Air compressor for shox

i've got an iveco turbodaily coachbuilt motorhome, (posted on here before,
under the name of CampinGazz)
I've just got hold of some gabriel hijacker shockers, which are american air
shockers, standard shocker, with an air bag/bladder in a housing that
surrounds the top sliding part of the shocker,

Fitted them to the bacdk of my van as she was sitting a little low, and by
eck they make a differace, raised the rear end a bit, can only pump them
upto 130 psi at the mo.. more on that later, but the ride is a lot better,
go over a speed bump and the front end clunks over, the back end floats
over.. that's the best way to describe it,

I'll be fitting these shockers to the front as soon as i get the money for
another set.. luckily my van has the same mountings front and rear for the
shockers, as the hijackers are kinda universal,

Anyway, at the mo i'm pumping them up with my garage compressor, which puts
out 130 psi at about 8 CFM.. fine for running air tools, but not for air
shocks it seems, high-ish volume, low-ish pressure, i need the oposite for
air shockers,

I did scrounge one of those cheap 12 volt compressors sold by argos and the
likes for pumping up tyres, and took the system upto 140 psi.. but it took
about 3 minutes to shove an extra 10 psi in the shockers with the tiny pump
i had borrowed, says on the case it'll go upto 300 psi.. but when you can
only run these for 10 minutes at a time before they overheat, it'd take all
day to do that.

So i'm trying to find a suitable 12 volt compressor that'll work with my air
shocks.. once i have front and rear air shox on, i'll want to use them to
leavel the motorhome when camping by adjusting the pressures, so i want a
fairly fast system to pump the lowest shocker up to normal ride height when
i move off,

I know landrovers have air suspension systems on board.. well some do
anyways, and i imagine they use a 12 volt compressor and a tank?? anyone
know what pressure they run at?

and how fast is the system to pump up from say 30 to 200 psi.. i know weight
comes into it.. but some landies must weigh what my van does.. 3.2 tons,

Then the biggest Q.. if the air compressor set up is suitable from a
landie.. how much are they.. jsut the compressor for now, i'll add a tank
later, and my own solenoid valves for leveling,
i guess the compressor will be expensive to buy new.. anyone got a good one
second hand to sell me??

Many air-shocked vehicles have an engine mounted compressor, like the
A/C compressor. You CAN use an A/C compressor, but the lubrication of
the pump needs to be sealed. I did find a sitewhich detailed just which
pumps were OK. I'll have to see if I can find it.

10 bar, I think, 140psi.

there are some nice 12V tyre compressors called Truckair, which are much
more heavy duty and can be run continuously.

Is it just me, did I get a particularly bad one or am I just unlucky?
The Truckair I tested wasn't worth the effort. Apart from longer running
time (which can be achieved with most 'cheapy' compressors and a quid's
worth of 40mm fan) I didn't find them any better than the small ones ...
In fact I now use a Monroe badged one that came attached to a knacked
set of Monroe adjustable shocks - *much* faster and quieter than
anything else I've found apart from a double barrel foot pump and no.1
quadraceps.

I've not tried one, actually. I was going on the magazine reports and the
specifications. The Monroe one may well be a still-bigger/more powerful
pump - those monroe shocks are something like the ones the OP was on about -
they need pretty high pressures.

AIUI, the main selling point of the truckair is that it *is*
continuous-rated, most other not being so. The air pump is also supposed to
be bigger, which means that it'll inflate big tyres in less than half a day.
