Topic tags/keywords: hvlp hausfeld campbell 2500 hv review used question tip

I’m going to check out a used HV2500 tomorrow and hopefully pick it up if all is well (I believe that it is, but I am yet to know for sure). I was thinking about getting into spraying in a while, just didn’t find anything within my budget, not had a real need for it. The opportunity knocked this time around, and I may as well pick this one up if all works out.

1. does anyone have experience with this model? it is comparable to the Earlex 5000 in terms of quality/performance. Amazon has good reviews – but I was wondering if anyone ‘local’ had experience with it – curious to hear about it?

2. I guess this is more general questions to HVLPs – anything I should be looking for, anything specific to check except for the motor running, and needles being clean?

Thanks in advance,
Peace.

Not much I can offer, but from reading the description on Amazon, it is a 2 stage unit, which means it will have trouble spraying waterbased finishes well. In terms of buying used, as long as it looks clean, the motor runs, and it doesn’t have any holes in the hoses, it should work fine. Even if the needles and gun are dirty, you can always clean it when you buy it, though clean needles is a sign it may have been cared for by the original owner. You might want to spray some water through it to confirm that you can adjust the size of the fan, and the coverage is good. The only way to find out if it can spray waterbased effectively, it to shoot a couple of coats and let it dry, I can’t imagine a seller giving you that much time with it. If you buy it, make sure to buy an organic spray mask.

Aside from good judgement like running motor etc, Check for air leaks in the stem and where where the cup goes up into the gun.

If the seller will allow, fill the gun with water and spray it to see if it leaks fluid anywhere. Most turbine driven guns will have an air shut-off at the base of the handle. Spray a half minute or so, turn the air off to the gun. Now pull the trigger, there should be enough built-up pressure that the gun will shoot a stream of water out of the end. If the water shoots off to the side you have a dirty needle or cap.

If it is going to leak fluid, it will come out between where the cup and the gun meet. This is a gasket that needs normal replacement anyway. If it does leak and it looks like the gasket is ok, turn the empty cup upside down on a flat surface. It should sit flat unless it has been dropped or bent. Also if the cup has lots of dried up finish on the outside, this is cosmetic, its an indicator of how well the gun had been taken care of.

Buying any tool used is a crap shoot. Just use your best judgement. When buying used anything, I always look around at the other items, not for sell, to see how they take care of their property overall.

Thanks guys, those are some good pointers I’ll keep in mind and check for.

barryvabeach – you stated that the fact it’s a 2 stage turbine means it’ll have trouble spraying waterbased finishes well (which is the main thing I’ll be spraying) – why is that? from what I understand waterbased finishes are the least troublesome finishes to spray?

Not an expert here, but my understanding is that waterbased paint has larger particles because it needs to cover the project in a better manner than it could being more diluted. This means that the needles in the spray gun have to be larger (like 2mm), and systems with 2 stages of turbines might have a problem making the coverage even.

I think waterbased stains might be OK to use with a 2 stage turbine.

Thanks Rich,

I’m actually not referring to Latex paint which is indeed very thick and needs the larger needle (2.0mm) but waterbase finishes which according to mfg (both hvlp, and finish) actually requires the smallest needle (1.0mm) which is why I’m wondering why it was stated that this would be an issue with a 2 stage turbine?

I don’t have this specific model, but I bought a ~10 year old HVLP, and I made sure I could get replacement parts for the gun before I bought it, then I just replaced the seals before I even sprayed much with it. Sounds like this model has parts readily available.

My unit is a 4 stage with pressure assist, got it for $250 :) , and it’s a beast. I can spray just about anything that will pour out of a can. For a 2 stage unit, you’re right – it should have no problem with waterborne finishes made for spraying. I think the major issue with waterbornes is that their chemistries don’t tolerate thinning like many solvent based finishes do. There are a lot of great finishes designed for spraying; I’ve had great luck with Target.

Thanks mnguy. sounds like you got a heck of a deal there. as you mentioned the CH does have readily available parts, that was a good point.

It really all boils down to atomizing the finish. You need enough pressure to essentially blow the finish into thousands of tiny particles that land nice and flat on your surface. I don’t see a real issue with the two stage system. Start with a high quality WB finish that is made for spraying and you should have no issues.

I had one of the older CH and it struggled a bit with water based. In general, I have read that 3 stage and 4 stage ( this is referring to how many stages are in the turbine – each stage builds on the stage before ) are better for water based. I built an HVLP using a 3 stage Amtek and it was better than the 2 stage. It may well be true that recent water based finishes are easier to spray with a 2 stage, but I would guess you need a fairly thin water based to atomize properly. Water based finishes are much thicker than nitro cell lacquer ( the standard choice of most pro shops ) and shellac. Shellac and lacquer can be thinned up to 50% so they are easily atomized. Water based is very hard to thin without messing up the ratios – and at best you can thin 5 to 10%.

Thanks for the pointers.

I just picked up the turbine. it seemed in descent shape, just needs some cleaning, the guy was very nice, and over all seems like he’s keeping his stuff well in shape. I sprayed some water, and overall it seems to do well. this is my first experience with HVLP so I was surprised at the amount of air this thing blows, and I knew it’s a bleeder type gun, but I didn’t realize that it blows so much air even when not in spraying mode… I’ll have to get some WB finish and do some practice runs to see how it performs.

Lev,

Sorry, Wrote this before reading that you had already bought the unit.

I just received this ad from Highlands Woodworking. This is an Earlex system, made in England, that has capacity for handling both fine finishes as well as latex paints, per the advertisement. I’d be curious to understand the differences between the 2 systems. Looks like a good deal to me at $149. Take a look!

Thanks Gerry. the Earlex 2900 unit is actually what got me thinking about spraying again, but I decided against that particular unit in favor of a more powerful one. but it does look like a descent unit indeed, I just wasn’t impressed with the gun itself, and the motor specs. I ended up with the Campbell Hausfeld which seem to compare to the earlex 5000 in terms of specs and quality for less than that unit at highland.

Purplev,
I just bought this unit used as well. I have been on the lookout for used turbine units for about a year now. Bought a used Graco 4 stage turbine & gun last summer and have been spraying everything I can ever since. I have been messing around with compressor powered sprayers for about 5 or 6 years and sometimes have had luck and sometimes not. I was almost to the point where i would brush or roll on a finish cause I didn’t want to spray. All of that has changed since I have the turbine. I can now deliver consistent and professional results. I just picked up the used CH unit and am eager to see how it does. Not sure if I am going to keep both but am interested to hear how you make out…

very cool cranky. unfortunately I don’t know if I’ll have much time to check it out as recently I don’t have much shop time (or at all), but I definitely want to at least get some finish, and do some test runs on scrap pieces, and I have a couple of chairs that needs refinishing- so I may run that on them. I’ll post when I have some work with it done. would be interested to hear how you do with it as well… ironic.lol
