with the large surface area of the pipe.
    This is like a franzinator cooler but after the tank.

    yes, a lot like that. I don't know the "science" of it or even if the "laying on the shop floor" did anything. We have ours just laying behind tool boxes, pipe racks, ect. out of the way.



    Ps. also I dont know why his has to go to the middle of the pipe. We just do the ends.

    Just running the air through metal piping pulls the moisture out of the air.

    So long as there is sufficient time for it to condense on the vessel, this is why you need something larger than the diameter of your piping. It should also be in area of the shop where the air is cooler, like along a concrete floor. And of course it needs a drain that should be drained every time before and after you use the plasma.

    At some point in time it will fill up with moisture from condensation, It needs to be drained on a normal basis so not to rust thru the pipe or tube.

    I would be a more concerned about the thin driveshaft exploding after it rusts over time, especially with it sitting on the floor..

    I think another good idea is using one of those small mini refrigerators, drilling 2 holes through the sides of it, finding some cooper coils from old refrigerators, water coolers, or whatever that will fit inside, or get some copper tubing and coil it up and run it out the drilled holes, solder on some fittings and you have a little chiller unit on the cheap..

    I think that is a great idea. Can also double as a beer fridge. For those who don't want to have something using electricity all of the time, maybe you don't have to plug it in - just put some ice in there before you need to pull some air.

    Here I've been scratching my head over a DIY refrigerated dryer, and this is about as simple a solution as a guy could find. Brilliant brucer!

    One problem is that air to air intercoolers are not very efficient and need to be quite large. Refrigerated dryers usually circulate the refrigerant in direct contact with the air lines. You also need to employ a centrifugal condensate separator to get the moisture out of the chilled air.

    That was quite uncharacteristic of me to praise simplicity over efficiency wasn't it? Must have been the multi-purpose use for cooling beer that swayed me.

    Still, it seems like it would pull out more water than a driveshat laying along the shop wall if you put a bit of thought into the design.

    I solved the dry air problem no loud compressor just put an high pressure argon welding tank full of 99.9% dry air from a SCUBA dive shop it last about two half hours of cutting for $15.00 you would use more than that in hydro(electricity).
