help, people with UAS bags

first question...

my tank has four inlets
i can either do 2 compressors in, 1 pressure switch, 1 to valves from the tank
or
i can either do 1 compressor in, 1 pressure switch, 2 to valves from the tank.


which should i do?  is it better to run 2 compressors to its own inlet so i can get air in the tank quicker, or is it better to run the valves from the two inlets to improve air flow to the valves (i.e. run one line deticated for the front, run one line deticated for the rear)



question two:





one of my bags is mismatched

what troubles me more is... which one is the correct one?!  first one or second one?! i have three that looks like the second one and one that looks like the first one



this is a picture from UAS:

Its hard to tell from the pic that they are actually different.  Is the first one thinner?  If you can include messurements, you might get a better answer.  Also, those are some nice welds

i am referring to the chamber.  look inside. pic 1 has the circular metal piece on top, pic two has the circular metal piece on bottom (you cant see it)

I have the same thing on my bags.  As far as I can tell, it doesn't matter.  I haven't had any problems and I have been using them for over a year.

Also, you might want to give Zack a call at UAS.  He is real cool and is always quick to help his customers.

wait, so you mean your bags were flopped like how mine was?  i am going to install these babies soon but got to make sure before i do ettt

you can always T-off your inlet so you can run 1 compressor and the pressure switch into one port of your tank. lots of possiblities

The center pipe that your referring to when the bag is sitting in its relaxed state (no air) will be over to one side.  But when you put air in the bag it will move to the middle of the bag.

If your concerned about it, you can push the pipe over to the other side.
