Professional Overview & Key Details
Graco 289244 Finex Air Spray Gravity Feed Gun is a conventional, gravity-cup finishing gun designed for clean, controlled patterns on automotive, industrial, wood and general finishing tasks. It features a 0.055 in (≈ 1.4 mm) needle/nozzle, adjustable fan, and robust construction to handle a wide range of solvent-borne and water-borne coatings.
Compatible Machines / Setups
This gun “fits” systems that supply clean, dry compressed air and a compatible fluid feed. Common compatible setups include:
- Air compressors with 1/4" NPSM air line (regulated, clean & dry air up to 100 psi)
- Gravity cup supply (standard top-mount paint cup)
- Pressure pot / paint pot systems up to 100 psi fluid with appropriate 3/8" NPSM connection
- Graco finishing rigs that support conventional air spray guns (bench carts, booth lines)
- Spray booths for automotive refinish, cabinetry, furniture, and light industrial finishing
Why Choose the Finex 289244
- Gravity-feed design for efficient material flow and quick color changes
- Conventional air spray atomization for smooth, high-quality finishes
- Adjustable fan & fluid control to dial in pattern and film build
- Durable build with aluminum body and stainless-steel wetted parts
- Versatile materials: epoxies, urethanes, lacquers, enamels, water-borne & solvent-borne coatings (within viscosity range)

Frequently Asked Questions
No. Graco 289244 is a conventional air spray gravity-feed gun, not HVLP. It uses higher atomizing air than typical HVLP setups.
Provide clean, dry, regulated air up to 100 psi via a 1/4" NPSM air line. If using a remote pressure pot, ensure fluid lines and regulators match the 3/8" NPSM inlet and do not exceed 100 psi fluid pressure.
The 289244 handles a wide range: epoxies, urethanes, lacquers, enamels, and properly thinned water-borne and solvent-borne coatings. Always follow your coating’s data sheet for thinning and filtration guidance.
Yes—when configured with a remote supply, the gun supports pressure pot systems up to 100 psi using the 3/8" NPSM fluid connection. Verify seals, hose ratings, and regulators match system pressure.
