ADVICE ON PURCHASING A HVLP SPRAY GUN
 
I am planning on purchasing a HVLP spray gun and I am wondering what everyone else's opinion is on this type of gun. I have never used this type of gun yet, but would like to paint my HOTROD this following summer with one. I looked at a Craftsman model but the plastic paint can (where you put the paint) seemed kind of small (smaller than the conventional type) are they all smaller? Can you run the gun completely empty with this type (eliminating paint waste)? How much air pressure would you generally use for HVLP? Does the paint cover more area/go further with HVLP? What else can you tell me about this type of gun? THANKS IN ADVANCE FOR ANYBODYS ADVICE........ <img src="graemlins/mwink.gif" border="0" alt="[mwink]" />

All the pro painters out there will stomp all over me for this suggestion but look at the Harbor Frieght 2 quart pressure pot HVLP. I have painted half a dozen cars with mine and love it. Cost is usually less than $100 (a fraction of the pro Binks, etc.), the free paint head makes painting a car from many weird angles a snap, and the 2 quart cup holds enough paint to do a whole coat w/o stopping. The quality is excellent and the design is a direct rip-off of the high priced units so performance is acceptable too. Obviously, if I were a pro and did high production work, I would spring for the top of the line equipment. For the hobbiest though, can't beat the Harbor Freight unit.

Ok, boys start stomping!!

willys is right, these guns are really getting affordable. you don't have to spend a lot money but make sure that your gun is really adjustable so you can fine-tune your spray, ie. air in, paint volume, pattern nozzle, etc.

psi is usually around 35-40psi going into the gun with about 7-9 coming out the nozzle. don't forget to use a watertrap filter.

I use a Craftsman from Sears.I have sprayed a bunch of paint with it and it dose great. Think it was about 100 bucks.

:D

I bought my hvlp from a semilocal paint store,$90. Advantage brand. I really like how it sprays, never have used a highdollar gun, but the hvlp gun in the harbour freight catalog(#43430-2jja) with the cup on top looks just like mine. I've even thought about buying one to compare.(probably made in the same factory in taiwan)but for what I do it should suffice.

Thats the type I looked at, it was a Sears Craftsman model. It was $130.00 and I coudn't justify spending that much on a gun without knowing how well they work. The gun I am currently using is a conventional type Campbell Hausfield model and they are sold at Wal-Mart for under $40.00. Regardless of the price,I have done some VERY good paint jobs with it. I wonder if it pays to have an expensive gun!!! :eek: :eek: :eek: :eek: :eek:

do u know what HVLP means? are u wanting a gravity fed or suction? in my opinion gravity fed is 100x's better.

collins motors co. 01-16-2003 04:34 PM

hvlp. Is high volume low pressure. Gravity fed hvlp guns transfer about 75 to 80%of material in the gun to the car siphon feed guns transfer about 60 to 65%.So the material savings are a lot with the price of paint.The other thing thats nice is less overspray if your painting in the garage its not as foggy.They make a lot of different tip sizes if your going to buy one gun try to get a 1.5 or 1.6.

From a person who paints everyday, cheap guns are for primer. I have two sata nr95 and two nr2000. They cost about 400 bucks a piece. I use 1.5 tips for sealer, solids and metallics then a 1.3 tip for clearcoats. I have used cheap guns before and you cant beat the quality of these guns. Ive had both of my nr95 for 4 years and they still work like new after using them everyday. Not saying you need guns like mine but you definitly get what you pay for.

What kind of difference does the tip make? Bigger for thicker and smaller for thinner??????Gravity feed is the type I'm interested in. Also,if you just want to paint something small, I am assuming you can mix just a little without having to throw any away like the conventional type because since you have the keep the gun level you can't siphon all the paint out of the can. Am I right or wrong???

Gravity feed guns will use less paint because like you said you can run your gun dry. You dont have any extra like the siphon feed. Tip size makes a difference depending on what your spraying. The smaller the tip the more the paint will be atomized by the gun. This helps reduce your orange peel. Use to big of a tip and the paint will come out in bigger droplets leaving you with to much build and a more orange peel look. I found 1.5 works good for basecoats and sealers and 1.3 for clear. If you dont want to use two guns, some companies make a 1.4 that would work well for an all around gun.

What about the can, plastic vs. aluminum vs. titanium. Will the plastic can warp from thinner over time, causing it to not seal properly? Which is the easiest to keep clean? <img src="confused.gif" border="0">

I like aluminum after a while you can use a little stripper to clean it up.

The Sata 2000 gun is the best HVLP top loader gun on the market. I've been painting almost everyday for 30 yrs. & have tried most guns. The cheaper HVLP guns do not put out enough paint to do a complete repaint. Too small of a spray pattern - you will get a blister on your trigger finger.....try a Sata(most paint suppliers like PPG will loan you one).....Don

If you don't have enough air to drive your hvlp gun you will be very unhappy with it. Most hvlp guns require very high cfm to function properly. One option open to you is the new "high transfer" or "reduced pressure" guns. There are two companys building them, Sata and DeVilbiss. The Sata is caleed an RP and sprays nice but is very expensive and the DeVilbiss is called the Plus gun and it sprays better at a better price, msrp $389.00. The DeVilbiss comes with three different fluid tips for various products and the Sata comes with one. These guns will give you the material savings of the hvlp with a transfer of 70-80% but act and feel like a conventional gun and they use less air, 30lbs in with 10cfm. :D :D :D
