Binks AG 364 Airless Automatic Spray Gun – Setup, Tip Selection & Process Control
The Binks AG 364 is a modular airless automatic spray gun designed for industrial coating processes. This guide shows you the key technical specifications, recommended basic settings (guide values), typical fault patterns, and a field-tested workflow for stable, reproducible results.
Product Overview & Technical Data
| Feature | Value / Specification |
|---|---|
| Max. Fluid Inlet Pressure (P1) | up to 275 bar (4000 psi) |
| Cylinder Air Pressure (P2) | approx. 4 – 10 bar (guide value) |
| Fluid Connection | 1/4" NPS |
| Cylinder Connection | 1/8" NPS |
| Wetted Materials | Stainless Steel, Tungsten Carbide (Needle/Seat) |
| Weight (with Manifold) | approx. 820 g |
| ATEX | II 2 G X T6 – suitable for Zone 1/2 |
All values according to service documentation; pressure and process values are application-dependent guide values.
Variants: With or Without Fluid Recirculation
| Item | Description |
|---|---|
| AG364-0000-S | Without circulation (Non-Recirculation) |
| AG364-0000-T | With circulation (Recirculation Manifold) |
The recirculation variant is particularly suitable for temperature-sensitive or sedimenting media.
Maximum fluid pressure for high-performance airless atomization
Suitable for hazardous (explosive) areas
Fast gun replacement with fixed mounting
Recommended Basic Settings (Guide Values)
- Cylinder Air: approx. 4–10 bar
- Fluid Pressure: depending on tip size & viscosity (start at mid-range value)
- Tip Selection: matching desired coating thickness and spray pattern width
- Check Grounding: < 10⁶ Ohm contact resistance
The AG 364 operates without atomizing air – atomization and fan width are defined exclusively by fluid pressure and the spray tip.
Pro Workflow in 6 Steps
- Depressurize the system and ensure correct grounding.
- Mount the appropriate tip based on flow and fan requirements.
- Set the starting pressure and spray a test surface.
- Increase pressure step-by-step until a clean, uniform spray pattern is achieved.
- If flow is insufficient: select a larger tip.
- Finally, synchronize traverse speed and distance.
Typical Fault Patterns & Corrective Actions
- "Tails" in spray pattern: Increase pressure or check for a smaller tip.
- Heavy Center Pattern: Tip worn → replace.
- Streaks/Fingers: Tip partially blocked → clean/replace.
- Runs/Sags: Reduce fluid pressure or tip size.
Maintenance – 5 Key Points
- Fully release pressure before disassembly.
- Regularly check needle and seat for wear.
- Replace seals/O-rings in case of leakage.
- Flush fluid channels with a suitable solvent.
- Use original service kits.
FAQ about Binks AG 364
Is the AG 364 ATEX-compliant?
Yes, it is classified for Zones 1 and 2 (II 2 G X T6).
Does air affect atomization?
No, it is a pure airless spray gun.
Maximum fluid pressure?
Up to 275 bar according to specification.
Which media are suitable?
Water- and solvent-based coatings.
When should the tip be changed?
When the spray pattern is worn or fluid consumption increases.
Conclusion
The Binks AG 364 impresses with its modular design, high pressure resistance, and ATEX suitability. With the correctly chosen tip and adjusted pressure, it delivers reproducible airless results in demanding industrial processes.
