The Bobcat B411 pairs a 0.011” orifice with a 40° spray angle — the same 8” pattern as the popular B413, dialed down one orifice size for operations running finer materials or requiring more precise fluid delivery control.

The 0.011” orifice is the right choice when lacquers, enamels, or waterborne topcoats are thin enough that the 0.013” delivers more material per pass than the finish requires — causing runs, sags, or excess buildup on vertical surfaces. At 0.011”, fluid delivery drops to approximately 13 oz/min at 1000 PSI, giving you more control on fine finishes without sacrificing the 8” fan width that makes the 40° angle efficient for door and component production.

Same gun body, same air cap, same 6 CFM air requirement, same HVLP compliance as the B413 — just a smaller orifice for finer material control. If you’re currently running a B413 and seeing runs on vertical surfaces or thin materials, the B411 is the next step down before you consider tip angle changes.

Fluid Tip

36-411

0.011” orifice · 40° angle · ~8” pattern

Finer orifice than the B413 — ideal for thin lacquers, enamels, and waterborne topcoats requiring controlled fluid delivery at production 8” fan width. Field-replaceable tip.

Air Cap

26-101

AAA HVLP air cap · ≤18 PSI at handle

Same air cap as all Bobcat configurations — refines airless atomization with a small volume of HVLP air. Finer finish than pure airless at significantly lower CFM than conventional guns.

Gun Type

AAA

Air Assist Airless · 1500 PSI max

Requires AAA pump (e.g., Peak 14:1). Airless fluid pressure provides primary atomization; HVLP air at cap refines the pattern.

Repair Kits

What is the difference between B411 and B413?

Same 40° spray angle and 8” pattern. The B411 uses a 0.011” orifice delivering ~13 oz/min at 1000 PSI; the B413 uses 0.013” delivering ~17 oz/min. Choose B411 when fine lacquers or waterborne coatings are running or sagging with the B413. Choose B413 for general medium-viscosity production.

What fluid pressure should I use with the B411?

Start at 350–500 PSI and increase until atomization is consistent. Fine lacquers and waterborne coatings at 0.011” typically atomize well at 500–800 PSI — lower than the 0.013” because the smaller orifice requires less pressure to achieve good atomization. Do not exceed 1500 PSI.

Can I swap the 36-411 tip for a different orifice?

Yes — all 36-series tips are field-replaceable. If you need to step up to 0.013” for heavier materials, order the 36-413 tip. Call or text 586-210-0555 to order replacement tips.

What pump system does the Bobcat require?

The Bobcat requires an AAA pump delivering 350–1500 PSI fluid pressure. The C.A. Technologies Peak 14:1 is the standard pairing — available in cart mount, wall mount, and portable cart configurations. Call or text 586-210-0555 to configure the right system.

What repair kit does the Bobcat use?

10-137 covers routine maintenance — all o-rings and the seat. 10-138 is the complete kit adding the air valve assembly and needle seal cartridge. CET stocks both for same-day shipment.
