DeVilbiss Advance HD Gravity Feed HVLP Spray Gun Kit (ADV-G507-14)

The DeVilbiss Advance HD Gravity Feed HVLP Spray Gun Kit (ADV-G507-14) is a mid-sized industrial spray gun built for finishing applications with HVLP compliant atomization. This kit includes the Advance HD gravity-feed gun body with the No. 507 HVLP air cap, 1.4mm stainless steel fluid tip and needle, and a 568mL standard gravity cup — ready to spray out of the box. The 507 HVLP cap's wide fan paired with the controlled 1.4mm nozzle delivers fine atomization and smooth film builds across a broad spray pattern — a refined configuration for light to medium-viscosity coatings where finish quality and HVLP compliance are both priorities.

What's in the Kit

The ADV-G507-14 ships with the Advance HD gravity-feed gun body, No. 507 HVLP air cap, 1.4mm stainless steel fluid tip and needle, and a 568mL standard gravity cup (GFC-501). The gun features a 1/4" universal thread air inlet and a 3/8" universal thread fluid inlet (both accept BSP and NPS connectors). Optional accessories include the blue polyester gravity cup for difficult fluids (GFC-511), DeKups disposable cup adapter, stainless steel fluid filter kit (VSA-512), and tungsten carbide or hardened tips and needles for abrasive materials. Hardened and tungsten carbide options are available in the 1.4mm size.

No. 507 HVLP Air Cap Performance

The No. 507 HVLP air cap operates at a recommended inlet pressure of 22 psi (1.5 bar) with an air consumption of 17.3 scfm (490 L/min) and produces a fan pattern of approximately 400mm (15.7"). The 507 is the high-capacity HVLP cap in the DeVilbiss compliant range — it delivers the widest fan pattern available in HVLP with high air volume for fast coverage on large surfaces, all while operating at 0.7 bar (10 psi) at the cap to meet HVLP compliance requirements. The 1.4mm fluid tip provides controlled mid-range fluid delivery that produces a high air-to-fluid ratio with the 507's wide fan, resulting in fine atomization and smooth film builds for finish topcoats, light enamels, sealers, lacquers, and medium-viscosity coatings.

Why Gravity Feed

Gravity-feed spray guns use a top-mounted cup that delivers material to the gun body by gravity. This format offers quick color changes, easy cleanup, and efficient material use — the cup drains completely with minimal waste. The included 568mL gravity cup provides practical capacity for mid-size production runs, touch-up work, and applications where multiple colors are cycled throughout the day.

Built for High-Demand Industrial Finishing

The Advance HD achieves superior atomization through high-capacity air passages and a separate balanced air valve that provides unrestricted airflow through the gun body. The heavily anodized aluminum alloy construction is built for durability in demanding production environments. Stainless steel fluid tips, needles, and passageways come standard for compatibility with both solvent-based and waterborne materials. The gun is CE marked and fully ATEX approved for use in hazardous atmospheres.

Ergonomic Design for Reduced Operator Fatigue

The Advance HD features a contoured handle design that greatly reduces RSI and operator fatigue during extended spray sessions. Increased finger space, lighter trigger pull tension, reduced trigger travel, and a self-adjusting PTFE needle packing assembly all contribute to a gun that is comfortable to use shift after shift. The built-in air inlet adjuster "cheater" valve provides at-the-gun pressure control for quick adjustments without leaving the spray area.
