Compressor

deverall11 · Guru

Bought it at a Caravan & Camping Show some years ago. ARB. Main use was to inflate and deflate
airbags in the rear when the caravan was hitched.
Also to adjust tyre pressure once again based on whether towing or not.

Boss Air PX07 - used frequently to air up 4wd tyres & to supply an air blow gun. Used in conjunction with a 9 litre air tank. 100% duty cycle.

A simple, powerful reliable & effective compressor sold by a company who off a good backup service.

ARB same as above

Basher · Senior Member

We never travel without ours, as others have said, to inflate tyres if going bush or on bad corrigations after dropping tyre pressures down to suite the conditions.
Ours is a Bushranger about 12yrs old and still going.
Very handy when towing caravan on corrigated and rough roads, 8 x tyres inflated in about 15mins

Have 3 ARB compressors in parallel (90 amps) so all work is quicker.

Also have air tank, after cooler (can be refrigerated & now fan forced), moisture trap.

Last week helped a person replace tyre, to make life easier pumped up the flat tyre, it had a decent hole but the air was going in quicker than out, so the car was easier to jack up.

Have an ARB compressor with a big air-tank in back of car to provide enough pressure to help seal the bead when fitting tyres to rims. Cheers

We have a ryobi 18v one and it works well. I lower tyre pressures when on unsealed surfaces and reinflate them with it in a fairly short time .

Had one forever, single Cyl Blows up to 110lbs per.
98% of it's use. O.P's Tyres. It's a "feel gud thing".
Just in case hey.

TJM branded works well for me. If you do invest, be careful of hose join to compressor, it gets hot pretty quickly.

Whenarewethere · Guru

One test I read, the ARB compressor at the hose connection got to 130°C. Dangerous stuff & also melts plastic hoses. You could add a short section of stainless steel/rubber hose.

I added internal & external heat sinks & high volume computer fan. Only gets warn now.

The other benefit is the air is already cooler before it gets to after cooler & moisture trap so water in the air will condense more easily.

If compressing air by a factor of 7 (typical), you end up with 7 times the water.

If you are airing up & down regularly you end up with a lot of water in the tyres.

Adhere to the Duty Cycle of the compressor so you don't cook the compressor.

After cooler with fan forced cooling (they have grills now). Can also drop it in the fridge for condensing pretty much all water out of the air.

Just need a desiccant dryer before the last particle filter.

Dr Air Pro Flow mounted with retractable air hose........about min 30sec to pump up a 265/75/6 from around 23 psi

Whenarewethere · Guru

From 23psi to what PSI for about 30 seconds per tyre?

With 3 ARB compressors at 90amp at the upper end of compression, at 14.4 volts with engine running according to my Kyoritsu 2046 clamp meter, with a tyre of 70 litres volume is take 28 seconds to pump from 20psi to 35psi, including 4L air ank as a starting point (actually 3.68L as I measure the volume of ARB air tank). I measure everything I can think of.

The system has a 135psi cut off & 120psi start up setting. Another 0.9 litre of volume in all of the additional air lines.

Hairyone · Veteran Member

That was supposed to read 1 min 30 secs and 26575R16 from 12 psi to 40.......

Hi Marlene, Lots of answers, some good, but some from compulsive obsessive people who over think life.

If you wish to adjust your tire pressures down to help the terrible shaking on rough roads or to go on sand then you can do that safely knowing you can pump them up to normal pressure again when getting back on the highway. You must not drive at normal speeds unless the tires are back at normal pressures or they will fail.

You might also wish to repair your punctures on the road so you will need a compressor to pump them up after patching them. Or you might have air bags possibly. Relying on the air at service stations to do these things may not work well as often it is faulty or the queue for pumping tires is very slow. You could look at it as a bit of insurance for your own vehicle.

You can buy a portable 12V air compressor at most 4WD shops and other retail car outlets. They plug into the power socket or clip on the battery terminals. If buying one do not get a tiny very cheap one as they are hopeless, get a better one as suggested in this thread.

My daily form of transport is a motorcycle.

I have a compressor for my caravan and tow vehicle, which is a suitably sized unit, but I never ride the bike without a compressor and puncture repair kit in the topbox.

It is made for smaller tyres and is a pretty compact unit, so no matter what I drive or ride, just like the add used to say, don't leave home without it.

A bicycle with a flat tyre yesterday, no surprise with all the screws tradesmen leave on the road as they couldn't be bothered to pick them up. I pick screws up (female as well!) whenever I see them on the street. Could build ends projects!

My car was nearby, plugged bike tyre & pumped up tyre in 1.7412 seconds or there abouts! A very happy customer.

There are some very compact bike compressors on the market. Probably not the best quality, but as a saviour in the rain on a cold night, still worth every cent. At least replace the "repair kit" for next time.

Better than not backup onboard system.

As my farmer son in law is fond of saying - better to be looking at it than looking for it!

Thank you people. Have some good ideas from your helpful posts.

I'm not endorsing this particular unit (probably much to cheap )but I have found twin cylinder units in this
configuration seem to run a lot cooler than there single cylinder equivalents.
