Professional HVLP Gravity Gun for Clean, Controlled Finishing
Compatible Machines / Setups
Graco 289240 Finex Air Spray Gravity Feed Gun connects to standard finishing equipment. It “fits” the systems below as long as thread sizes and flow requirements are met.
- Shop air compressors delivering ~9.5 SCFM at ~29 psi (HVLP) with ¼ in NPSM air hose connection
- Gravity paint cups / reservoirs with ⅜ in NPSM fluid outlet (standard Finex-style gravity cups)
- Graco pressure pots and paint supply pumps regulated to ≤ 100 psi (0.7 MPa) using appropriate ⅜ in NPSM fluid lines
- Industrial spray booths / finishing lines using HVLP air spray equipment
- Multi-gun manifold setups that can supply the required SCFM per gun
Overview
Graco 289240 Finex Air Spray Gravity Feed Gun is a lightweight, well-balanced HVLP applicator designed for smooth atomization and fine-finish control. Its gravity-feed design simplifies color changes and cleaning, while the precision 1.5 mm (0.059 in) needle/nozzle provides a versatile pattern for primers, enamels, urethanes, lacquers, and more.
Standardized connections (¼ in NPSM air inlet and ⅜ in NPSM fluid inlet) make integration straightforward with common shop air, gravity cups, and regulated paint supply systems. Operate the gun in HVLP range (~29 psi inlet to gun) for consistent transfer efficiency and reduced overspray.
