Spray Gun Feed Styles: Bottom-Feed vs. Gravity-Feed.

• Gravity-Feed:  With the cup above the gun, gravity-feed models are perfect for smaller jobs and tight spaces. They offer better maneuverability and are easier to clean, making them a favorite for detailed work like cabinetry.

• Bottom-Feed:  Ideal for larger projects, these guns have the fluid cup beneath the gun, allowing for higher capacity (up to 1 quart). This setup is well-balanced and reduces the need for frequent refills, making it suitable for extensive spraying tasks. 

All Fuji Spray spray guns work with all their HVLP turbines.

After selecting the spray gun, you will need to consider the air cap set.

T-Model (T70 & T75G): These are Fuji’s premium spray guns, known for their lightweight design (20% lighter than standard HVLP guns) and ergonomic Stay-Cool handles. They feature a side-mounted Pattern Control Knob for easy adjustments and provide excellent atomization for a professional finish.

M-Model (7001 & 7002G): Often bundled with Fuji’s 2-stage systems, M-Models are budget-friendly and versatile. They come in both bottom-feed and gravity-feed options and include rear-mounted controls for fluid and fan adjustments. While slightly heavier, they offer reliable performance for hobbyists and occasional users.

Each air cap set includes a fluid nozzle, needle, and air cap. It’s essential that the fluid nozzle and needle match in size, while the air cap can be adjusted one size up or down to fine-tune atomization. Factors like material viscosity, ambient conditions, and desired finish quality may influence your choice. It’s often beneficial to experiment with different air cap sizes to achieve the best results for your specific project.

• 0.8 mm:  Ideal for ultra-fine applications such as inks, dyes, and touch-up work. Best suited for artists or detailed projects using the GXPC or Sunless spray guns. 
• 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.

Fuji Spray guns come with a 1.3 mm air cap set.
