<< Can I hook this up to one of those portable tanks? >>
If the pressure switch high setting on the compressor matches the maximum
pressure allowed for the tank, answer is yes. If you don't know, it's a gamble.
If you add a checkvalve where the air enters the tank, and an unloader to
empty the supply manifold of pressurized air when the unit cuts out, then
These items are needed to keep the pump from attempting to restart under
high load due to the otherwise high backpressure from the tank.
I built my own air compressor using a 3/4HP Campbell-Housfield tankless
compressor and a portable tank. Initially a 4gal tank, now a 10gal.
These tanks had 3/4NPT female fittings, so you can unscrew the existing
"head" (which contains a tire filler hose, O/P valve and guage), and install
a standard manifold. Re-install the "head" on the manifold (so you get the
tire filler hose, O/P valve and guage), and then install standard compressed
air M fittings (or whatever) on the other manifold ports. And the compressor
Initially, I did without a pressure switch and unloader.
[The compressor has a O/P valve, and so does the pre-existing tank
When I switched to 10gal, I installed a pressure switch and unloader.
The first manifold I built from standard copper plumbing pipe. The second
manifold was turned out of brass bar stock. I ended up making my own
one-way valve (so the unloader would work), because buying one was going
to set me back $45.
The unloader is part of the pressure switch.
Then, I built a two wheel cart to mount the whole thing on.
Yeah, I probably could have bought a brand new unit for less than I spent
on this. But I _really_ know how they work now, and had something
to do in metal shop.
Do realize that the output of a compressor is _hot_. You need to make
the compressor->tank plumbing out of metal, and _try_ to get some heat
sinking on it. Initially, I just used hose, but it'd heat up to the point
where the rubber would soften and it'd blow off the fittings.
