Finished my homebrew turbine air supply using a 3 stage Lamb blower and
have A Graco gun sitting in the box. Two questions. Is there a name,
number or source for the guns 3/4 inch quick connect fitting? Can't
seem to locate them at McMaster Carr or Grainger. I need the famale
part that goes on the hose and fits over the gun part. Secondly,
anyone have any luck using any kind of locally available tubing for the
air supply hose. Garden hose maybe? Thanks
Just got back from HD and the large size water hose quick couplers are
an exact match for the male connector on the Graco gun. So Russ and
Craig are correct. I was going nuts looking for something in the air
hose connector line. Who wodda thunk to look in the gardening dept.
Less than $4.00 and fits like a glove. Will have to drill out the auto
water shut off sleave but that's no big deal.
hey Mike. I find myself generally and moderately confused at all times
so don't worry about it. What I built was not a compressor for a
standard spray gun but a turbine that uses a multi-stage vacuum motor.
HVLP stands for High Volumn Low Pressure and is a relatively (10-15
years of so) new way of spraying. It uses a different kind of gun that
uses a LOT of air at a low pressure to atomize the paint. Because it
uses a large amount of air is the reason I needed a special fitting
that is 3/4 inch inside diameter. Turns out it is a water hose quick
connection. Been lots of discussion here over the years on HVLP so you
can serch the newsgroup or DAGS to find out more. Received a couple of
other emails requesting specific info so I will try to post a few
pictures of what I ended up with. Not pretty but hoping it works okay.
Might try it out this weekend. Regards to all who had suggestions. It
helped a lot.
Mike, here is a url to the manual for the gun.
http://www.graco.com/Distributors/DLibrary.nsf/Files/309317/$file/309317a.pdf
This is a url to the turbine I got.
http://www.lambelectric.com/support/prod/11676500.pdf It's a 3-Stage
Tangential Bypass model
Got both the turbine and gun on ebay. The turbine quite cheaply. I
started the turbine up today with 25 feet of 3/4 inch hose on the
outlet. Even without the gun on the end of the hose I was very
suprised at how much air was lost compared to just the outlet of the
turbine unit itself. I've no experience to determine if it is enough
air and decided not to try and spray anything at this time as a couple
of weaknesses in my construction became immediately apparent and I
didn't want to damage the turbine. I will remedy these next week and
try again. I need to secure the PVC adapters I used to adapt the
turbine outlet to the 3/4 inch hose connector. And I need to redesign
how the turbine is mounted to eliminate deformation of the turbine
housing. If results are acceptable I'll post some pics.
Garden hose will work maybe a bit stiff and heavy. Also garden hose quick
couplers work they fit my turbinaire.

The couplers come both ways with or without water shutoff. Just thought you
should know.

Hi Mike-
I do a lot of painting (automotive), and I'm quite familiar with HVLP, but I
have to admit that the concept of a water hose on a gun is a new one on me.
That's the part that bowled me over. I'd be quite interested in seeing the
pics of what you built. How does it spray? Do you have a url for the gun?
Always interested in what folks are doing with this stuff.

The couplers and the air hose are commonly available everywhere. Go to any
auto parts store, Harbor Freight, Home Depot, or just about any of a
thousand other places. No - a garden hose will not work. 50' of air hose
will cost you $20-$30. 25' a little less. Granger has all of these parts.
But like I said - so do those other places. You should probably take your
gun with you and to the auto parts store and let them help you first hand.

Good for ya Mike. Success is always good. So, now you've got me pretty
confused. Can you post a link to your compressor and gun? I'd like to see
what this setup is.

Look at the Milton site for references to the various
quick-connect fittings.
