Practical Guide
Process Reliability with the SATAjet X 5500 Digital: Air, Pressure, Reproducibility
This guide focuses on the “invisible” levers: air quality, stable inlet pressures, reproducible settings, and easy-to-maintain digital module handling – so your finish stays consistent.
Process Focus: What “Constant” Really Means
Pressure Control
Gun Inlet Matters
Read digitally, adjust under trigger pull
Air Quality
Dry & Low-Oil
Maintain filters/separators, avoid condensate
Reproducibility
Document
Record nozzle, cap, pressure, distance, temperature
Setup Checklist Before Application
- Compressed Air Line: Check water/oil separators, drain condensate, monitor filter level
- Hose & Swivel Joint: No kinks, suitable length/inner Ø; use swivel for steady hand guidance
- RPS/Cup: Clean, properly locked; material strained and prepared per datasheet
- Nozzle System (X): I or O geometry matched to material flow and desired pattern
- Digital Display: Function check; battery level, clearly readable display
- Test Panel: Prepare test plate to validate spray pattern in advance
Pro Tip: Always set pressure under load (trigger pulled). This way, the digital display reflects the actual gun inlet – the basis for reproducible results.
Reference Values for Stability (Starting Points)
Fine-tuning follows the paint manufacturer’s datasheet and booth conditions. Values are guidelines:
- RP – Clearcoat/Topcoat: Gun inlet approx. 2.0 bar; nozzle 1.3–1.4; constant distance
- HVLP – Basecoat: Inlet pressures on the lower side; nozzle often 1.3; steadier stroke guidance
- Spray Distance: Keep in moderate range, overlap passes evenly (e.g. 60%)
- Documentation: Note nozzle, cap, pressure, temperature, material batch
Note: Variations depend on product and booth. Always validate on test panel.
Quality Assurance in 6 Steps
- Check Air: Filters/separators OK, no condensate; record booth temperature
- Prepare Gun: Suitable X nozzle (I/O), clean air cap, properly locked cup
- Set Pressure: Under load on digital gauge; record setpoint
- Spray Test Panel: Evaluate pattern, mist, texture; fine-tune pressure/flow if needed
- Application: Constant distance/angle; even coverage; steady hand guidance
- Review: Inspect finish & particles, save parameters for repeatability
Air-Side Issues – Quick Fixes
Pressure Drops Under Load
- Check line path (couplings/hose/inner Ø)
- Check compressor/regulator throughput
- Re-adjust at gun inlet under load
Water/Oil in System
- Service separators/filters, drain condensate
- Replace filter stages in time
- Flush and dry lines
Unstable Spray Pattern
- Clean/mount air cap/nozzle correctly
- Stabilize distance/angle
- Select suitable X nozzle geometry
Unclear Display
- Check digital display for battery/readability
- Re-adjust under trigger pull
- Protect display from moisture/impact
Maintenance & Digital Module
- Flush after use, clean nozzle/air cap/needle – no aggressive brushes
- Check and replace seals/wear parts periodically
- Keep digital display dry, protect from shocks; monitor battery status
- Lightly oil threads, store gun dry
- Use only approved cleaning agents
Configure for Consistent Results
We provide advice on air line, nozzle geometry & pressure control.
All settings are reference values and depend on material/datasheet.
