3 gal 2.4 scfm@90osi E100730

3 gal 2.4 scfm@90osi, model may be E100730. It will not pump up to pressure over 10 psi. Sounds like it is really laboring. Oil is in the middle of the "circle". It was cheap...around $100. I can't find the manual and I don't know what the adjustable screwable rings do. Can't find the manual.

    The pressure switch controls the motor starting and stopping at rated pressure. Try adjusting the pressure switch by turning the nut CW to tighten the spring.

Check and see if the air is blowing through the pop off valve...little round plug with a ring hanging off of it. Also, check and see if the regulator has been turned up to a high pressure....air may be blowing through the regulator

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

How do I convert cfm to scfm


For the Equation to follow the following definitions apply

S = scfm (the answer you want)
P = Barometric pressure in Pounds per square inch when you measured the cfm.
14.696 = standard barometric pressure at sea level

So:

S = P/14.73 x cfm

Example: Denver

Barometric Pressure 11.50 psi
cfm = 5400

S = 11.5 / 14.696 x 5400 = 4225.6 scfm

There was a lot of debate in the Natural gas industry years ago about the Standard barometric pressure value. Some Companies used 14.69 psi and others used 14.73 psi.

If you use natural gas to heat your home this is the same equation used by the gas company to correct for altitude on your bill.

The equation is derived from Boyles Law which is accurate at pressures close to atmospheric pressure.

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.

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

One of the factors used to designate compressor power is motor horsepower. However, this isn't the best indicator. You really need to know the amount of air the compressor can deliver at a specific pressure. The rate at which a compressor can deliver a volume of air is noted in cubic feet per minute (cfm). Because atmospheric pressure plays a role in how fast air moves into the cylinder, cfm will vary with atmospheric pressure. It also varies with the temperature and humidity of the air. To set an even playing field, makers calculate standard cubic feet per minute (scfm) as cfm at sea level with 68 degrees F air at 36% relative humidity. Scfm ratings are given at a specific pressure–3.0 scfm at 90 psi, for example. If you reduce pressure, scfm goes up, and vice versa. You also may run across a rating called displacement cfm. This figure is the product of cylinder displacement and motor rpm. In comparison with scfm, it provides an index of compressor pump efficiency. The cfm and psi ratings are important because they indicate the tools that a particular compressor can drive. When choosing a compressor, make sure it can supply the amount of air and the pressure that your tools need.
