That was the price range I was looking at and decided to go the
compressor/conversion gun route. With an 80 gallon tank, it was about
the same price. iirc, the turbine units don't have the possible
moisture problems that a compressor might have. But a filter and dryer
should fix that problem. And with the compressor, you get to use it
for other things possibly getting a better value for the money.

Wagner model NB gun SoftSpray 2900 turbine $580

Features to look for

Non-bleeder gun - no air flow out of tip unless trigger
is pulled. No air blowing your finish around after applying.
An air relief valve diverts the airflow either in the hose
line or at the turbine.

Unless you're using a pressure pot, most HVLP spraying
is done with a siphon feed which diverts some of the
airflow to pressurize the finish cup. Better guns
have a check valve in that line to keep finish from
getting into parts of the gun that aren't supposed to
come in contact with it. Only necessary if you need
to tilt the gun - like inside cabinets

Multiple air ports - air line that can attach to the
gun either at the bottom of the handle or the back of
the gun - or both.

Air cap adjustment - when the air holes in the cap
are "up and down" you get a horizontal fan, holes
"left/right" gets you a vertical fan, and at 45's you
get a circular cone. Some caps have detentes (click
stops) at these three positions. Being able to change
spray patters without having to unscrew the cap
is real handy.

Ability to control both amount of finish flow and
fan width - two knobs on the back of the gun-handy

Test was done with oil based poly, lacquer and water
based vanish. Accuspray, Fuji and Turbinaire required
no thinning of any of the test finishes. Others required
15-50% thinning. Accuspary and Turbinare were
rated Top Tool, with the C&H HV2002 rated as
Top Value.

The article noted that "conversion" guns require
air flow CFMs that require at least a 30 gallon
compressor and an 80 gallon preferred.

Hey Max,

I'm looking to sell my graco 4900 procomp if you're interested. I've
used it a few times and it's just more than I need It's a 4 stage
2-speed turbine that comes with 2 guns. One is a siphon gun with a 1qt
cup and the other is a remote with a 2qt cup on a 6' whip hose. The
procomp has a built in air compressor to move the fluid from the remote
cup to the gun so everything's built into the turbine box itself. It's
a 4 stage turbine (I've sprayed latex with it) and is very clean. It
comes with tip sets #2, #3, #4, #5, and #6.

Here's the manual if you want more details:
http://www.graco.com/Distributors/DLibrary.nsf/Files/309242/$file/309242k.pdf

It cost over $1500 brand new and I was going to list it in the
classifieds this spring (when tool demand goes up) for $900.

I appreciate the info, Mike, But I really haven't had much luck with used,

I understand. I buy a lot of used tools too but prefer to do them
locally so I can see the shop as well as the tool to get an idea of
whether they've been taken care of or abused.

Max,
You are obviously a new shooter (spray, that is). Buy the cheapest setup
you can find and practice, practice, etc. The most expensive turbine system
you can afford, or take a loan out for, will not make you an expert. If you
got the bux, buy the top of the line (and practice, practice, etc.).
Are you a professional woodworker or a hobbiest? Seven-fifty or more is a
lot to pay for 'sometime usage'.
Think about it,

about thirty years ago. Some of my recent projects are he

I've also sprayed a few repair jobs on vehicles that came out looking really
nice.
I'm more of a hobbyist than professional, although I've done several jobs
for pay. We spend too much time traveling now in our RV to get involved in

I'm looking for a quality spray system that will create less overspray and

The Accuspray 230K looks like a reasonable compromise.

Ouch. That would be an important point to me. When trying to get into
corners, tight places, touch up, etc., an adjustment down to a very fine
pattern is a must. A basic fan with no real adjustment - which is what you
really have with a 5-8" or 5-10" fan, is about useless.


I have a touch up gun that I use for a small fan pattern but it's not
HVLP.
Hmmm.


Gotta love touch up guns, but I sure would not want to have to dirty two
guns everytime I went to spray something. The spraying part wouldn't bother
me, but I'd sure be grumbly at cleanup time.

