Description
DeVilbiss GPG Gravity HVLP Gun Kit with 900mL Cup (905012)
The DeVilbiss GPG Gravity HVLP Gun Kit (905012) is a multi-purpose professional spray gun configured with the GPG2 HVLP air cap and three nozzle sizes that span the full range from basecoats to sealers and enamels. This kit includes the GPG gravity-feed gun body with the GPG2 HVLP air cap, 1.3mm, 1.5mm, and 1.8mm stainless steel fluid nozzles, matching multi-purpose fluid needles, HAV-501 air inlet adjustment valve with analog readout, and a 900mL aluminum gravity cup — a versatile package that covers light-viscosity basecoats through medium-viscosity sealers and enamels without changing air caps.
What's in the Kit
The 905012 ships with the GPG gravity-feed gun body, GPG2 HVLP air cap and retaining ring (905230), 1.3mm fluid nozzle (905260), 1.5mm fluid nozzle (905261), 1.8mm fluid nozzle (905264), multi-purpose fluid needle for 1.2, 1.3, and 1.4mm nozzles (905267), multi-purpose fluid needle for 1.6 and 1.8mm nozzles (905268), HAV-501 analog air adjustment valve (180089), and a 900mL aluminum gravity cup (702576). The gun features a 1/4" universal thread air inlet. Additional fluid nozzles are available separately in sizes from 1.2mm through 2.2mm. The GPG platform also accepts high efficiency cap (7E7), primer air caps (PR10, PR30), and conventional caps (C86, C30) — all sold separately.
GPG2 HVLP Air Cap Performance
The GPG2 HVLP air cap operates at a recommended inlet pressure of 22–26 psi (1.5–1.8 bar) with a maximum air consumption of 15.9 scfm (450 SLPM) and produces a fan pattern of 11.5–12.0 inches (290–310mm). The GPG2 is the wide-fan HVLP cap in the GPG range — it delivers the broadest spray pattern with high air volume for fast coverage on large surfaces while maintaining HVLP-compliant atomization. The GPG2 supports the widest nozzle range of any multi-purpose cap in the GPG lineup, from 1.2mm through 2.2mm, making it the most versatile HVLP option for shops that spray a variety of materials. With three nozzle sizes included, the 905012 covers the broadest material range of any GPG2 kit with a 900mL cup. The 1.3mm is the workhorse size for standard-viscosity basecoats and single-stage finishes. The 1.5mm bridges the gap between basecoat/clearcoat work and heavier materials — well-suited for thicker clearcoats and light sealers. The 1.8mm handles sealers, enamels, synthetics, and medium-viscosity coatings where higher fluid output is needed. This nozzle spread makes the 905012 the most versatile single-gun solution in the GPG HVLP range.
905012 vs 905013 — What's the Difference?
The 905012 and 905013 include the same GPG2 air cap and the same three nozzle sizes (1.3mm, 1.5mm, 1.8mm). The only difference is the cup: the 905012 includes a 900mL aluminum gravity cup while the 905013 includes a 560mL Acetal gravity cup. Choose the 905012 when you need the larger capacity for bigger jobs, or the 905013 when a lighter, smaller cup is preferred.
