The Bobcat B313 delivers the same 0.013” orifice fluid output as the popular B413 — approximately 17 oz/min at 1000 PSI — in a narrower 30° angle that produces a 6” pattern instead of 8”. It’s the right configuration when the material and throughput requirements call for 0.013”, but the substrate geometry, part size, or spray environment makes the 8” B413 fan too wide for controlled application.

The 6” pattern is practical for narrower components — chair legs, table legs, cabinet stiles, rails, moldings, metal extrusions, and any linear or narrow profile where an 8” fan oversprays the target on every pass. It’s also the right choice when spraying into corners or recessed areas where a wider fan bounces back off adjacent surfaces and creates uneven coverage.

The B313 gives you full 0.013” production flow at a 6” pattern — intermediate between the very tight 4” of the B213 and the production-standard 8” of the B413. If your work sits in that range, this is the right angle. Call or text 586-210-0555 to confirm before ordering.

Fluid Tip

36-313

0.013” orifice · 30° angle · ~6” pattern

Same 0.013” orifice as the B413 — narrower 30° angle produces a 6” fan for components and profiles where the 8” fan is too wide. Field-replaceable tip.

Air Cap

26-101

AAA HVLP air cap · ≤18 PSI at handle

Same air cap as all Bobcat configurations. The 30° tip geometry controls the fan width — the air cap refines atomization regardless of angle.

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.

What is the difference between B313 and B413?

Same 0.013” orifice and identical ~17 oz/min fluid delivery at 1000 PSI. The B313 uses a 30° angle for a 6” pattern; the B413 uses 40° for an 8” pattern. The decision is entirely about substrate geometry — choose B313 when your parts or profiles are narrow enough that the 8” fan oversprays the target on every pass. Choose B413 for general panel and component production.

Does changing the spray angle affect fluid delivery?

No — fluid delivery is determined by the orifice size (0.013”) and fluid pressure. Changing from 30° to 40° or 50° does not change how much material the tip passes per minute. It only changes the fan width. The B313 and B413 deliver the same ~17 oz/min at the same pressure — the B313 puts it in a 6” pattern instead of 8”.

Can I use the fan control to narrow the B413 instead?

The Bobcat’s fan control knob does narrow the pattern, but it works differently from changing tip angle — fan control reduces the pattern by restricting air flow, which can affect atomization quality at the pattern edges. For consistently narrow work, a 30° tip that naturally produces the 6” pattern is the correct approach. Call or text 586-210-0555 if you need guidance on fan control vs tip angle selection.

Can I swap tips without buying a new gun?

Yes — all 36-series tips are field-replaceable. If your production mix includes both narrow components and flat panels, you can keep both a 36-313 and a 36-413 on hand and swap between jobs. Call or text 586-210-0555 to order replacement tips.

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.

Where can I find the Bobcat parts manual?
