Frequently Asked Questions

My spray pattern is heavy on one side. Is it the air cap or the fluid tip?

Spray a test pattern, rotate the air cap one-half turn, and spray again.

  • Defect flips to the other side: the obstruction is on the air cap. Soak it in solvent and clear the horn holes with a toothpick or broom straw. Never use wire; it enlarges the hole and the cap is scrap.
  • Defect stays put: the problem is on the fluid tip. Look for dried paint just inside the opening (wash with solvent) or a fine burr on the edge (remove with #600 wet-or-dry paper).

A loose air cap gives the same lopsided pattern, so tighten the retaining ring first. If cleaning does not fix it, replace the cap: stocked caps include the Binks 66SD and 66SK for the 2100 and the 64HD, 62HD and 704 for JGA and MBC guns.

What do the S, P, E and I letters on Binks air nozzles mean?

They tell you how the nozzle feeds and mixes:

  • E: external mix. Air and fluid meet outside the nozzle; the pattern adjusts from round to a full fan. Most Binks nozzles are external mix.
  • S: siphon type. Will draw material up from a cup; for refinishing and touch-up where you do not need big volume. The 66SD and 66SK are S caps.
  • P: pressure type. Needs a pressure cup, tank or pump pushing material to the nozzle; for production work and heavy fluids. The 68PB, 62HD, 64HD and 704 are P caps.
  • I: internal mix. Air and fluid mix inside the nozzle, so the pattern shape is fixed. Uses less air and makes less fog; for heavy maintenance coatings where a fine finish is not needed. Pressure feed only.
Mismatch symptom: a pressure or internal-mix cap on a siphon cup simply will not spray. Match the cap to the feed before you chase anything else.
Binks 66SD vs 66SK air nozzle: which one do I want on my 2100?

Both are siphon-feed (S) external-mix air nozzles that run with the 66SS fluid nozzle and 565 needle. The difference is air appetite and pattern size:

  • 66SD (46-6020): about 7.9 CFM at 30 PSI and 12.1 CFM at 50 PSI, 10.5″ pattern. The economical choice for smaller compressors. Comes on the 2101-4307-9 outfit.
  • 66SK (46-6082): about 11 CFM at 30 PSI, 15.2 at 50 and 19.5 at 70, 13″ pattern. More air means finer atomization or faster application. Comes on the 2101-4308-8 outfit.
Compressor check: figure 3–5 CFM per horsepower. If the compressor cannot keep up with the 66SK, the pattern will go starved and coarse; drop to the 66SD.
How do I read a Binks 2100 model number like 2101-4308-8?

The 2101- prefix is the 2100 gun. The middle digits encode the fluid nozzle and the last digit the air nozzle, so the number tells you exactly what is on the gun:

  • 2101-4308-8: 66SS fluid nozzle with the 66SK siphon air nozzle (bigger pattern, more CFM).
  • 2101-4307-9: 66SS fluid nozzle with the 66SD siphon air nozzle (less air, 10.5″ pattern).
  • 2101-4300-0: 66SS gun with no air nozzle; 2101-5111-5: 68SS with 68PB pressure cap; 2101-0000-0: bare gun, no set-up.

Use the number stamped on your gun to order the right replacement nozzle, needle and cap, or compare it to the complete-gun-assemblies table in the 2100 service manual. Not sure what you have? Contact Clemtex and we will identify it.
