Air Cap Sets

Fine-tune your spray pattern and atomization with the right air cap set for your gun and material. Browse by gun model below, or use the guidance below to find the right size for your project.

Each air cap set includes a fluid nozzle, needle, and air cap. The nozzle and needle must be the same size — together they meter how much material reaches the air stream — while the air cap can go one size up or down from that pairing to fine-tune atomization. Size by what you spray, not by the gun: thin materials like dyes, stains, and clear lacquers want a smaller nozzle; heavy latex, primers, and filled coatings want a larger one.

Fuji’s Air Cap Quick Reference Sheet (PDF) maps every size against the materials it suits.

0.8 mm: Ideal for ultra-fine applications such as inks, dyes, and touch-up work. Best suited for artists and highly detailed projects.
1.0 mm: Perfect for fine finishing tasks, including water-based lacquers, sealers, and stains. This is a versatile choice for most clear finishes.
1.3 mm: Offers a slightly higher output, making it suitable for automotive enamels, catalyzed lacquers, and latex paints on cabinetry and trim.
1.5 mm: Provides medium output, ideal for spraying walls, ceilings, and larger surfaces with materials like primers and oil-based paints.
1.8 mm: Designed for high output applications, including thick coatings like epoxy, adhesives, and multi-fleck paints.
2.0 mm and 2.5 mm: These sizes are for very high output needs, suitable for industrial primers, texture coatings, and heavy latex applications on large surfaces.

T-Model and M-Model guns ship with a 1.3 mm air cap set and take sizes from 0.8 mm to 2.5 mm. The G-XPC ships with a 1.4 mm set and takes 0.7 mm to 2.2 mm.
