This airbrush set contains two popular, internal-mix airbrushes. Both are dual-action (triggers control air & fluid, pressing trigger releases air, pulling back releases material) with balanced, precision-crafted bodies. Each utilizes fine-finish, stainless needles to minimize tip-dry, and tight-tolerance heads for superb atomization and razor-sharp detail. The PZ-204 features a low-profile, gravity-feed 2cc color cup. Needle backstop at allows you to pre-set the trigger travel; helping produce consistent line widths. Micro Air Control (MAC) valve below the color cup provides on-the-fly, micro-adjustment of air pressure. Four-piece head; pre-installed 0.2mm nozzle (tip), nozzle cap, needle, and removable, crenelated needle cap (crown-shape cap minimizes air turbulence near the tip; allowing airbrush to be held very close to the working surface) for a spray pattern between hairline and 1". Cutaway handle for easy cleaning and access to the needle chuck. The PZ-128P features a siphon-feed 22cc glass bottle. Initial-flow control; set screw can hold trigger partially back, so material flows at the pre-set rate as soon as trigger is depressed. Pre-installed 0.35mm nozzle, nozzle cap, needle, removable needle cap and protective nozzle cap (spray pattern from thin-line to 1.5"). Boxed set includes barbed hose connector, nozzle wrench, paint pipette, 6' hose, instruction sheet and adapter for 1/4" air sources (1/4" BSP female to 1/8" BSP male). Extra nozzle and needle are also provided for each brush (0.3mm for the PZ-204, and 0.5mm for the PZ-128p). Airbrushes and hose have standard 1/8" BSP fittings. Working pressure of 15 to 50 psi required. As an added bonus, access to the following exclusive airbrushing guide downloads is included: Top 8 Cake Airbrushing Tips, Guide to Airbrush Cake Decorating, Developing Basic Artistic Skills, 10 Essential Airbrushing Tips, Airbrushing Strokes and Techniques, Airbrush Cleaning Manual, and the Airbrush Lettering Guide.
