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
My air compressors filled up with air and shut off when the air got below a certain psi and did not kick back in to fill the tank can you help me.
Pressure problems can be several pressureline leaks
If an air pressure switch (pressostat) does not return replace the pressure switch a gray colored or white or black colored box with the powercables comin to and the power knob on it red black gay or other color. that is the problem itself in this case . the mechanic jumped not up it hangs , best is to replace the complete part.
If the compressor filling the tank and when its reached the pressure and it blow from out the safety valve then the pressostat its too high adjusted. there is a max pressure on the valve to read is it blow off below the max replace the safety valve.
Is your pressure is build up but it blow out the Pressure relief nipple its a part of the pressostat in most case , the your Non-return valve on the tank is dirty or by dirtable metal parts from the pressure line membrane parts .
How many gallons per minute can flow thru a 1/4 inch valve with 150 psi
well=== pure water flows at 5.1 gpm thru 1/4 pipe , now valves have a slight orifice to slow the flow down some as a 1/4 valve most likely has a 1/16 orifice value , but that's just an educated guess as I don't know what valve u have , also im assuming your using pure water with a specific gravity of 1.0000 (yes it effects the rate) say hydraulic oil has a value of .0898 this will also slow the flow thru the valve
Why the black push button keep popp out?
It sounds like part of the button has either broken off or wore off and unable to stay in housing. Try typing "Replacement parts for (the maker of compressor) BMM2524" on your search engine and it should show you sites to get new button and housing.
What is the cheapest way for me to achieve 375 cfm at 90 psi
375 cfm is a serious amount of air and there is no way, if continuous flow is needed that it can be obtained cheaply. That is the sort of flow delivered by such things as a towable diesel-powered compressor designed to supply air to a road gang working with a number of air-powered drills and hammers or a large stationary compressor designed to supply a manufacturing process.
Used equipment might be available somewhere near you. I can't really comment further without knowing the purpose, whether it is fixed or mobile and what the air is to be used for.
