Hi Rezarf <>
I see that you removed the plastic covers round the cylinders. This may improve the cooling.... if the intake air was not being used to pull air around the cylinders for cooling. I have not pulled one apart to check what is under the plastic cylinder covers.
I would like to share some experience and general information with everyone. I am sure some of you already know this but think of this a refresher.
All air compressors get hot, the higher the compression the hotter they get. If it dose not get hot it is not compressing air.
Installing a air tank, positive and negatives;
First the bigger the tire the more air it requires to fill it. By putting a air tank you can; Add to the cubic feet of air required to reach the pressure you want. This requires additional time to reach this pressure. This can be offset if you have a pressure regulator switch wired into the system and it fills while the vehicle is being driven and the tank is filled when you start the filling of the tires. This can be also done by a inside switch that you turn on before you stop giving you a tank with compressed air to begin with. This also requires a pressure relief valve for safety. This will give you a extra shot of air at first. When the tank balances out with the pressure in the tire. Then you have the tank space you have added to the cubic feet of air in the tire, required to get the tire up to the desired pressure. This now takes longer to reach the desired pressure, because of the tank. Depending on the size of the tank, size of the tire and cubic feet of the compressor(s), this will vary the time.
Having a tank can allow you to turn on the compressor and run it while you check your pressure or move between tires. This gives you a little shot of extra air when you first connect the air chuck.
Having the tank takes up space and adds weight and additional plumbing requirements. Yes, I know people use bumpers, roll bars and more to be air tanks. It can be done but if not done correctly it can become a bomb.
Having the extra shot of air is good for seating the bead of a tire.
Now note that each compressor has a Duty Cycle! Example; This means that if a tire takes 4 minutes to get to the required pressure you have a 50% duty cycle then you need to wait 4 minutes for it to cool.
4 tires X 4 minutes each = 16 minutes run time.
4 minutes cooling time between tires (we will skip the last cooling time while you burn your fingers putting it away). 4 minutes cooling time X 3 cooling periods = 12 minutes
Total filling time 16 + 12 = 28 minutes
When people have the cheap compressors that have a very low duty cycle. You can stretch this out to 1 hour or more to fill 4 tires.
Now the people who fill a set of 4 tires with no cooling period between tires you will burn up the compressors. That is why people do not have good luck with cheap compressors. Yes, there are bad compressor made and it may be that you did nothing wrong, it was a piece of "Junk".
You need to have the “correct tool for the job”. Example; You would not want to have a 16 ounce ball-peen hammer and a splitting wedge to split a log. I splitting maul would be better (in my opinion), but I could be wrong also.
Disclaimer; Do not try any of this at home without proper supervision and training. Doing so you may hurt yourself and/or people around you or you may just look stupid.:Wow1:
