Re: How many tools will operate at same time
I think you'll have to look at your specs on your nail guns and see what the demand is . Whether measured in cfpm or psi, your compressor will tell you the max output of each of those. Then you divide the maximum sustained output of the compressor,, lets say it is 60 psi. Let's say the guns require 10 psi, 60 divided by 10 is 6 = 6 nail guns. This is completely hypothetical as I have no idea what your nail guns require, only you know what kind of guns you have.If you need to run more guns than the compressor can push air for, you'll have to invest in another compressor, maybe even one larger to handle the guns running wide open consistent nailing. Nothing a drywaller hates more is than for all the cursed clip nails not being drove in all the way, lol, and that's what will happen with insufficient air supply. Matt

100 psi is capable of running the gun
what the problem is the volume of air supplied to the gun
check the specification requiring the air usage for the gun against the volume supplied by the compressor
if you gun requires 20 c/ft of air /min and the compressor is only capable of 15c/ft of air /min, then the volume is too low so the pressure will not build up
modern impact 1/2 guns will operate quite well on 80 psi unless the gun is leaking internally
another point is this-- impact guns come in two configurations-- single hammer and double hammer
double hammer give 2 hits for each revolution of the air motor and there fore use less air to do the job
add the fact with 2 hammers , the torque applied is generally higher than single hammer units
the reality is this , the compressor capacity in c/ft/min should be 2 times that required or used by the tool
Air tools demand volumes of air; a 10 gallon is good for something like a finish nailer, or staple gun, or even a nail gun.
It will run the impact wrench, just not for very long, like 10 to 12 seconds if you're lucky.
Most compressors tell you what types of tools they are made for.
And impact gun is best matched with a 21 - 26 gallon compressor.
If your using refills that have wire holding the nails together.
Check to see if bits of wire, debris is collecting in around the striking hammer. I switched to paper and never looked back. Must have gone through 5k worth of nails and rarely jams. Other things to check,
1. Check the striking hammer, make sure it is not bent or damaged.
2. Check air pressure, Low pressure can cause jamming, misfires.
3. If the tool needs pneumatic oil, 2-3 drops before you start good rule of thumb.
4. Check spring return. Sufficient pressure must be maintained or the nails will not feed properly. Misfires, incorrect feed, jamming etc.
I had a Hitachi brad nailer and it was horrible. Fire 1 brad nail would jam or misfire. Did everything I could think of nothing worked. Put it up, got a Rigid brad nailer and never looked at the Hitachi again. :)
Sometimes you just get a lemon! (PS I understand you have a framing nail gun. Brad nail gun above is used for an example)
Hope this helps
Pull the dipstick and notice the notch cut into both sides at bottom (push dipstick all the way in to check oil level). Fill to top of notch. Lowest safe oil level is bottom of notch. This unit does not hold much oil. Always use the compressor on level ground (tilted compressor could cause a lack of lubrication). Good luck
I have the same compressor with the same problem. I have temporarily eliminated the thermal reset with a piece of 12 gauge hard wire and it runs just fine. However, I do want to replace it before the warm weather come to the north. I tested the draw at 15.5 amps and the reset was a 17 amp. I am told by someone with superior electrical background that I need to install a 20 amp thermal reset in it's place. I have found that mine runs best when plugged directly into a 20 amp circuit and when using an extention cord I have a 10 guage cord that will carry the load needed to run the EC12. I have changed to 100% synthetic oil at the recomended viscosity (5W50 I believe) and it helps in the cold.
About the best that you could do is compromise between using one cord and more hose. Your compressor draws about 15amps and will probably draw more as the units heats up. One 12 gauge 100' cord will most likely give you enough power to run the compressor (do not use 14 or 16 gauge). (depends on strength of outlet) There is a voltage drop of about 7.5 volts on 100 feet but should deliver 15 - 20 amps. Best to test with meter as compressor runs to prevent damage to capacitors. Now for the hose, that leaves about 250 feet to reach project. Pressure drops in the hose depending on inside diameter up to 40 psi per length. If you used a 1/2id x100 hose at the compressor then the rest 3/8 id or maybe 1/4 you may have enough to power your gun. Another consideration to get more pressure is to use maybe 100' or more threaded pvc pipe or metal pipe 3/4 or 1"id. Finally to get plenty of volume at the gun, you could use a small air tank (3-4 gal) at the end of the run then another jumper hose from the small tank to the gun. Unusual circumstances/challenge makes for unusual solutions. Good Luck on your project.
