SOURCE: Air Compressor, low pressure

does the compressor keep running all the time but never gets above 40 or does it turn off at 40?
if it is turning off at 40 I would try using another gauge just to be sure it is 40psi, and if that is the case then you probably have a faulty pressure switch, if the compressor is constantly runnign but won't get past the 40psi then you may have a worn out compressor, check the oil for either a low level or if the oil is dirty, if it is you may just need to drain and refill but if that doesn't fix the issue then you will need to rebuild the compressor

SOURCE: My air compressor is running, but there is a little bit air

Pistons may have lost their seals and not compressing the volume it needs. It's not turning off at 40 correct? That would be the pressure switch. Oil lubed probably like taking a small gas powered engine apart. Check the walls for scoring and such. If none to deep you can get an attachment for a drill to hone them. Auto parts will have that, parts depend on how old but should be at if you have like Sears Appliance repair stocks many different parts for what not. VERY expensive to let them do it but is an option for you. Make sure you have specs for torque and such for the bolts. And your sure no leak or pressure relief valve, yea you would hear that. I wish it was something else.But that's all I can think it would be if it's running continuously.

SOURCE: how do make air compressor shut off at your desired air pressure

You compressor has a pilot valve that controls the tank pressure and the speed of the engine. Locate the brass pilot valve, (It has a flip lever that unloads the compressor) you will notice that it has two locking nuts that allow for adjustment when loosened. Loosen the small lock nut and turn the upper-most part of the pilot valve out to reduce pressure, in to increase pressure. Hope this helps, enjoy.

MT 600101 oil-less compressor, pdf manual. I specifically would like to know the scfm ratings at 40 and 90 psi.


the air flow from a compressor is determined by the capacity of the pumping system
with a piston type compressor it is the bore by the stroke
in a diaphragm type is it is the diaphragm dia by the stroke
that is the maximum cubic feet of air a minute produced
pressure is the resistance to flow so regardless of the pressure or restriction it will only produce that set air flow at that rpms
do not confuse the flow with pressure as it works like this the greater the restriction the greater the pressure in reserve but the less flow in cubic ft per minute through the restriction
for example a compressor producing 10 cubic feet per minute does that with not restriction but with no pressure
at 25% restriction to air flow the pressure in the tank will now rise to say 25 psi and the flow from the restriction will drop to 8 cubic feet per minute
at 50% restriction the compressor is still putting out 10 cubic feet of air per minute but the tank pressure has risen to 50 psi and the flow from the restriction has dropped to 4 cubic ft per minute
go to the extreme end and the compressor is still producing 10 cubic ft of air per minute , the restriction now allows 100 psi in the tank but the low from the restriction has been reduced to 2 cubic ft per minute
the simple equation is pressure = flow X resistance

Compressor runs but only pumps 40 psi


Check your regulator to make sure its set to maximum. When was the last time you drained the tank, it may be full of water.

Convert scfm to cfm? my compressor puts out 4.9 scfm at 90psi; 7 scfm at 40 psi so how many cfm at 23 psi?


Hard to give an exact number, however, as pressure and temp of air increases, the scfm drops as you see in your numbers. With low pressure such as 0 thru 25 the temp of the air is also low/nominal thus the scfm will be very close to the actual cfm listed for the compressor pump.

Can I get 80 psi with dials set at 40 psi


this compressor should be able to fill your tires to 80 psi. Look for a pressure switch and adjust it so the motor shuts off at a higher pressure. Do not exceed 100 psi.

Why does the safety valve go off before the pressure switch on a porter cable 80 gal air compressor


The maximum pressure on most small compressors is 10 bar or 1000kpa which is about 145 psi in the old language most safety valves are set to 150 psi. I suggest you get some one to reduce the pressure switch setting. Running a compressor at elevated pressures does not give you any more air. A reasonable pressure for small compressors is 120 psi

On my 1996 ss impala what low side pressure should I see on the a/c with the system running


It all depends on the outside (ambient) air temperature. Your A/C low pressure switch is designed to turn the compressor off at 24 Psi. and turn it back on at 45 Psi. Most systems will normally run at between 25 and 40 Psi when the system is running on HIGH blower and "MAX" or "RECIRCULATE". A system that is fully charged may run at 25 Psi when the ambient temperature is 75 Deg. (F) and may run at 40 Psi when the ambient temperature is at 90 Deg. (F). (it can be even higher if ambient temperatures are higher than 90 Degrees.)

To properly diagnose a malfunctioning A/C system, the HIGH side pressure must also be checked. Restrictions in the system can make the low side pressure look normal while the high side pressure is high enough to blow hoses apart. (400+ Psi.)

My PRO-SOURCE air compressor will not go over 50 psi


Your compressor has got a 'ring' problem. The rings on the pistons that compress air are leaking air by them and need to be replaced. Unless it's the 'pressure release' leaking. When it gets to 40 PSI or so, unplug it and listen for a leak. If no leak then it's the rings. inside on the piston. If you adjust the pressure switch all the way low, it might shut off near where it builds pressure to and you could at least use it some.
