Overview
The SUNS Auto Filter Cartridge Integrity Tester is a dedicated, multi-station pressure decay-based integrity testing system engineered for rapid, non-destructive verification of water-tightness and structural integrity in automotive filter cartridges—including cabin air filters, oil filters, fuel filters, and engine air intake filters. Utilizing a calibrated pneumatic pressure decay methodology compliant with ISO 15198 and ASTM F2096 principles, the instrument quantifies minute leakage rates by monitoring pressure stabilization and decay profiles within sealed test chambers. Designed specifically for high-throughput quality control environments, the four-station architecture enables parallel evaluation of up to four filter cartridges per cycle—significantly reducing per-unit test time while maintaining measurement repeatability ≤ ±1.5% full scale under controlled ambient conditions (23 ± 2 °C, 50 ± 10% RH).
Key Features
- Four independent, pneumatically isolated test stations with individual pressure transducers (range: 0–1000 kPa, resolution: 0.1 kPa) and solenoid-controlled sealing manifolds.
- Automated test sequence execution: vacuum pre-conditioning, pressurization (N₂ or clean dry air), dwell stabilization, decay measurement, and pass/fail classification based on user-defined threshold limits.
- Integrated environmental monitoring: real-time logging of chamber temperature and relative humidity to support traceable test records per ISO/IEC 17025 requirements.
- Rugged aluminum alloy frame with IP54-rated enclosure; designed for integration into production line QC bays or laboratory-grade validation workflows.
- Touchscreen HMI with intuitive workflow navigation, multilingual UI (English, German, Chinese), and embedded audit trail functionality supporting GLP/GMP-aligned data governance.
Sample Compatibility & Compliance
The tester accommodates cylindrical and conical automotive filter cartridges with outer diameters ranging from 50 mm to 220 mm and lengths up to 350 mm. Customizable sealing fixtures (O-ring grooved adapters and clamping collars) ensure secure, leak-free interface across diverse OEM geometries—including pleated cellulose, synthetic nonwoven, and multi-layer composite media configurations. All hardware and software components comply with CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), and firmware supports configurable reporting formats aligned with internal quality standards (e.g., IATF 16949 clause 8.5.1.2) and regulatory expectations for automotive component release documentation.
Software & Data Management
The embedded test management software (v3.2+) provides role-based access control (operator, supervisor, administrator), electronic signature capability, and automated generation of PDF test reports containing raw pressure vs. time curves, calculated leakage rate (mL/min at specified test pressure), pass/fail status, operator ID, timestamp, and environmental metadata. Data export options include CSV (for SPC analysis in Minitab or JMP), XML (for MES integration), and encrypted SQLite database backups. Audit trails record all configuration changes, test executions, and user logins with immutable timestamps—fully compliant with FDA 21 CFR Part 11 requirements when deployed with network authentication and certificate-based login.
Applications
- Final inspection of assembled automotive filter cartridges prior to packaging and shipment.
- In-process validation during filter media splicing, end-cap bonding, and housing assembly operations.
- Supplier qualification audits requiring objective, quantitative evidence of seal integrity under simulated service pressures (e.g., 30–150 kPa).
- Root cause analysis of field returns attributed to moisture ingress, particulate bypass, or premature media delamination.
- Supporting PPAP submissions with documented process capability (Cpk ≥ 1.33) for leak rate specifications defined in customer-specific requirements (CSRs).
FAQ
What types of automotive filters can be tested with this instrument?
Cabin air filters, engine air filters, oil filters, fuel filters, and HVAC inline filters—provided they feature rigid or semi-rigid housings compatible with standard O-ring sealing interfaces.
Is calibration certification included with delivery?
Yes—each unit ships with a factory-issued NIST-traceable calibration certificate covering pressure transducers and temperature/humidity sensors, valid for 12 months from date of commissioning.
Can test parameters be customized per filter part number?
Yes—the software supports up to 255 saved test methods, each defining unique pressure setpoints, dwell times, decay durations, and acceptance thresholds mapped to specific part numbers or material families.
Does the system support integration with a central MES or QMS platform?
Yes—via Ethernet TCP/IP with Modbus TCP and RESTful API endpoints for bidirectional data exchange, including real-time test status, result upload, and remote method deployment.
What maintenance is required to ensure long-term measurement stability?
Quarterly verification using certified reference leaks (1×10⁻³–1×10⁻¹ mL/min); annual recalibration recommended; no consumables beyond standard O-rings and desiccant for air supply conditioning.
