SAGOLA 3300 GTO Air Cap Guide: HVLP, EPA & TECH Compared
The air cap is the heart of your SAGOLA 3300 GTO. It determines spray pattern, material transfer efficiency, and final results. Here you’ll learn which cap – HVLP, EPA, TECH, or EVO – is best suited for your application.
The right air cap makes the difference between a good and a perfect finish.
Direct Comparison of Air Caps
| Air Cap | Air Consumption | Inlet Pressure | Main Application |
|---|---|---|---|
| GTO HVLP | 360 l/min | max. 1.8 bar | Environmentally friendly spraying, high transfer rate (>65%) |
| 3300 EPA | 250 l/min | approx. 2 bar | All-round applications, good material efficiency |
| GTO TECH | 285 l/min | approx. 2 bar | Technical applications, precise spray pattern |
| GTO EVO | 255 l/min | approx. 2 bar | Energy-efficient spraying, reduced consumption |
| 64S / 62S | 310 / 270 l/min | approx. 2 bar | Special industrial applications |
Note: Values are based on manufacturer specifications under optimal conditions. Actual consumption may vary depending on settings and environment.
HVLP: For Maximum Efficiency
Maximum material transfer (>65%), less overspray, ideal for environmentally conscious work and when material costs matter.
EPA: The All-Rounder
Balanced ratio of pressure and consumption. Perfect for daily work in workshops and industrial environments.
TECH/EVO: For Professionals
Precise control and optimized airflow. Ideal for demanding surfaces and technical coatings.

| Fan Width | Medium to wide | Variably adjustable | Even coverage without dry edges |
Climate Effects on Spray Results
Temperature and humidity significantly affect spray results. The SAGOLA manual provides specific adjustments for extreme conditions:
High Humidity (>70%) and Heat (>30°C)
- Increase nozzle size by 0.1–0.2 mm (e.g. from 1.2 to 1.4 mm)
- Set a more compact, rounder fan pattern (more material in the center)
- Reduce dynamic pressure by 0.2–0.5 bar
- Use manufacturer-recommended additives if necessary
Optimal Conditions (20–25°C, 50–65% RH)
- Use the standard fan pattern
- Stay within the recommended pressure range of the air cap
- Apply smooth, overlapping passes
Maintenance & Cleaning of Air Caps
- After each use: Remove the air cap and soak it in a suitable thinner
- Cleaning: Carefully clean with a soft brush (included) and compressed air
- NEVER: Insert hard or metallic objects into the nozzle holes
- Inspect: Check for deformation or damage to the air outlets
- Storage: Store clean and dry, protected from dust
Problems with the Air Cap?
- Uneven spray pattern: Check the cap for contamination and clean it
- Sideways deflection: One of the side air jets may be blocked
- Too much overspray: Pressure may be too high for the HVLP cap
- No clean fan: The central material nozzle may not match the fluid tip/needle
FAQ – Air Cap Specific
Can I use HVLP and EPA caps on the same spray gun?
Yes, the SAGOLA 3300 GTO is compatible with all common air caps. When switching, ensure correct pressure settings and matching needle sets.
What compressor capacity do I need for HVLP?
At 360 l/min consumption: At least a 4–5 HP compressor with sufficient tank volume. Rule of thumb: 1 HP ≈ 110 l/min. Plan reserves for simultaneous operation.
When should I replace the air cap?
In case of visible damage, deformation, or if a uniform spray pattern can no longer be achieved despite cleaning. Regular visual inspection is recommended.
Are original SAGOLA air caps important?
Absolutely! Only original parts guarantee perfect fit, optimal airflow, and the specified performance values. Non-brand products can damage both results and the spray gun.
Conclusion
Choosing the right air cap for your SAGOLA 3300 GTO is crucial for results and efficiency. HVLP stands out with high transfer efficiency and environmental friendliness, EPA is the reliable all-rounder, and TECH/EVO deliver professional precision. Adjust settings to material and climate, clean caps thoroughly, and use only original parts – this is how you get the maximum performance from your spray gun.
