DeVilbiss FinishLine (line)

FinishLine HVLP gravity guns are a well-established entry point into automotive and furniture spraying, with multiple tip sizes and available parts.

Not for: Owners of small compressors that cannot deliver the gun's CFM continuously, and painters who want premium atomization for show finishes.

Ingersoll Rand Edge Series 210G

Gravity-feed design and adjustable spray controls make it a versatile choice for furniture, automotive touch-ups, and other small finishing projects.

Not for: Users without a suitable air compressor or those painting large walls.

Iwata (brand)

Iwata guns are known for excellent atomization in professional refinishing.

Not for: Occasional hobby use.

Air consumption. Your compressor must deliver the gun's rated CFM at its rated pressure continuously, not just at tank peak. Starved guns spit and orange-peel.
Fluid tip size. Use about 1.3 to 1.4 mm for basecoat and clear and about 1.7 to 2.0 mm for primers and heavier coatings. The tip must match material viscosity.
Gun type. HVLP is limited to 10 psi at the air cap; compliant or LVLP guns use less air. This sets transfer efficiency and compressor demand.
Air quality. Use a water and oil separator at the gun or the regulator. Moisture and oil cause fisheyes.
