Yes it should.
I think if your compressor can maintain 100 at the compressor and 45 at the gun you should be ok.
 The Binks HVLP gravity gun puts out a very high quality pattern.
There are many other gravity guns that should also work just as good.

The Senco air compressor puts out a max of 120 psi.

Is this the gun that is in you pic?

I also have the Fugi Q4 Pro system, and it gives me excellent results every time even with my modest experience with HVLP.

If you are patient, you could keep an eye on ebay like I did. I got my Q4 for less than a third than a new unit, with extras. BUT, when it arrived it had not been cleaned out properly from its last use... a white latex enamel that the cabinet shop used. It took a couple of hours of patient cleaning to remove all the paint, but I think it was still worth it.

No, that compressor will not keep up with CFM demand of a spray gun. It has no reserve tank and  it is only meant to be a portable solution for short burst staple guns or small nail guns that need pressure not CFM output. It will spray, but will run constantly and not keep up and give inconsistant spray, unless your doing small pieces.

Well it does have a tank just not a very large one. :)
Certainly not a compressor I would purchase for this purpose but if you have it already you can try it and see how it holds up. As always go into the chart to compare output with what you will be spraying with.
If you will be purchasing new then do your research and purchase the right tool for the job.
When my 10 hp Ingersol Rand was down for a week we sprayed with our HVLP systems using our installation pancake compressor. Ran all the time but certainly worked.

I bought the Graco 3900 Spray Station at Lowes on Friday.  Sprayed my first canvas today.  Came out great and was very easy to do.  I did spray a scrap canvas first to dial in the spray adjustment and get my technique down.  I started with the adjustment all the way down and started working up.  Eventually I opened enough to get splatter.  Took maybe three or four passes to find the point of too much on the spray adjustment.

A little research on the Graco, and I found out the are made by Earlex.  They are sold under both brands.  Lowes had a Graco 2900 that had a lower wattage turbine.  The 3900 included a "fine finish tip and needle".  The 2900 did not, so I bought the 3900.  It also came with a 1 gallon backpack that looks totally worthless.  Doesn't matter as I don't need it anyway.

http://www.spray-station.com/HV3900.html

A little further research on the Earlex sprayers showed that they make some higher end metal sprayers that are less expensive than the Fuji systems.  I found some woodworking forums that spoke highly of these sprayers.  Might be a worthy mid-price spray system between the Wagner / Graco and the Fuji systems.
The Earlex 3500 looks to be the same gun as the Graco 3900.  The turbine is shaped different.

Also came across this system.  Didn't find reviews on it.  It is also priced between the Wagner / Graco and the Fuji systems.

I've used my spray gun with a tankless compressor and it did ok. I think you'd be surprised with what works. I say if that's the compressor you have, go buy a cheap gun from somewhere that has a good return policy and try it.

Dan's gravity gun has been very well loved.

It has probably outlasted at least the same dollar value of multiple consumer units.  Which is the point of having good equipment.  And the source of the forever irreconcilable dilemma of newbies needing good equipment but not being able to afford it all at once.  Thereby gradually paying the equivalent price of decent, hassle-free equipment by repeatedly replacing broken consumer stuff over a long time scale.  It's vicious.

Anyhoo, before buying any sort of gun check the CFM requirements.  Was at Lowe's yesterday and most of those guns were rated for 5 to 9 CFM.  Less may do, especially for intermittent blasts, you never know.  And up to a point big tanks can make up for low sustained air flow.  Just don't get one of those old bleed style guns, they need lotsa air.

Did a little research on my 1 horsepower Senco air compressor and it only puts our .5 CFM at 100psi. The Binks gun requires a minimum of 3.5 CFM. The compressor can't keep up with the gun. I would have to buy a new compressor and that's going to cost a minimum of $300, and since the gun being $400, I decided to go with the Fuji 3 mini mite. That sells for a standard price of $549 S&H included. I tried looking on ebay and craigslist but no luck. Thanks for everyone's input.

I fail to understand why you (or anyone) needs a $300 spray gun to varnish canvas. We're not spraying flames on show cars, just trying to evenly spread varnish on a flat canvas, something that many people do just fine with a $2 foam roller.

Your right if your canvas is water resistant. If not you need to spray. The Epson Exhibition canvas is not water resistant and I like the way the canvas stretches. My $100 Wagner is plastic garbage. So what to do? I have been rolling for years. No overspray, no waste. Why Epson decided to make a non water resistant canvas is beyond me. But I have to adapt. I tried Lexjet Sunset Matte canvas and bubbles formed when I rolled and sprayed. I am sure there are other canvas and I will look into that.
