The Bobcat B613 is the large-panel counterpart to the most popular configuration in the Bobcat lineup — the same proven 0.013” orifice as the B413, opened to 60° for a 12” pattern. It delivers ~17 oz/min at 1000 PSI with the maximum practical coverage width for large flat production work before moving to the 70° group.

The B413 handles the broadest range of medium production coatings at 8”. The B513 extended that same orifice to 10”. The B613 extends it to 12” — the right choice when your panels are large enough that each additional inch of fan width meaningfully reduces total passes per part and total cycle time per piece. Large cabinet doors, wide furniture panels, full-sheet wood and metal substrates, and high-throughput flat panel lines where production lacquers, conversion varnishes, or medium-viscosity industrial coatings are the standard.

Switching from B413 or B513 to the B613 requires no pressure or air adjustment on the same material. The 60° angle changes only fan width. Call or text 586-210-0555 to confirm the right angle for your substrate before ordering.

Fluid Tip

36-613

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

Same proven 0.013” orifice as the B413 and B513 at a wider 60° angle — ~17 oz/min at 1000 PSI with 12” coverage for medium production coatings 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. B413 and B513 settings carry directly to B613 on the same material.

Gun Type

AAA

Air Assist Airless · 1500 PSI max

Requires AAA pump (e.g., Peak 14:1). Pressure settings from the B413 or B513 carry directly to the B613 on the same material — the 60° angle does not affect fluid pressure requirements.

Repair Kits

How does B613 compare to B513 and B413?

All three use the identical 0.013” orifice and deliver ~17 oz/min at the same pressure. B413 = 40° for 8” — components and narrower panels. B513 = 50° for 10” — mid-size flat panels. B613 = 60° for 12” — large flat panels. The B613’s 12” fan is 50% wider per pass than the B413. No pressure adjustment needed when switching between any of them on the same material.

Can I carry over my B413 settings to the B613?

Yes — fluid pressure and air pressure settings transfer directly from B413 or B513 to B613 when spraying the same material. The 60° angle changes only fan geometry. Swap the tip and pick up 4” more coverage per pass compared to the B413, with no other adjustments needed.

Should I keep B413, B513, and B613 on hand?

Many high-volume shops do exactly this. All three use the same 0.013” orifice on the same gun body, air cap, and pressure settings. Swapping between tips lets you match fan width to substrate width instantly — no pump or pressure changes needed when spraying the same material on different substrate sizes.

What about a heavier material at 12” fan width?

The B615 uses 0.015” at 60° for 12” at ~22 oz/min, and the B619 uses 0.019” at 60° for 12” at ~36 oz/min. All three share the same 60° angle and 12” fan. Call or text 586-210-0555 to confirm the right orifice for your material viscosity.

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.