Hello Max,

I hope you don't mind me joining in on this discussion.

Unfortunately, the author, Paul Snyder, is really not that
knowledgable about HVLP Sprayguns. This is quite understandable
because that is not his chosen field. It is mine however.

The way the spray pattern on our spraygun is adjusted is identical to
the Apollo, Turbinaire (bleeder gun that they manufacture themselves,
the non-bleed gun is not their manufacture), American Turbine,
Lexaire, Wagner, Titan, Capspray and more.

You can spray from about 15" down to 1/8".

What Paul does not understand is that nobody - even if they have a
'knob' to adjust the size of the fan patter - paints let's say, a 3/4"
spindle on a chair from 8" away. This is what he is judging his
premise upon. If you did this, you would need a very steady hand
indeed. Remember, you have no bristles to guide you.

No... what people do with all the sprayguns listed in the article is
switch to a round pattern, reduce the amount of 'paint' and move in
close. With hvlp turbine guns, you can actually touch the gun on what
you're spraying without it flying back in your face.

The same goes for spraying a 3" length of trim. Set to a vertical
pattern, adjust how much paint (to allow you to move the speed you
want to go) and move the gun in until the pattern becomes 3". Then it
is exactly like painting with a 3" brush (but with no bristles).

The adjustment for size is to turn in or out the collar at the front
of the spraygun. From 8" away, he is correct - it's about 4 - 5" in
size. But you have to move closer anyway so it's not an issue.

Incidentally, Paul Snyder also mentions (and makes quite a big deal of
it) that the cups are all Syphon-Feed. Well of course, they're not.
They are all pressure-feed. I would like to ask Paul to fill the cup
with water and remove the Pressure Tube on any of the sprayguns
sampled. Then I would want him to pull the trigger and wait until the
water came out of the nozzle. It never will. There is absolutely no
syphon feed action whatsoever at those low pressures. The gun cannot
even syphon water never mind paint!

And if anyone is interested, I can tell you about the filtration
system too.

Best regards from Fuji Spray.

I would be very interested in hearing more about the filtration system,
and the air control valve vs. varying the speed of the fan (as in the
Turbinaire system).

system too.

Paul Smith

Hi,

I replied to 'Sawblade' (good name!) by e-mail but it seems others are
interested. So here is what I e-mailed to Sawblade.

1A) The filtration system. In the Wood Magazine article, they gave us
a B- because of the filter system. They said in a box to the right of
the ratings that the filter was difficult to replace because it was
inside the case. The filter is not inside the case - it only looks
like it is to the uninformed. If the author had raised up the case to
look underneath he would have seen that the filter enclosure is
completely open from below. You can remove the filter in 2 - 3
seconds - it simply slides out.

It takes a bit longer to replace it because you have to ensure that it
fills the whole enclosure - about 10 seconds maximum.

So we really should have received an A rating on the filter but the
author misunderstood the facts.

1B) I don't know if the author was marking us on this or not but we
use a combination, much thicker fine filter on our Q-Series but 2
filters (they call them dual in the article which is a misnomer) on
our less expensive systems.

The combination filter is superior because it allows you to use a
thicker filter. That is because the 3 or 4 fans (5.7" diameter) pull
in a lot of air into the case. It is inside the case that this air
divides up into the air for the cooling fan and the air to the much
larger 3 or 4 fans. Usually, the cooling fan has its own separate
filter and this restricts air being sucked in. There is absolutely no
restriction to the cooling fan with the combination filter, so it is
better for supplying more air to the cooling fan.

To avoid restricting the air to the cooling fan, we have to use a
coarser filter on our less expensive units. Once again, this is not
necessary with a combination filter.

2) The reason you would want to turn down the turbine or psi/cfm is so
that you can spray with less pressure. Doing this would allow you to
spray with less overspray and bounceback.

