- HVLP air gun – uses a compressor, not an airless sprayer
- Needs ~10 SCFM @ ~30 psi clean, regulated air
- 1/4" NPT air inlet; on-gun air adjustment
- Lightweight, smooth trigger for reduced fatigue
Precision HVLP side-cup gun for clean, controlled fine-finish spraying
Compatible Machines / Setups
This is a stand-alone air spray (HVLP) gun. It does not mount on Graco electric/airless sprayers (Ultra, GMAX, Mark series, etc.). It “fits” any setup that provides clean compressed air and cup-fed material.
- • Any air compressor capable of ~10 SCFM @ 30 psi (or higher), with 1/4" NPT air line and regulator/filter.
- • Shop or booth regulated air supply systems used for finishing lines.
- • Graco or third-party air/HVLP finishing rigs that supply compressed air (non-turbine).
The Graco 24J599 Finex Air Spray Gravity-Feed Side-Cup Gun is a lightweight, ergonomic HVLP spray gun with a swiveling side cup for better access in corners and tight spaces. Supplied with a 1.2 mm (0.047") needle/nozzle, it’s ideal for clear coats, stains, sealers, and other fine-finish materials where pattern control and a smooth surface are critical.
Key Features
- Swiveling side-mounted gravity cup improves reach and visibility.
- HVLP performance for high transfer efficiency and reduced overspray.
- 1.2 mm setup targets fine-finish, lower-viscosity coatings.
- Integrated on-gun air adjustment (“cheater” valve) for quick dialing-in.
- Lightweight body and smooth trigger pull for reduced fatigue.
