Part 0277090 is a projector set used on compatible SprayTech HVLP systems to shape, direct, and control material flow at the spray head. The projector set plays a critical role in spray pattern formation, helping ensure even atomization and consistent coating distribution during operation.

The 0277090 Projector Set is a spray-head component designed to control how material exits the gun on compatible SprayTech HVLP equipment. Working together with the air cap and fluid components, the projector set helps guide coating material into a consistent, well-defined spray pattern.
Worn or damaged projector components can cause uneven fan patterns, poor atomization, spitting, or inconsistent coverage. Replacing the projector set restores proper material flow control and improves overall spray quality.
| Pattern control | Shapes and directs material flow exiting the spray head |
|---|---|
| Atomization support | Works with air components to help achieve uniform atomization |
| Coverage consistency | Helps maintain an even, repeatable spray fan |
| Distorted spray pattern | Fan shape becomes uneven or inconsistent |
|---|---|
| Visible wear or damage | Erosion, scoring, or deformation of projector components |
| Poor atomization | Spitting, heavy droplets, or streaking in the finish |
| Routine service | During spray-head rebuild or performance restoration |
Part 0277090 is compatible with the following SprayTech HVLP system. Always confirm fitment and orientation using the correct parts diagram for your exact unit.

Spray-head performance issues are often tied to multiple wear components.
Damaged air caps can affect atomization and fan symmetry.
Worn nozzles can disrupt material flow and overload the projector.
Needle wear can cause poor shutoff and inconsistent spray patterns.
