Hi I saw your post so perhaps I can help you out.
I reciently purchased the 60gal compressor made by Kobalt at my local
lowes store "BTW I believe Kobalt is made by snapon, not %100 sure though"
Kobalt 7 HP (Peak) 60 Gallon Stationary Oil Lubricated Air Compressor
Item # 134819
Model # K7060HFV
The unit runs on 230v. My intent was to purchase a compressor that I
could use with standard hvlp guns, so I took a chance on this one. After
doing much research for atleast 2 months I am glad I bought this compressor
as it meets and exceeds my needs.
I have it plummed in and have a Air dryer connected to ist's output via
brass tubing. I reccomend you purchase a air dryer unit to help keep
water out of your air lines. The air dryer I purchased is available here
and is made by astro. Model 2617.
The air dryer unit has both a 1/4" regulated output and a 3/8" main line output. I use the 1/4" regulated output with a 50ft amaflo 3/8" hose
connected between the dryer unit and my gun. You will need to also purchase
a set of 3/8" industrial type quick connects. There is a pack of 2 available
from sears, they come with 3/8" size nipples. These are far better than the
standard type as they have a larger inner bore so more air volume can flow,
they cost about $17.00 and include various nipples.
BTW, I do not use a quick connect at the tank drier. It is hard wired via a
1/4" to 3/8" short coupler. I use the 3/8 coupler at the end of the hose
and a 3/8" nipple "large inner bore" at the input to my hvlp gun mini regulator.
So basically from the dryer all the way to the gun is a 3/8" line and connectors. This is because you will need to transfer the air from your tank
to the gun with the best volume you can.
For the gun I am using a finex fx300 hvlp 1.4. The gun works really well in
this setup. For this particular gun I run 70psi into the gun to achieve
the 29-psi at the cap. With the gun fully triggered there will be a pressure drop to about 2bar 29psi from the 70 going in.
What to expect. Thus far I have noticed this compressor only produces a small amount of water from a empty tank to a full tank. It reaches full charge from empty in about 3 minutes or so. Using my setup I can paint no problem
with the gun, The compressor will keep up with my gun which is good.
I also use a da on this system. The da I purchased at sears for about $100
is a palm type da. Easy to use and not a real air hog !
Hopefully this info will help you out. I am new to painting and still learning
