Choosing the right size
air storage tank. How much air storage you need can vary from task to task. In most cases a
10 gallon tank is adequate for filling/changing 1-2 tires at a time. Anything larger than 40 gallons is not recommended by
Voltair. See chart below to help you determine how much air storage you need.
Choosing a location for your air storage tank.
The great thing about air is that the inlet and outlet are one in the
same. It is possible to plumb 2 or three tanks together with minimal fittings and confusion (see diagram 8.4)
If you are mounting an air tank in an out of the way place then running your air hose from the compressor to your air stor-
age through the floor is the best way to go. This hose will be run through the middle hole of the 12-Voltair base.
Step 1
Mount tank. See chart to determine how much air storage you need
Step 2
Anytime an air storage tank is to be mounted on a mobile vehicle, Voltair recommends using a D.O.T.
(Department of Transportation) approved air storage tank.
(i.e.- brake tanks from semi trucks)
Step 3
Remove plug on bottom of manifold where the two quick couplers were screwed into
Step 4
Run hose from the bottom of the vehicle up through the middle hole of the 12-Voltair base and attach to
manifold where plug was removed.
Step 5
Connect the other end of the hose to the air storage tank.
