Hi would like some feedback on air tanks on board 4x4, my question is are they powerful enough to blow dust off say a camper, much appreciated

Depends on the size of the airtank but generally they allow you to blow for about 20 seconds at a time. Your compressor will then cut in to refill it.

Mark,
I have always had built in compressors and tanks on my 4wds since I realised how much difference it made to keeping things clean. If in a dusty area I turn on the compressor before stopping so it has time to charge the receiver up to 120psi whilst the engine is running. I have found a 10L receiver is quite big enough to blow off the back of the vehicle and a camper trailer when we had one.

The compressor will kick in when down to 80 psi and can usually keep up unless the dust layer is bad. On one vehicle I tried just having a big compressor but found that whilst it was ok for blowing up tyres, it was not good for dedusting.

Mark I blow the spare tyre on the Prado up to 80psi & use a air hose from the spare to blow the dust off the rear door , let takes about 2 minutes to deflate the tyre to 50psi, it only takes about 10 to15 seconds to do this each time,pump it up with my on board compressor when required. John.

Same here, a beaut air pressure storage capability already available. Just mod a hose and your done.

Yep thats the way to go , you get 60 odd liters instead of 10lt tank , and I suggest you make a seperate hose for it, hence you have a full backup system if your main compressor faults and many of hoses etc on those copies really aren't up to it.

You guys might want to check the maximum allowable pressure stamped on the sidewall of your tyres. If you exceed that things may go seriously wrong for you.
The maximum allowable pressure on my tyres on the Hilux is 65 PSI.
At 80 PSI things "may well end up in tears"!

Hi Guys I like that idea, even at 65 psi you would still get a reasonable volume .
Could you explain to me how the plumbing works. I have a LC 200 with the spare under the body.
I would like to have a semi permanent hose from the tire to the rear of the car to which I can then connect the air line for blowing dust off the rear tail gate.
Thanks Craig

My compressor is mounted inside the spare wheel holder on the door, it pumps directly to the spare and that's my tank, 100 litres@ 65PSI. Michael

Often in light truck tyres the pressure on sidewall is not the maximum but rather its the minimum , so worth checking.

For example on my Cooper ST max the sidewall says Max Load 1700kg at 80psi cold.

This actually means that to carry that load it must have a minimum of 80 PSI else its unsafe.

As you could guess when not loaded the tyre can carry much more pressure and 100+ psi is no issue, and makes a wonderful tool for re-seating a bead etc..

Yep that is correct.
One needs to read the tyre & rim information carefully in working out the maximum SAFE pressure for the rim & tyre.

I remember Jack Absolom who used to tour the outback in a Mitsubishi Magna from memory, used to put extra air in his spare to use to top up the pressure in the car tyres.

Forget the compressed air Cliffy.
I use one of these and it would almost blow a dog of a chain.
