A friend borrowed my air compressor, then was moving. As I didn't know the exact day he was leaving, I presumed the compressor on "long term loan".
This gave ample time for daydreaming of the next one I would buy. Unfortunately it was given back today. Nevertheless I now know why I spent ages airing up after some fun at lower tyre pressures. I bought the compressor before the patrol. One of those "4wd models at the car compressor price". Flow rate is 70 litres per minute. Don't get me wrong, it works, but I could be 1/4 way home by that time.
So the ultimate is endless air for volume. I ruled that out because of expenses and setup fiddle.
Arb ("Above Retail pBrice") make a nifty twin compressor in a carry box with air tank. It's exxy though. I like it in the way it is its own 'ecosystem' open box, roll out power lead and air hose, and go.
Still, it is only 150 litres per minute. Many compressors reach this. A few questions still plague me.
What is the maximum possible LPM delivered through a schrader (car tyre) valve?
Is there a better way to compare compressors than LPM? This value will change with the pressure inside whatever you are pumping (like a 4cyl car that might do 150km/h,but put a 500kg trailer behind it, and even disregarding stability, will now only do 90km/h).
What is the flow rate required to run an air tool drill, grinder? How much difference will a 5L air tank make to this?
What is the flow rate of a general sized 240v compressor?
I know some people have mounted their compressors behind the trim inside the cab. How noisy is this? I have a car full, and generally no one wants to get out in the rain at the end of the day. Does anyone run sound deadening?
In browsing I came across this http://www.bossairsuspension.com.au/product/com-px07-complete-12-volt-air-compressor/ it offers 170LPM free flow rate, which is the flow rate at 0psi.
I'm not opposed to building my own ecosystem to make a kit like the Arb one.
Are there any advances on flow rate, value for money and adaptability?
