HVLP paint guns

[67ster]

Some say the HVLP system is the way to go as you don't blow paint everywhere as with a standard gun , the thing looks clumsy to me but are the results good ?

If you are talking about the cup being on top, it is not a problem. Once you use it , you will never go back to a siphon feed. Another benefit is the fact that you can make very small batches of paint so waste is a minimum.

HVLP

We use an automotive, HVLP gun for painting machine tools. Great improvement over conventional, siphon feed gun. HVLP uses about 30 PSI vs. 60+ for conventional. Minimal overspray and material waste. Same quality results. Hands-down the better choice.

I totally agree here. Our paint usage was cut by about 1/3 when we switched to HVLP. If you have sprayed before, you have to kind of retrain yourself on how to spray. I love mine and would never go back. It is not awkward at all. Lots of old schoolers wont even try them but the fact is they do just as good a job w/less paint/overspray.

I bought one from harbor freight after the mass bumper buy. My Bro in law said I needed a dryer before I used it. Is that so and where do I get one?

I am not sure what he means by dryer, but you should definitely have a water separator on the air line. An air dryer (which is what I think he is talking about) would be quite pricey. We had one in the body shop, but it was thousands of dollars. I am not sure if they make a home variety. I have painted countless things at home w/PPG paint and just use a water separator, drain the tank and I have never had a problem.

He is talking about an air dryer like you said that seperates water from the air. I am setting up a new shop that I just built and I am putting in my air compressor and lines so I will put a seperator in with it. thanks

What you want is a decasent ( I think that is how it's spelled ) filter. Little pellets that dry the air. Did you ever buy something with a little packet of stuff inside plastic in the box ? Same stuff. You can get them for around $250 - $300 if you really look around. For guys painting at home, use a disposable filter on the end of your gun ( little round ball ) they cost about $5 - $7 each and worth every dime. Motor guard makes a nice filter that holds a roll of toilet paper, they work pretty good for filtering water. Hook your hose onto the filter. The motorguard costs about $ 75 - $85 and again, worth every dime. All this filter costs you after purchase is a roll of toilet paper every now and then.

I've got a Fuji HVLP system and love it. It has a 3 stage turbine that produces warm air so you don't get the moisture that you get with a compressor. It works great. I bought it to paint my Bronco and I can use it for doing wood finishing, or just about anything. It sounds like a vacuum cleaner, it's extremely quiet. One of my better purchases.

The TP filters are the way to go, we have two in our shop, one just for the sand blaster, one for the spray gun/other tools, they are cheap, and separate most all the water out of the lines with out the use of a separator.

Well , I am convinced on HVLP , I am not out to purchase the top of the line gun but a good reasonably priced one for hobby use . That TP filter sounds great as I already have a separator but have to blow down the tank to get rid of excess water before painting . My compressor came over on the Mayflower ,actually it's an upright from an old gas station , 5 hp all cast iron and noisy as the devil but it makes tons of air .

A true HVLP system will require and large amount of volume of air to run so be careful what you buy. Make sure your compressor can supply the need volumes.

I am not an expert on this so do your research. When I bought my new gun from spraygun worl I went with the SATAJet RP instead of the model above it. They suggested the RP model for home painting becasue of my compressor.

I haven't spraied with the gun yet. I have a 66 fastback that will get painted in a few weeks with it. I painted my 65 fastback with a Sata90 which I am now using as a primmer gun.

If the noise is a problem try an intake air muffler for air compressors. I put one on mine and it made a HUGE difference. Now I can actually stand being around the thing. Most piston air compressor noise is from the popping on the intake.
