Description

Compatible Machines & Systems

Graco 289259 Finex Air Spray Gravity Feed Gun is a universal, compressed-air HVLP finishing gun. It is not tied to a single sprayer model if your setup meets the air/fluid specs below, it will work.

Shop/commercial air compressor systems with regulator & filter (air inlet 1/4 in NPSM)
Top-mount gravity-feed cup assemblies for small/medium jobs
Remote pressure pot / fluid reservoir feeds (≤ 100 psi), with suitable adapters
Spray booths & finishing lines using compressed-air HVLP/conventional air setups
Graco/aftermarket air regulators, hoses, moisture traps matching 1/4 in NPSM air fittings
Portable air supply carts with filter/dryer where clean, dry air is required

What this product is

Graco 289259 is a compact Finex mini gravity-feed HVLP air spray gun built for fine-finish control and reduced overspray. It pairs ergonomic handling with a precision 1.2 mm (≈ 0.047 in) nozzle/needle set and a non-bleeder design for clean atomization on wood, metals, plastics, and more.

Key benefits

HVLP efficiency for transfer rate and overspray reduction
Lightweight, ergonomic body for long spray sessions
Integrated air inlet cheater valve for quick on-gun adjustment
Handles a wide range of coatings: waterborne, solvent-borne, urethane, epoxy, sealants, high-solids (within spec)

Frequently Asked Questions

No. It is a compressed-air HVLP gun. If your air supply (¼ in NPSM) and fluid setup meet the pressure (≤ 100 psi) and material compatibility requirements, it will integrate without a dedicated sprayer machine.

Yes- use appropriate adapters/hoses and keep the fluid pressure ≤ 100 psi. Ensure your coatings and wetted parts are compatible.

Fine-finish waterborne/solvent-borne, urethane, epoxy, sealers, and many high-solids materials (within viscosity limits). Thin/condition per coating supplier guidance for HVLP atomization.

Stable, clean, dry air supply with 1/4 in NPSM connection. Start low and increase to target atomization; typical booth/shop compressors are suitable. Install filter/dryer to prevent defects.
