PROTOS 90 Spare Parts Guide: Upgrading from PROTOS 70, Maintenance, and Compatibility
The Hauni PROTOS 90 represents the next generation of cigarette makers beyond the widely-installed PROTOS 70, offering 8,000+ cpm output versus the PROTOS 70's 7,000 cpm. As PROTOS 70 units age and production demands increase, many facilities are evaluating or already implementing the upgrade to PROTOS 90. Understanding the spare parts landscape for both machines is essential for a smooth transition.
PROTOS 70 vs PROTOS 90: Key Differences
| Parameter | PROTOS 70 | PROTOS 90 |
|---|---|---|
| Output speed | 7,000 cpm | 8,000+ cpm |
| Control system | PLC-based | Advanced servo control |
| Rod forming | Similar garniture design | Enhanced cooling section |
| Filter attachment | MAX or similar | Integrated or MAX S/90 |
| Installed base | 1,000-1,500 units | Growing, replacing 70s |
Part Compatibility: PROTOS 70 vs 90
- Interchangeable (same design): Cutting knives (standard 22mm round), garniture tapes (same width specification), suction belts (common hole patterns), heater bands (standard sizes)
- Partially compatible: Drum rollers (diameter increased on 90 for higher speed), tongue and horn (similar geometry, different material treatment), guide rails (same profile, different wear coating)
- Machine-specific (not interchangeable): Control modules (servo vs PLC), motor drive units, sensor arrays (higher density on 90), seam sealing drum assembly
Critical Spare Parts for PROTOS 90
1. Rod Formation
- Garniture tongue and horn: The most wear-critical assembly. PROTOS 90 runs at higher speed, increasing wear rate by approximately 15-20% vs PROTOS 70. Regular inspection every 2 weeks recommended.
- Suction belt assemblies: Higher belt speed increases wear. Use reinforced belts designed for 8,000+ cpm operation.
- Cutting knife drum: Precision-balanced for higher RPM. Bearing replacement interval: 12 months.
2. Tobacco Feed Section
- Feed roller assemblies: High-traction surface treatment required for consistent tobacco curtain at higher speed.
- Hopper components: Vibrating mechanism tuned for higher throughput. Spring fatigue is more common than on PROTOS 70.
- Tobacco distribution rollers: Requires tighter clearance tolerances than PROTOS 70.
3. Sealing and Quality
- Heater control modules: Higher speed requires more responsive temperature control. Thermocouple response time is critical.
- Optical inspection sensors: PROTOS 90 has a more comprehensive rejection system. Sensor cleaning every shift is essential.
- Seam sealing drum: Higher-temperature operation than PROTOS 70. Check thermocouple calibration monthly.
Upgrade Planning Considerations
- When upgrading from PROTOS 70 to 90, plan for a minimum 60-90 day spare parts inventory overlap period
- Common consumables (knives, tapes, belts) can be shared across both machines during transition
- Machine-specific parts (tongue, drum assemblies, control modules) will need separate inventory for each generation
- Consider upgrading the filter attachment simultaneously — MAX S/90 has different interface specs than MAX S/70
