The Bobcat B619 brings the heavy-body output of the B419 to large flat panel production — a 0.019” orifice at 60° delivering ~36 oz/min at 1000 PSI across a 12” fan. It’s built for industrial operations running heavy primers, epoxy coatings, high-solid enamels, and other heavy-body materials on large flat panels where both orifice size and fan width need to step up together.

The B619 is the second-largest orifice in the 60° Bobcat group and the natural choice when the B615 at 0.015” is not delivering enough fluid for your material viscosity, or when the B419 at 8” is producing the right atomization but your substrate is large enough that 12” coverage reduces total passes and cycle time per part. At ~36 oz/min, it covers large metal sheets, wide structural panels, and high-volume flat panel lines running heavy industrial coatings.

Switching from B419 to B619 carries the same fluid delivery to a wider fan with no pressure change. Call or text 586-210-0555 to confirm the right angle and orifice for your material before ordering.

Fluid Tip

36-619

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

Same 0.019” orifice as the B419 at a wider 60° angle — ~36 oz/min at 1000 PSI with 12” coverage for heavy primers, high-solid coatings, and thick enamels 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. At 0.019”, the AAA air assist refines atomization on heavy-body materials on wide flat surfaces. B419 settings carry directly to B619 on the same material.

Gun Type

AAA

Air Assist Airless · 1500 PSI max

Requires AAA pump (e.g., Peak 14:1). Heavy materials at 0.019” typically run at 800–1200 PSI. The 60° angle does not affect pressure requirements from B419.

Repair Kits

What is the difference between B619 and B419?

Identical 0.019” orifice and ~36 oz/min fluid delivery at the same pressure. B419 = 40° for an 8” pattern — components and narrower panels. B619 = 60° for a 12” pattern — large flat panels and wide substrates. No pressure adjustment is needed when switching between them on the same material. Tips are field-replaceable.

What is the difference between B619 and B615?

Both use 60° for a 12” fan. B615 = 0.015” at ~22 oz/min for medium-body industrial coatings. B619 = 0.019” at ~36 oz/min for heavy primers and high-solid coatings. Same fan width, different orifice and fluid delivery. Step up to B619 when B615 is under-delivering for your material viscosity. Call or text 586-210-0555 to confirm.

Can I carry my B419 settings over to the B619?

Yes — fluid pressure and air pressure settings transfer directly from B419 to B619 when spraying the same material. The 60° angle changes only the fan geometry. Swap the tip and gain 4” of additional coverage per pass, with no other adjustments needed.

Is there a 0.019” option with an even wider fan?

Yes — the B719 uses 0.019” at 70° for a 14” fan with the same ~36 oz/min delivery. If your panels are large enough that 14” coverage is more efficient than 12”, the B719 is the right choice. Call or text 586-210-0555 to confirm.

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.

Where can I find the Bobcat parts manual?
