Background
In the rapidly growing new energy battery manufacturing sector, cleanroom air quality plays a critical role in ensuring product consistency and safety.
The customer operates a battery production facility where a wide variety of air filters are used, ranging from F6 to H14, incluindo non-standard large-size filters. For example, their F9 filters reach lengths up to 1.2 meters, which exceeds the capabilities of most conventional test systems.
No entanto, existing testing solutions in the market present clear limitations:
- Systems based on ISO 16890 e ASHRAE 52.2
→ Suitable for general ventilation filters
→ Cannot test high-efficiency (HEPA) filters - Systems based on ISO 29463
→ Designed for HEPA/ULPA filters
→ Minimum efficiency starts from E10, not suitable for F-class filters
This created a key challenge:
“Do we need to invest in two separate testing systems?”
For growing manufacturers, this raises several concerns:
- High initial investment
- Increased maintenance costs
- Higher operational workload
- Difficulty justifying ROI with unstable product demand
Solution
To address this challenge, SCPUR engineers developed a customized solution based on the:
👉 SC-L8023 Automatic Scanning Test System
Through extensive testing and optimization, both hardware and software were upgraded to expand the system’s capability.
Key Improvements:
- ✅ Extended efficiency testing range: F9 → H14
- ✅ Increased airflow capacity by 20%
- ✅ Supported large-size filters up to:
1220 × 1220 × 400 milímetros - ✅ Enabled accurate testing for 1.2m F9 filters
- ✅ Added intelligent reminders for:
- Pre-filter replacement
- HEPA filter maintenance
This allows a single system to cover both medium-efficiency and high-efficiency filters, significantly reducing investment cost.
Field Application
The upgraded system has now been successfully installed at the customer’s facility.
- ✔ Passed on-site acceptance testing
- ✔ Stable operation in production environment
- ✔ Improved testing efficiency and workflow
The customer can now perform full-range filter testing (F6–H14) with one integrated solution.
Conclusão
For manufacturers in the new energy industry, balancing performance, flexibility, and investment cost is critical.
This case demonstrates that with the right engineering approach, it is possible to:
- Eliminate the need for multiple testing systems
- Handle non-standard large-size filters
- Achieve reliable and accurate results
👉 A practical and efficient solution aligned with SCPUR’s philosophy:
“Providing practical and efficient quality control solutions for filter enterprises.”
