Tools Pressure Tank and Air Compressor

Nov 15, 2011

    1. In less than a month I should have my pressure pot, if all goes well. I will be buying the 2.5 gallon paint tank from the local Harbor Freight. I have been researching and gathering as much information I can about the conversion that will need to be done. It seems there is more than one way to do it, so I will have to figure out which parts I will need after I get the pot.

      I am planning on housing the tank horizontally in a mount of sorts. I don't see many put this way, but I figure with a board inside I can better use the space in the 2.5g pot. Has anyone done this with theirs? Most pictures I have seen have the pots placed vertically...

      The part I am still deciding is what air compressor to get. From this one site, it says 2-3 HP is good. But then it also recommends a 6-10 gallon tank.

      I did find one air compressor that seems to be good. (Seeing as I don't know a whole lot about air compressors in general.) The one I am considering is: Makita MAC700 Big Bore 2.0 HP Air Compressor. But it only has a 2.6 gallon tank. Will this be a problem since my pressure pot is only 2.5 gallon in size?

      For those who have their own pressure pot, what kind of air compressor do you use? What size is the pressure pot used with that air compressor? Did you already have the air compressor or did you buy it specifically for your pressure pot?

    2. I already (well, my partner) already had an air compressor, it's 1.5 hp and my pots are 10 and 20 liters. It's not so much about the HP as the size of the tank, I think ~ not sure how big ours is but I can fill the 10 litre pot about 3 times to 60 psi before the tank has to fill up again. There is some info about conversions here: http://www.woodworkforums.com/f204/pressure-pot-76319/

      I would say that you should keep the regulator on the pot, and the safety valve, and just block up the outlet, cut off or unscrew the inside tube that sucks up paint, and add a ball valve to the air inlet so you can control the airflow and cut it off once you have the pot up to the desired pressure, and can disconnect the hose without having the air escape from the pot (until you open the ball valve).
