*Reference values; dependent on material viscosity and pressure setting (cf. Table 1, SB-E-2-644).
Precision
Finest control of spray pattern and material flow through HVLP caps (0.7 bar at the nozzle).
Modularity
Quick change between lever and screw manifold for different production layouts.
Durability
All media-contacting parts made of stainless steel; resists solvents and abrasive materials.
Recommended Basic Settings (Reference Values)
- Atomization Pressure: 3.8–4.8 bar (HVLP)
- Material Pressure: 2.0–3.0 bar
- Nozzle: 0.5–1.0 mm for low-viscosity media
- Spray Distance: 150–200 mm
- Recommended Temperature: max. 40 °C ambient
Professional Workflow (5 Steps to the Perfect Finish)
- Fully open FAN and ATOM valves.
- Adjust fluid pressure via external regulator until the desired flow rate is achieved.
- Set air pressure to the starting value according to the table (e.g., 4 bar with CV-39-90HV).
- Perform a test spray – if the spray pattern is too fine, reduce air or slightly increase fluid pressure.
- Finally, turn off both media, release pressure, and clean the gun.
Troubleshooting (Excerpt)
- No spray pattern: Check air supply, is the fluid needle open?
- Sputters at start: Clean/replace dirty or damaged nozzle.
- Irregular jet: Clean air cap holes, check pressure.
- Sagging/Running: Reduce fluid pressure or adjust material viscosity.
Maintenance & Care
- Rinse with a suitable solvent after every use.
- Regularly check O-rings and seals for wear (Viton/HDPE).
- Lightly grease pistons and valves (Petroleum Jelly).
- Always replace nozzle and needle in pairs.
- When idle: Put on protective caps, release pressure.
FAQ – Frequently Asked Questions
- Can I use water-based media?
Yes, the AG362PU is approved for water- and solvent-based coatings (Zone 1/2 certified). - Which nozzle size is suitable for primers?
1.0 – 1.4 mm, depending on viscosity and air pressure. - How do I prevent uneven edges?
Maintain a constant spray distance and clean the air cap regularly. - When is a micrometer head useful?
For repeatable line coatings or automated cyclical processes. - How do I recognize wear?
Wear marks on the needle, poor spray patterns, increased material consumption.
Conclusion
The Binks AG362PU offers maximum control and efficiency for demanding coating processes. Its modular design, precise nozzle options, and excellent ease of maintenance make it the ideal solution for both series production and laboratory applications. Those who prioritize constant quality will find a tool here that perfectly combines technology and reliability.
