The Bobcat B611 takes the 0.011” orifice — the same used across the B211, B311, B411, B511, and B711 — and opens the angle to 60° for a 12” pattern. At ~13 oz/min at 1000 PSI, it delivers fine finish quality at the 12” fan width that makes it efficient on large flat panels, wide cabinet work, and any application where a 10” fan still requires too many passes.

The 0.011” orifice keeps fluid delivery in the fine-coating range — suitable for production lacquers, waterborne topcoats, fine conversion varnishes, and similar thin-to-medium materials where mil thickness control matters on large surfaces. The 60° angle is the widest practical angle for typical flat panel work before moving into the 70° category where the fan becomes very wide and pass overlap management increases.

The switch from B511 (50°, 10”) or B411 (40°, 8”) to the B611 requires no pressure adjustment on the same material — the angle change only affects fan width. Keep all three tips on hand if your production spans narrow components, medium panels, and large flat work. Call or text 586-210-0555 to confirm before ordering.

Fluid Tip

36-611

0.011” orifice · 60° angle · ~12” pattern

Same 0.011” orifice as the B411 and B511 at a wider 60° angle — ~13 oz/min at 1000 PSI with 12” coverage for fine lacquers and waterborne topcoats on large flat panels. Field-replaceable tip.

Air Cap

26-101

AAA HVLP air cap · ≤18 PSI at handle

Same air cap as all Bobcat configurations. The 60° tip geometry controls fan width; the air cap refines atomization independently. Settings from B411 or B511 carry directly to B611 on the same material.

Gun Type

AAA

Air Assist Airless · 1500 PSI max

Requires AAA pump (e.g., Peak 14:1). At 0.011”, fine lacquers and waterborne coatings atomize well at 500–800 PSI. The angle change to 60° does not affect pressure requirements.

Repair Kits

How does B611 compare to B511 and B411?

All three use the same 0.011” orifice and deliver ~13 oz/min at identical pressure. The only difference is fan width: B411 = 40° for 8”; B511 = 50° for 10”; B611 = 60° for 12”. No pressure adjustment needed when switching between any of them on the same material. Choose based on your substrate width alone.

Can I carry my existing settings over from B511 to B611?

Yes — fluid pressure and air pressure carry directly when spraying the same material. The 60° angle changes only fan geometry. Swap the tip, keep your settings, and pick up 2” of additional coverage per pass. Tips are field-replaceable in seconds.

What if I need 0.011” with a 14” fan?

The B711 uses 0.011” at 70° for a 14” fan — same orifice, same fluid delivery, maximum width. If your panels are large enough to benefit from 14” coverage per pass over 12”, the B711 is the right move. Call or text 586-210-0555 to confirm the best angle for your production.

Should I keep multiple 0.011” tips on hand?

Many shops do — keeping 36-411, 36-511, and 36-611 on the same gun means you can match fan width to substrate width on the fly with zero pressure adjustment between them. If your production spans narrow profiles, mid-size panels, and large flat work with the same material, this is the most efficient setup.

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. Most in-stock orders ship same day — stocked at C.A. Technologies’ Colorado facility.
