The Bobcat B513 is the wide-panel counterpart to the popular B413 — the same 0.013” orifice and ~17 oz/min at 1000 PSI, opened to 50° for a 10” pattern. It’s the natural upgrade from the B413 for operations that move from component work to flat panel production without changing material, pump, or pressure settings.

The B413 at 8” is the most popular configuration in the Bobcat lineup for a reason — the 0.013” orifice handles the broadest range of medium production coatings. The B513 takes that same proven orifice and extends coverage efficiency to flat cabinet doors, wide furniture panels, metal sheets, and other substrates where a 10” fan reduces passes per part. Same material. Same pressure. More coverage per stroke.

The decision between B513 and B413 is purely geometric. If your substrate is flat and wide enough that the extra 2” per pass is an efficiency gain, B513 is the right call. If you’re spraying profiles, components, or narrower panels where an 8” fan already fills the target, stay with the B413. Tips are field-replaceable — keep both on hand and swap between jobs.

Fluid Tip

36-513

0.013” orifice · 50° angle · ~10” pattern

Same 0.013” orifice as the popular B413 at a wider 50° angle — ~17 oz/min at 1000 PSI with 10” coverage for medium production coatings on flat panels and wider substrates. Field-replaceable tip.

Air Cap

26-101

AAA HVLP air cap · ≤18 PSI at handle

Same air cap as all Bobcat configurations. The 50° tip geometry controls fan width; the air cap refines atomization independently. No adjustment needed when switching between B413 and B513 on the same material.

Gun Type

AAA

Air Assist Airless · 1500 PSI max

Requires AAA pump (e.g., Peak 14:1). Pressure settings that work with B413 apply directly to B513 on the same material — the angle change does not affect fluid pressure requirements.

Repair Kits

What is the difference between B513 and B413?

Identical 0.013” orifice and ~17 oz/min fluid delivery at the same pressure. The only difference is fan width: B413 uses 40° for an 8” pattern — ideal for components, profiles, and narrower panels. B513 uses 50° for a 10” pattern — better for flat panels and wider surfaces where the extra 2” per pass reduces total passes per part. No pressure adjustment needed when switching on the same material.

Can I use my existing B413 settings with the B513?

Yes — your fluid pressure and air pressure settings carry over directly from B413 to B513 when spraying the same material. The 50° angle changes only the fan width, not the fluid delivery or atomization characteristics. Swap the tip, keep your settings, and gain 2” of fan width per pass.

What if I need 0.013” with a 12” fan?

The B613 uses 0.013” at 60° for a 12” fan — same orifice, same fluid delivery, wider pattern. If your panels are large enough that 12” coverage per pass is more efficient than 10”, the B613 is the next step up. Call or text 586-210-0555 to confirm the right angle for your substrate width.

Should I keep B513 and B413 on hand at the same time?

Many shops do exactly this. If your production includes both component work and flat panel runs, both the 36-413 and 36-513 can live on the same gun body and swap in seconds. No pressure changes needed between them on the same material — just a 2” fan width difference.

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.
