How big is the compressor? if its only say 3 cubic foot a minuet that is at free air pressure not at say 8 bar,,,at 8 bar it would only be 0.375 cubic foot,, check to see how much air in cubic feet per minuet and at what pressure your tools need to work on
if they say 5 cubic feet at 8 bar and the compressor is only 3 cubic feet at 8 bar the tool will only run for a very short time before the compressor air tank has run out of air and the compressor cant keep up with the demand from the tool
the bigger the compressor and the bigger the air tank the better some times,,,for a hammer tool you need 8 cubic foot at 10 bar
thats a big compressor!! or a small one for only a short burst of time,,, in short,,,all ways go for a big un? compressor that is!!
i hope this has helped you out

Will a air compressor that runs at 11.8 cfm at 90 psi run at 10 cfm at 100 psi?


if it is a 11cfm compressor then it produces 11.8 cfm of air regardless of the pressure
pressure has nothing to do with cfm but with the restriction to air flow
for example the tire inflator -air hawk- has a very small cfm but as the tire restrict the air flow the pressure builds up to set pressure on the gauge
so if you want 100psi from the 11.8cfm unit just adjust the pressure switch to shut off at 100psi
Cfm is only important when using air tools as a compressor that is not capable of maintaining the cfm thereby the pressure to run the tools is not a good idea
as an example
a sand blaster that uses 11.8 cfm at 100 psi will not work on your compressor
that unit will require a 20cfm compressor to run it peoperly

First take off the head on the air pump and check the reed valves on the valve plate. If they got hot and warped or cracked they'll work to a point then no more pressure can be built up. Next check the pistion ring and cylinder wall. If either is damaged you'll only get so much pressure build-up then it will leak past the piston.

IT depends on the tool. Some tools require higher cfm. (cubic feet per minute) of air. IF your air line is not large enough, then sometimes 90psi is not enough to operate a tool as there is a pressure drop at the tool. Look at the required cfm for each tool. Find a chart for air line size, cfm and pressure. Most impact wrenches should be used on a minimum 3/8" air hose. You could look at your manual and see what the max pressure is on your compressor. You may be able to decrease the differential pressure e.g off and 100 and on at 90, but then the compressor will cycle more frequently, and may exceed the duty rating of the compressor.

I have a 25 gal compressor and it will not build pressure. The motor runs but will not build pressure. The compressor is about 25 years old


You got a good life time with this. The compressor has seals or "rings" which wear out over time. Replace them and your compressor will love you. It won't hurt to check all the lubrication points. This procedure is easy for even a novice but may require a special tool. Go to your local small engine repair shop and ask. They will be glad to help you.

I'm loosing air on my 3hp air compressor, as soon as i pull that trigger on my compressor for about 2 second it looses air. No holes in the air hose nothing is wrong but just loosing air


Are you talking about the power switch or the trigger of an air tool?
If it is the power switch then how much air are you losing?
At start up most air compressors will lose a small amount of air through the unloader valve. As the compressor builds psi this valve will close. Once the max psi is reached the motor will shut off then a few seconds later the unloader valve will open again releasing the pressure in the cylinder. If your leak does not abate as psi builds you might need to replace your switch and valve.
