SprayTech part 0276452 is an Air Cap #3 used to direct atomizing air across the fluid nozzle for proper spray pattern development. When the air cap becomes worn, damaged, or clogged, finish quality degrades and pattern distortion occurs. This replacement air cap restores proper airflow characteristics and consistent pattern quality on compatible SprayTech units.

The SprayTech 0276452 Air Cap #3 is a precision-engineered component that directs and shapes atomizing air as it exits the spray gun. On the SprayTech HVLP Maxum II system, this air cap works in conjunction with the fluid nozzle and air nozzle to produce a consistent, well-defined spray pattern. The air cap contains strategically placed horn holes and center orifices that control air velocity, pattern width, and droplet size. A damaged, worn, or incorrectly installed air cap can produce irregular patterns including crescent shapes, split patterns, heavy centers, or excessive overspray. The #3 designation indicates specific air flow characteristics optimized for medium-viscosity coatings including lacquers, stains, sealers, and polyurethanes on the HVLP Maxum II platform. Over time, normal use can cause air cap orifices to wear, altering air velocity and pattern symmetry. Dried material buildup inside the cap obstructs airflow, leading to pattern distortion and reduced transfer efficiency. Physical damage from drops or impacts can bend air horns or crack the cap body. Replacing the air cap restores original spray characteristics and finish quality. Regular inspection of the air cap for wear, damage, or contamination should be part of routine maintenance. When replacing, ensure the cap seats properly against the air nozzle and aligns correctly with the fluid tip. This genuine SprayTech replacement part meets original equipment specifications for fit, performance, and pattern quality. Users should verify compatibility with their specific Maxum II revision before installation.
| Pattern shaping | Directs air through horn holes to create flat fan pattern |
|---|---|
| Atomization support | Center orifices break fluid into fine droplets for smooth finish |
| Air flow regulation | Controls volume and velocity of atomizing air across fluid tip |
| Pattern distortion | Crescent, hooked, or split patterns that cannot be adjusted out |
|---|---|
| Poor fan uniformity | Heavy center, light edges, or uneven material distribution |
| Physical damage | Bent air horns, cracks, nicks, or deformed orifices |
| Orifice wear | Enlarged or eroded air passages from extended use |
SprayTech part 0276452 is compatible with the following SprayTech HVLP spray system. Always confirm fitment using the correct parts diagram for your exact model and revision.

Pattern problems are often caused by more than one component. When servicing the air cap, these parts are commonly inspected at the same time.
The fluid tip works with the air cap to control material flow. Worn or damaged fluid nozzles cause pattern defects.
The air nozzle directs primary atomizing air. Mismatched or worn air nozzles affect cap performance.
A damaged or cross-threaded retaining ring prevents proper air cap alignment and seating.