If this control is at the turbine and knowing that the turbine should
be placed at least 20ft away from the spray area, it means that you
would have to walk 40ft to make the change to psi/cfm. Plus, if you
didn't adjust it enough, or you went too far, you would have to make
the same walk again.

So it's really not practical to have the control 20ft away when you
can have it right at the gun for tweaking anytime you want to.The
author did mention this and got it right.

3) Although you didn't ask, we (fujispray) were a little perturbed by
the fact that with our total ratings being A x 8 and B- x 2 we were
not rated a 'Top Tool'. And yet, with 6 x A, 3 x B- and 1 x C-
Turbinaire was. When I was in school, if the kid next to you got
marks like this, he was placed somewhere down the list behind you.

Oh well, the world is not perfect.

I'll echo a "me too". I really don't know diddly about turbine systems, so
anything that came out of this discussion would be interesting to me.

Paul,

Thanks for the rapid follow up. I was at the Woodshow in Houston this
weekend, and the Turbinaire guy was really touting the benefit of
reducing the speed of the turbine instead of just putting a valve in
the line. Since you guys chose the valve, I am sure you have studied
the pros and cons beyond just the walk to the turbine and I was
wondering if there is a tradeoff here. It seems that running the
turbine full blast all the time would be worse for it than slowing it
down to only produce the pressure necessary for the task at hand. Also
is the control that you guys use a valve or a regulator? I know it
should not be this hard, but the learning curve is pretty steep at
least in the beginning.

Thanks,

Sawblade

For what it's worth, I've got an HVLP that has it's a air flow adjusted
near the gun. I wouldn't want to keep treking across the room to screw
around with controls at the turbine. that would be a deal breaker for
me. I don't follow you regarding the issue of the turbine running "full
blast". You should get years of service from a high quality turbine.
Are you concerned about the noise? Guess what--you'll likely run the
thing close to if not at, full throttle anyway!

Dave

Hi Paul,
I have used both the Turbinaire (own one) and the Fuji and would give a slight
preference to the Fuji. But your comment about setting the air flow by walking
back and forth does not really reflect reality. I know that when spraying
shellac I want a 20% setting. When spraying WB urethane I want a 45% setting and
so on if I keep the same N/N. So it is not a problem. Cheers, JG

Hi Sawblade,

The motors used in all the turbines are not specifically made for
HVLP. They are common vacuum bypass motors of the type that you may
have in your basement (with hoses you attach to different locations in
the house).

When you place a regular vacuum cleaner tight on the floor, you are
restricting the air passing through and this causes the vacuum motor
to speed up a little and you can even hear the change in pitch. These
motors are designed to take that pressure change with no problems
whatsoever.

About 10 years ago we spent a couple of thousand dollars to make a
prototype speed control for our turbines. When I called the technical
people at Ametek-Lamb Electric to ask some advice, they advised us not
to do it. They told us that not only does it change the speed of the
main 3 fans (on a 3-stage motor), in turn, it also changes the speed
of the cooling fan. This is because the small cooling fan is mounted
onto the same shaft as the main (much larger) fans. I thought that the
motor wouldn't get as hot going slower but the technician assured me
that the windings still get just as hot and so do the bearings.

In this same conversation he advised us to simply go with an air
control valve and that's when he explained to me that the motors were
built to take that kind of change in pressure.

So we've been using the same valve (but from different makers over the
years) and never had a problem with it or the motors.

Paul,

Thanks for the rapid follow up. I was at the Woodshow in Houston this
weekend, and the Turbinaire guy was really touting the benefit of
reducing the speed of the turbine instead of just putting a valve in
the line. Since you guys chose the valve, I am sure you have studied
the pros and cons beyond just the walk to the turbine and I was
wondering if there is a tradeoff here. It seems that running the
turbine full blast all the time would be worse for it than slowing it
down to only produce the pressure necessary for the task at hand. Also
is the control that you guys use a valve or a regulator? I know it
should not be this hard, but the learning curve is pretty steep at
least in the beginning.

Thanks,
