Gravity-fed design keeps paint flowing directly to the nozzle without pressure drops or feed interruptions. Iwata's HP-C Plus positions its 9ml cup right above the paint channel, creating a short, straight path that responds instantly when you adjust the trigger. That direct route also means thorough cleaning in minutes rather than extended disassembly sessions, rinse the cup, flush the channel, and you're back to work.

The 0.3mm needle and nozzle combination handles the range most artists actually need: fine enough for controlled detail lines, open enough for smooth background coverage and varied stippling effects. This mid-size configuration works across different viscosities without constant needle changes or frustrating clogs. Mix custom colors directly in the cup, test your blend, adjust as needed. Gravity does the work of feeding paint to the tip while you control flow and spray pattern through trigger pressure and distance.

Dual-action trigger operation puts both air and paint under your direct control, press for air, pull back for paint, adjust the balance between them for everything from hairline details to broad, evenly atomized coverage. Replacement needles work across both HP-C Plus and HP-BC Plus models, giving you backup options without maintaining separate parts inventories. This airbrush handles illustration, fine art, model finishing, and craft applications with the reliability Iwata builds into their professional equipment.
