Question about Northern Industrial 2 Hp Twin Tank Electric Air Compressor

1 Answer

Hello, I have a stacked twin tank framing air compressor and it will not pressurize past 65 to 80 psi, so it never shuts off... even when I turn the pressure "out" valve way down to below what should be 65 psi nothing happens. As it builds compression from 0 to 65 or above the amount of air blowing out the air filter intake increases enough to blow the cap off the air filter housing. I think it is the one way "check valve" but I am not sure how to check that other then ordering one and replacing it to see what happens... It may even be the pressure "out" valve regulator but I can't seem to find a part number or how to check that. Any ideas or need more info? Jon

Sounds like the inlet valve in the cylinder head is passing and requires renewal

Why will my bostitch pancake compressor 240 psi tank 180 regulator that the guages will not show building pressure


Hi, There are different posibilities. I would need more information. Was it always like that? Does the guage on the main tank and the guage on the regulator both not show more than 20psi? When the auto shut-off is triggered do you feel there is more than 20 psi in the tank?

Builds up air pressure ,motor shuts down


We are distributors of all plastic materials, including complete fabrication of plastic parts, components and assembles like Acrylic sheets, polycarbonate sheet and UHMW.


1)Turn off your compressor or disconnect the power.
2)Remove the connector tube that sends air to the tank.
3)Remove the head bolts on top of the pump.

With full tank of air, compressor turns over slow then kicks out motor reset button


Hi, my name is John. Welcome to FixYa. Check your pressure switch, it,s only supposed to build up to 135 psi and shut off, then back on when the pressure gets below 105 psi, check the oil level. thanks for choosing FixYa. ..John

I have a model FP209501 Air Compressor 2 Gallon,


2 gallons is small to begin with u need to buy an in line pressure adjuster/regulator their a few bucks and can be attached to the paint gun or line and will keep the pressure at ur adjustment the regulator on the tank sets the tank pressure at 50 so when u us it will let it drop down to about 45 than start up to build the pressure up to 50 than shuts off than repeats it self the inline keeps pressure steady even if tanks are at 200 psi

I changed the regulator twice and the compressor still does not stop at the psi where i want it.


The pressure regulator adjusts the line pressure! The pressure switch is what turns the pump on and off. If you are trying to maintain a line pressure with the switch and not the regulator,,, you are never going to accomplish that. I would have to guess that your compressor normally run's between 95~125 psi on the "switch" so if you adjust your pressure regulator to 110psi it will maintain that till the tank pressure drops below that point. then it will drop as low as 95 until the pump restarts again. If you are trying to get the switch to run up higher than that,, "stop now" as you will only burn the thing up by trying to go higher that it was designed to run at from the factory!

Hitachi twin stack problem.


You stated that the compressor started up fine. I'll assume it reached it's max psi then cut out. Then upon reaching it's cut-in psi the motor ran slowly for a few seconds, then kicked off. I also assume you mean check valve when you refer to the non return valve.
If this sounds about right then. The first thing I would do is bleed out all the air from both the tank and the pump supply line leading from the pump head to the tank's check valve. You can do this by simply loosening the fitting that attaches the line at the head or the check valve. Once done try running the compressor again.
The purpose of this is to check the unloader valve. This valve bleeds off the pressure that remains in the compression cylinder and the supply line up to the check valve. When functioning normaly it will bleed off this pressure once the motor shuts off. If it is not working correctly then when your compressor starts back up (once it is already been filled) the piston will be working against a psi close to the max psi.

If the problem reoccurs only after the compressor has reached it's max psi, then the unloader valve is most likely the problem. If however it will not start up at all even after a complete bleed then it has to be something internal to the pump and\or motor.

Please try this and let me know (or repost) your findings.
If it's the unloader valve I should be able to explain how to repair this valve.
Good luck.

Air compressor pressure not regulating


Usually you cannot adjust the cut out pressure of the tank/motor itself, this is why they have regulators, which regulates the pressure flowing down the air lines (regulators like these dont regulate actual tank pressure cutout). To regulate air flow using the regulator knob, you actually have to have air flowing through the hose while you make the regulator/pressure adjustments as regulators regulate pressure DOWNSTREAM from the actual regulator itself.. so air flowing through is a must. Attach an air blower or something similar and let air start flowing through the hose. Now turn your regulator knob in the "-" direction to decrease regulated pressure. It is best to bring pressure all the way down to "0" first, then open the regulator up (by turning to the "+" side) and pressure will rise until you get to the desired pressure needed for the air tool in use. The tank pressure will still be between 80-125 PSI as the motor regulates and keeps the pressure in the tank between these values automatically, but your line/hose air flow pressure will remain at the regulated pressure (say 40 PSI or whatever you set using the regulator knob).

Hope that helps and makes sense.

Not pumping up to capacity, motor and compressor working fine,


If your pump is shutting off before it reaches it's max psi. then you need to adjust you switch. Under the black case there are two adjustment screws. One is the high\low adjustment, the other is high pressure cut off.
The first will change when the pump turns on and off for your low psi setting and the high setting simultaneously.
The second will allow you to raise or lower just the high setting. There should be a diagram under the black cap to show which is which. Adjust the high side only and just a 1\4 turn then run the compressor and see if that takes care of the high setting.
