DeVilbiss Advance HD Pressure Feed Conventional Spray Gun Kit (ADV-P430-14)

The DeVilbiss Advance HD Pressure Feed Conventional Spray Gun Kit (ADV-P430-14) is a mid-sized industrial spray gun configured for pressure-feed operation with conventional atomization and a compact fan pattern. This kit includes the Advance HD pressure-feed gun body with the No. 430 Conventional air cap and a 1.4mm stainless steel fluid tip and needle. Gun only — no cup included. The 430 Conventional cap delivers a focused, tightly controlled spray pattern with fine atomization — paired with the 1.4mm nozzle's controlled fluid output, this configuration produces a high air-to-fluid ratio through a compact fan for smooth, precise finishing on light to medium-viscosity coatings.

What's in the Kit

The ADV-P430-14 ships with the Advance HD pressure-feed gun body, No. 430 Conventional air cap, and 1.4mm stainless steel fluid tip and needle. The pressure-feed configuration connects to external fluid supply systems including pressure tanks, remote cups, and recirculating lines. 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 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. 430 Conventional Air Cap Performance

The No. 430 Conventional air cap operates at a recommended inlet pressure of 50 psi (3.5 bar) with an air consumption of 12.0 scfm (339 L/min) and produces a typical fan pattern of approximately 200mm (7.9"). The 430 is the most compact-pattern conventional cap in the Advance HD range — it concentrates the spray into a tight, finely atomized fan that puts more material on target with less overspray than wider-fan caps like the 497. The 430's moderate 12.0 scfm air consumption also keeps compressed air demands lower than the high-capacity conventional caps, making it practical for shops with limited compressor capacity or multi-gun setups. The 1.4mm nozzle's controlled fluid delivery combined with the 430's focused pattern and conventional atomization pressure produces an exceptionally smooth finish on smaller parts, narrow surfaces, profiles, and detailed work.

Why Conventional Atomization

Conventional spray guns operate at higher air pressures than HVLP or Trans-Tech compliant guns, producing the finest atomization and smoothest finish quality available. Where regulatory compliance permits, conventional atomization delivers the highest finish quality and fastest application rates in industrial spray finishing. The 430 cap's compact pattern concentrates the conventional atomization advantage into a smaller footprint, making it especially effective for detail-oriented finishing.

Why Pressure Feed

Pressure-feed spray guns deliver material from an external pressurized source rather than a gravity or suction cup. This eliminates the weight of a cup on the gun body, reducing operator fatigue on long spray sessions. More importantly, pressure feed enables continuous material supply without stopping to refill — a critical advantage in high-volume production and applications where consistent fluid delivery is needed regardless of gun angle or orientation. The Advance HD pressure-feed body maintains the same high-capacity air passages and balanced air valve as the gravity and suction versions for identical atomization quality.

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.
