DeVilbiss part numbers explained

If you have ever stared at DV1-C-BAR-13-B+ on an invoice and wondered what half of it means, this is for you. DeVilbiss part numbers look like noise — but the DV1 range is completely readable once you know the pattern, and reading it saves you ordering the wrong gun.

The DV1 code, decoded

DV1 – C – BAR – 13 – B+

family · cup · gauge · tip · air cap

DV1The model family.
C / UC comes with the gravity cup. U is gun only.
000 / BAR000 is standard. BAR has the digital pressure gauge in the handle.
13Fluid tip in tenths of a millimetre — so 1.3mm.
B+The air cap. B and B+ are basecoat; C1+ and C2+ are clearcoat.

C or U — what's in the box

C means the gun arrives with its gravity cup. U means gun only.

The most common ordering mistake we see. A painter orders a U code expecting a complete kit, and a gun turns up with nothing to put paint in. Already have DV1 cups on the shelf? U saves you money. If not, you want C.

000 or BAR — the digital gauge

Worth understanding rather than dismissing as a gadget. The gauge reads inlet pressure at the gun, not at the wall regulator. Between your regulator and your gun sits hose length, couplers, and a compressor that sags the moment someone else starts using air. All of it eats pressure.

Set by the wall gauge and you are guessing. Set by the gun gauge and today's clear lays the same as yesterday's.

The two digits — fluid tip size

Tenths of a millimetre. 13 is 1.3mm, 10 is 1.0mm, 15 is 1.5mm. That is all there is to it.

Tip size	Typically used for
1.0 – 1.2mm	Clearcoat and light metallic basecoat
1.3mm	The all-round bodyshop default — most shops run this if they run one
1.4mm	Heavier basecoat and sealer
1.5mm +	Primer and high-build

The suffix — air cap

This is where basecoat and clearcoat guns diverge, and it is the part most people get wrong.

Cap	What it does
B	Standard basecoat cap
B+	Wider fan — better on larger panels and full resprays
C1+	The everyday clearcoat cap. Suits most 2K clears
C2+	Moves more material. Comes into its own on higher-solids clears and full panels

A DV1 Basecoat and a DV1 Clearcoat are not the same gun with a different sticker. The air cap and the atomisation behind it are set up for different jobs — coverage without mottling on one, flow-out and gloss on the other.

The rest of the range

Here is the honest bit. Outside the DV1 family, DeVilbiss part numbers tell you nothing. 905052, 905100 and 905114 are sequential catalogue numbers with no embedded meaning. You cannot work out the tip size from the code — and neither can we. Go by the description, or ask.

One suffix you may still see. -CB denoted the Carbon Edition — a limited-run carbon-wrapped body. It was cosmetic: a 905157-CB sprayed identically to a 905157. The Carbon Edition has now been discontinued, so if you see one listed elsewhere it is old stock. The standard PROLite is the same gun to spray.

PROLite air caps

The PROLite — which you may still know as the GTi PRO LITE — uses named air caps rather than coded ones. Choosing between them makes more difference to your finish than almost anything else on the gun.

Cap	Best for	Air use	Fan
TE10	Standard water and solvent basecoats, air-dry and MS clears. The all-rounder	280 lpm 9.9 cfm	290–310mm
TE20	Clears, especially HS and UHS. Higher flow than the TE10	350 lpm 12.4 cfm	285–300mm
TE25	As TE20, with a narrower fan	350 lpm 12.4 cfm	270–285mm
T110	Higher-solids clears. Widely regarded as the most forgiving cap in the set	265 lpm 9.4 cfm	260–290mm
HV30	True HVLP. Waterborne basecoat and clear, maximum transfer efficiency	460 lpm 16.3 cfm	300–325mm

Check your compressor before you choose. The HV30 asks for 16.3 cfm. If your compressor cannot sustain that, the cap will not perform — and you will blame the gun. All of these want roughly 1.5–2 bar at the gun, which is not the same as 2 bar at your regulator.

Names that changed

DeVilbiss has renamed several ranges, which makes hunting for spares harder than it should be.

Old name	Current name
GTi PRO LITE	PROLite — same gun
GPi	GPG — same gun

If you have an older gun and are looking for parts, search the current name.

Gravity, suction or pressure?

Feed	How it works, and who uses it
Gravity	Cup on top, feeds down. What most bodyshops use for colour and clear
Suction	Draws from a cup below. Useful for larger volumes, or where a top-mounted cup fouls the panel
Pressure	Fed from a pot or pump. Production kit — sprays all day without refilling and moves heavier materials. Commercial vehicle, plant and agricultural work

Worth knowing: a pressure-feed gun on its own is not a working setup. You need the pot or pump too.

Which gun, roughly

Gun	What it is for
DV1 Basecoat	Flagship colour gun. Metallics, pearls, low-VOC
DV1 Clearcoat	Dedicated lacquer gun, tuned for flow-out and gloss
DV1s	The small one. Smart repair, spot work, blends
PROLite	The UK bodyshop default. Composed on difficult materials
GPG	The workhorse. Primers, synthetics, 2-pack commercial
