A HEPA filter manufacturer in Spain recently faced challenges in maintaining consistent product quality while controlling testing costs. The client was producing H13 and higher-grade filters and needed an automated scanning system for factory quality inspection.
According to EN 1822, filters rated H13 and above require testing at MPPS (Most Penetrating Particle Size), which typically involves particle counters capable of detecting particles down to 0.1 μm. However, such high-precision particle counters are usually manufactured in the U.S. or Germany and come with a high cost, creating a significant investment burden.
Understanding the Client’s Needs
The client’s primary goals were:
- Perform reliable leak detection for batch H13 filters
- Ensure compliance with EN 1822
- Reduce equipment investment cost
- Improve testing efficiency for factory use
SCPUR’s Engineering Solution
After analyzing the client’s application, the engineering team at SCPUR identified a practical and cost-effective approach.
While MPPS testing often requires a 0.1 μm particle counter, in real production environments, many manufacturers use 0.3 μm particle counters for H13 filter leak detection while still meeting the practical requirements of EN 1822.
Based on this, SCPUR proposed a cost-optimized configuration:
- SC-L8023 HEPA filter leak test bench
- Equipped with a 0.3 μm particle counter
- Reliable leak detection performance
- Significantly reduced equipment cost
Validation Through Real Testing
To verify the solution, the client sent H13 filter samples to SCPUR.
Using the SC-L8023 scanning system, a full surface scanning test was conducted. The results confirmed:
- Accurate detection of local leaks
- Stable and repeatable performance
- Compliance with practical EN 1822 leak detection requirements
The client confirmed that the solution met their production needs without requiring a high-cost imported 0.1 μm particle counter.
Results and Benefits
By adopting SCPUR’s solution, the client achieved:
- ✅ Significant cost savings
- ✅ Reliable HEPA filter leak detection
- ✅ Improved production testing efficiency
- ✅ Compliance with EN 1822 requirements
Conclusion
This case demonstrates that optimized system configuration can effectively balance performance and cost.
With its flexible design and reliable performance, the SCPUR SC-L8023 HEPA filter leak test bench provides an efficient and economical solution for HEPA filter manufacturers.
SCPUR remains committed to delivering cost-effective testing solutions that help customers ensure product quality while reducing investment costs.
