Just whould like to know best pressure to spray acrylic enamel never used high pressure gun but came by this modle 7 binks if you can help tell me best may to set it up thanks

because you used activator so the paint will be dried fast, therefore u probably want to paint it in a fast pace. set inlet air pressure at 2 bar, fluid control all the way until the trigger is loose. fan all the way open. paint it closer then normal and move fast.....i dont use activator but that's probably how i would do.

67PD PE Used for Zinc rich and other abrasive coatings, the 36sd is a general nozzle that is used for most applications, if you need assistance,, heres their number Technical Support Tel. 888-992-4657 Fax. 888-246-5732 or you can check their PDF located here . http://www.southernfluidsystems.com/BICONV.pdf

spray gun is cloged (clean it!) also check gaskets in gun and vent hole in cup lid ( could be cloged)

I looked up same gun. I think I googled "binks model 2001 spray gun" and I got a pdf with all info and diagrams. On the available websites, I looked for the one that looked like official Binks site.
The PDF # I got is 77-2316R-14.pdf. It shows that #7 o ring

This model comes in either suction feed or pressure feed. For example a 6211-4307-9 is a suction model. There are different air caps and needles depending on feed style. I assume your'e using either a 82-545 or a 82-555 suction cup attached to the gun. Make sure the tubing is tight, and that the vent hole in top of the cup isn't clogged. See Binks.com for detailed tip combinations.

The only seals I know of that would cause this are around the spindle assembly. If you have changed these then you may have a problem with the seal retainer, a weak spring or bent spindle. Also make sure there are no metal shavings to hinder the sealing. Sometimes they can be left in the gun during machining process.
Hope this helps but if not please let me know and I will try and trouble shoot further.

Worked in paint repair shop for 18+ years. Every time we had that issue it was the wrong air cap. The particular model we always had trouble with was a Devilbiss JGA going from a pressurized system to a 1 quart cup. But the Devilbiss and Binks are quite similar.
The air cap from the pressurized system would actually cause a reverse pressure in the cup.
Both air caps were for this gun. Also the Devilbiss
rep said they should be interchangeable.
They weren't. Try a different air cap.
I'm kind of curious so please let me know if this works for your Binks.
Good luck!

To fix this problem you need to turn up the pressure both at the wall(coming from the air compressor) and at the gun. I would suggest 10 more psi at the wall and 5 at the guns but you can play areound to find whats best for you.

Sounds like you need to completly dissasemble and clean thorougly.
