Description

Professional Overview & Key Benefits

Compatible Machines / Systems

Graco 289239 Finex Air Spray Gravity Feed gun is an HVLP-style finishing gun. It “fits” systems that provide clean, regulated compressed air and standard gun connections.

HVLP-capable compressed air compressors with adequate CFM (typ. shop compressors/regulators)
Spray booths / finishing lines using 1/4" NPSM air inlet hoses & regulators
Finex gravity cups and standard gravity-feed accessories
Inline air regulators/filters and moisture traps used in HVLP setups
General woodworking, cabinetry, furniture, and light industrial coating stations

Tip: If your setup uses 1/4" NPSM air fittings and supports HVLP pressures/flow, this gun will integrate with minimal adapters.

What is it?

Graco 289239 Finex Air Spray Gravity Feed gun is a lightweight, ergonomic HVLP gravity gun designed for smooth atomization and control on light-to-medium viscosity coatings. It’s ideal for fine finishing on wood, metal, and general industrial parts.

Key Features

Balanced, ergonomic body with light trigger pull for reduced fatigue
Consistent HVLP atomization for fine finishes and reduced overspray
Integrated air adjustment at the handle for quick tuning
Standardized connections for easy drop-in to existing lines

Use clean, dry, filtered air (add moisture trap/regulator if needed)
Select nozzle/needle appropriate to coating viscosity and desired build

Frequently Asked Questions

Yes-its air inlet is 1/4" NPSM, which is widely used on shop air lines. If your hose uses a different thread, a simple adapter usually solves it.

It’s optimized for light-to-medium viscosity materials—waterborne/solventborne clears, lacquers, stains, enamels, and many urethanes. For very thick coatings, consider a larger nozzle or different spray technology.

No. This is an air spray HVLP gun designed for compressed air systems, not for high-pressure airless pumps. It belongs on spray booths or compressor-driven stations.

Start low (per coating tech sheet) and increase only until proper atomization is achieved. The gun typically operates up to ~100 psi, but most HVLP finishing is done far below that.
