Hi, Pat. Good to see a new post from you!
I am not familiar with that exact model, but it may indeed be something from the Earlex line, which is a mix/match of parts from different vendors. It seems that it matches closely in some features and performance. In fact, if you DAGS the Graco HV3900, you will get results from the Earlex HV3900. Hmmmm.......
I have used some of those type of sprayers and I find that they have their place. I think it depends on how much you are going to use them, and what you will use them to spray.
I can point out what I see as the pros and cons.
Pros:
- The unit is cheap. And if you don't like it you can return it immediately. Lowe's has a generous return policy, so you can woodshed the machine in practical application to see if it will work for you.
- Graco will undoubtedly offer different aircaps (on less expensive units they are needle assemblies only) that will allow you to spray different types of finish. Keep in mind that many finishes today are made to spray, and are quite forgiving. If I am reading this correctly, the larger unit comes with a 1.5mm aircap, which is a bit small for latex with a 2 impeller turbine. This will make it good for project sized work, but you can't throw enough material out of the machine to make it a fast painter. At 1.5mm, you will undoubtedly need to thin, and that will need you time to experiment to get it right.
- The largest unit comes with a bigger reservoir. Unless you doing small work like doors, a bookcase, the one quart cup is a pain. You need both.
- I believe (IIRC, I saw these at a Sherwin Williams home center display) the two larger units have two impellers. Although not ideal, this is adequate for spraying clean, thinned latex. I had a friend that bought a used Earlex (sold by WoodCraft) that was a 2 module turbine that he used to spray enamel onto doors in his residential paint business. He thinned properly, then sprayed away. IF YOU USE A GOOD PAINT, you can thin the daylights out of them and still get a great finish. He used the SW line mostly, and hit it with about 15% water and it sprayed out like glass. The good finish was part excellent paint, part application technique, part machine. Thinning is the key on these smaller machines
Cons:
- If you are painting anything of size, say a house or a house interior, you will work yourself to death with this thing since even with the larger reservoir they don't carry a lot of material
- You need to learn how to thin paints. Some only need a little, some more. I would start at 10% and study the dried (2 hours) surface and see if I had the texture I wanted. Spray on a slick carboard box (such as those that house electronics) and you can see every imperfection. Don't thin past 20%. Don't tell anyone you thinned to
20% either or you will hear a wall of baloney that will make you wince.
- The 1.5mm aircap isn't good for everything, BUT with thinning practice and good material you should be able to put down a good finish in paint. The good news is that the 1.5mm should shoot all kinds of clear coats with minimal thinning. I would bet that if you hit your lacquer or poly about 10%, you would be fine.
- I HATE HATE HATE those 6' long hoses they put on the units. They don't give you any maneuverability, don't allow for ease of movement, and don't let you get the gun motion right. I am 6'2", bare foot. Unless I put the unit on a 5 gal paint can I can't reach the ceiling or even the top of a door with that 6'. Fortunately, since the air supply is all that is carried in line, you can add what you want or in some cases buy another hose. This isn't a problem is you are using the shoulder tank, but it is ugly when painting a project in your garage
So in the end, my thoughts are this: If you want a machine for light use that will turn out a pretty good finish, this could be a good buy. $140 is pretty tough to beat. On a bigger project or even a couple of smaller ones, it would pay for itself in time and effort. It won't due heavy work, and without practice won't turn out really good finishing. But I wouldn't hesitate to use it as my buddy did, to spray latex on doors, trims, built ins, and project work. He loves that thing for shutters, too. He actually used it so long his guys called it the "trim machine".
Not that you are actually that interested, but this could be a good machine on which to learn to spray, too. I have always thought that
1/2 of good HVLP end product was learning to thin, and that takes practice.
If it was a two impellor model, I would buy it and try it. If it was just one, I would skip it.
As always, hope that helps!
