I am in the market for an HVLP system and after a lot of research I have decided on the Fuji Semi Pro 2. I don’t have a lot of experience spraying, so I am trying to decide on if I should get the gravity feed or bottom feed gun. I am looking for some opinions from people who use this gun. In all of my research I have found that one of the benefits to gravity fed guns is the ease of cleaning, but with the way the M gun is designed I think that benefit has been eliminated. I would think that the U shaped tube connecting the cup to the gun would be kind of a pain to clean. I will be using mostly water based products so I suspect that should help make it a little easier, but would like some feed back from actual users.

Also, with either of these guns, how careful do you need to be with the direction you spray (ie spraying straight up or down or in awkward positions)? Is one more forgiving than the other, or about the same? Is there a risk of the finish not being delivered properly or even spilling out?

I think just looking at the two the gravity feed would be more comfortable to use, but without having held either in my hand that is just an assumption. I know Acme carries them and there is a store not to too far from where I live so I’ll have to see if they stock this at that location.

Feel free to offer any other advice I should consider to choose the correct one for me. Thanks.

You’re exactly right that that style of feed pretty much eliminates any worry about which way to go, since you can get aftermarket kits for roughly $30 that can convert from gravity to siphon, and vice versa. Don’t worry about the U-shaped tube making it hard to clean. In everyday cleaning, it’ll just flush out. Unless you neglect cleaning you won’t need to brush it or anything.

My original Fuji gun that came with my turbine (20 yr old Q4) is a siphon. I bought an aftermarket kit that converts it into the same gravity feed profile as the one you’re looking at with the U-shaped tube. I also have an aftermarket gun (see my review) that is gravity feed and feeds at the top of the gun body. Functionally, there’s really no difference. They all do a great job.

Where I do pick a specific one is when I’m spraying lower-sheen lacquers. I leave the lacquer in the gun while I’m doing the job, and sometimes that’s several days. The flattener settles out of the lacquer, and it’s much easier to get it back into suspension with a siphon setup. I can just take the cup and swirl it until it’s mixed. With a gravity feed, it settles down and there’s really no option other than to dump the lacquer, flush it with solvent and refill. Given that some lacquers settle too much to spray in less than an hour, that’s a pain in the butt, so I go siphon for that.

You’re right that the gravity gun is a little easier to clean since you just empty it and flush it a couple of times with the appropriate solvent and you’re done. The siphon gun requires more rinsing and also requires more solvent to make sure you’re reaching the feed tube. Not that big of a deal overall.

The bottom line is, pick one based on what you feel you need right now, and then for a few bucks you can convert it back and forth anytime you need.

Thanks Rich. I did look briefly at the Sprayfine A301 system, but decided on the Fuji based on the number of positive reviews that are out there on that system. Maybe I should reconsider and take a closer look at the Sprayfine. I always over-analyze things when it comes to making big purchases so it is always a painful process for me. My original budget was $300, but the more I looked into it the more I realized I would not be happy with a system in that price range. I tired the cheapy from Rockler a few years ago and was very disappointed so I do not want to end up in the same boat. I also can’t justify paying the price of a 4 or 5 stage system so the 2 stage Fuji looked like it could do what I wanted, but if I’m not going to be happy with the gun and have to put money into that then I would be better off going with the Fuji 3 stage. The T style and Gxpc guns that are available for that look pretty nice.

Anyways, I’m in the middle of a wainscoting project and all of the parts are made and waiting to be finished so I need to make a decision asap.

I’m not suggesting switching brands, Mike. My Fuji has served me well for about 20 years, and I have no experience with the Sprayfine turbine. It’s probably a good one, but if I were out buying something today, I’d stick with the name brands like Fuji, Apollo and others since the turbine is the core of the system.

Aftermarket accessories are another story. The Sprayfine gun in my review is still performing flawlessly and cost less than half what a name brand one sells for. I also got their gravity feed conversion for my Fuji siphon gun and it works perfectly as well. I’ll probably be ordering their touch-up gun down the road too.

The only thing that’s gone wrong with my Fuji was that the lining in the cup started to peel. I spray lacquers almost exclusively and I think it just finally ate through it. I got an aftermarket cup on Amazon for around $13 that’s plain aluminum so that won’t happen again. I also picked up a plastic siphon cup so I can keep it filled with acetone and attach it to the gun for cleaning. It hasn’t arrived yet, so I’ll have to wait to comment on it.

Wow, I thought there were a lot of Fuji guys out there so I guess I expected a better response. Oh well, no big deal. I ended up going with the Mini Mite 3 and the gxpc gun. I figured in the long run the little extra power and the features on the gun were worth the extra cost. Since my wife will be using it as well, I just gave her all of the pros and cons of the Semi Pro 2 and the Mini 3 that I could think of and let her decide. I am pleased with her decision.

I think you made a worthwhile upgrade. Kudos to your wife. You’re a lucky guy.
