The 0277092 Projector Set, #4A Complete is a spray-head component engineered for the SprayTech HVLP Maxum II. It works with the air cap and fluid components to guide coating material into a controlled, consistent spray pattern.
As projector components wear, spray quality can decline, leading to uneven fan patterns, poor atomization, or inconsistent coverage. Replacing the complete #4A projector set restores proper flow control and helps achieve a smooth, professional finish.
| Pattern shaping | Controls how material exits the spray head |
|---|---|
| Atomization support | Works with air components to help produce a uniform spray |
| Flow consistency | Helps maintain a stable, repeatable fan pattern |
| Uneven spray pattern | Fan shape becomes distorted or inconsistent |
|---|---|
| Visible wear | Erosion, scoring, or damage to projector surfaces |
| Poor finish quality | Spitting, streaking, or heavy droplets |
| Routine service | During spray-head rebuild or performance restoration |
Part 0277092 is compatible with the following SprayTech HVLP system. Always confirm correct size and orientation using the appropriate parts diagram.

Spray-head performance depends on several components working together.
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.
