Air compressor

At 35 degrees a big red compressor will usually finish the
6'th tire before it will cut out going from 20 to 40psi. From
my understanding it will do this quiker then most.

Go the Bushranger Maxair. It is nearly twice as fast as the ARB/Big Red/Blue Tongue ones. There was a good comparo about a year ago by Australian 4WD Monthly and the max air won hands down. And its slightly cheaper than most, about $350 when on special at 4WD shows.

Bushranger Maxair

I have the ARB compressor while my brother-in-law has the Bushranger Maxair and there is simply no comparison. Wish the Bushranger was around when I got my ARB one.

Yes agree go the MaxAir I have had a few different pumps and seen a lot of other pumps and its the best one I have seen around the $300-350 mark.
they have a five year warrenty but no parts available exept the filters for the intake.

Go with Max-air. Reinflated 6 tyres (incl CT) from about 20 to 40 before I could finish my stubby.

Or you could make your own using an A/C compressor- mine does 18 to 32 psi in 28 seconds.

the bushranger seems to be the fastest, but the Blue Tongue isn't far behind and is the only continously rated compressor around - expect to pay around $350

You want the best 12 volt compressor. Get a 'Blow Jax'. 3/4 horse power, 45 amp draw and puts out 6 cfm to 150 PSI. That's nearly twice as fast as your Bushranger. Available at specialist speed shops and normally used for air suspension. Over $600 I believe. Craig............................

The Bush Ranger sounds good. Most underbonnet areas on 4wd's are becoming more cluttered by the day & if professionally serviced the extra labour costs to dismantle this stuff not to mention the roadside fixes we need at times make the portable type seem the way for me!
