Description

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.

Why Choose the Finex Gravity HVLP

Fine-finish control with consistent atomization
Lightweight, balanced body reduces operator fatigue
Standard threads for easy drop-in to existing lines
Efficient HVLP operation helps minimize overspray

Setup & Operating Tips

Match threads and seals: ¼ in NPSM air / ⅜ in NPSM fluid
Keep gun inlet around HVLP ~29 psi; regulate upstream for line loss
Use properly filtered, dry air to maintain finish quality
Select viscosity-appropriate needle/nozzle and thin coatings per manufacturer guidance

Frequently Asked Questions

Yes- if your compressor delivers roughly 9.5 SCFM at around 29 psi (HVLP) to the gun and you have a ¼ in NPSM air line (or an adapter). Ensure adequate SCFM margin if multiple guns run simultaneously.

The gun uses a ⅜ in NPSM fluid inlet. For gravity use, pair with a compatible gravity cup; for remote supply (pots/pumps), connect via ⅜ in NPSM fluid line and regulate pressure (≤ 100 psi).

The Finex gravity gun is commonly used for enamels, lacquers, acrylics, urethanes, and other finishing materials. Always confirm viscosity and follow coating manufacturer thinning/pressure guidance for best results.

The 289240 configuration includes a 1.5 mm (0.059 in) needle/nozzle -an all-rounder size for many finishing applications.
