Key Features & Benefits
1. High-Precision Pneumatic Leak Detection
The machine is equipped with ultra-sensitive pneumatic detection components. By applying controlled air pressure to the filter element, the system monitors pressure decay in real-time, allowing operators to identify microscopic leaks, pinholes, or seal defects that are invisible to the naked eye.
2. Fully Adjustable Testing Parameters
Through the PLC control interface, operators can easily adjust the target test pressure, pressure holding duration, and leakage sensitivity thresholds. This flexibility allows one machine to test a wide range of filter models with different quality standards.
3. User-Friendly Touchscreen PLC/HMI
The industrial touchscreen interface provides an intuitive setup process. Operators can quickly select pre-saved testing programs, monitor live pressure graphs, and receive clear “PASS” or “FAIL” indicators for rapid, high-throughput cycle testing.
4. Robust Construction for Continuous Testing
Designed for heavy-duty industrial environments, the tester features a rigid steel structural frame and premium pneumatic cylinders. The durable clamping fixtures are engineered to withstand millions of testing cycles with zero deformation, guaranteeing long-term mechanical stability.
Applications & Industrial Uses
This pneumatic leak testing machine is widely deployed in filtration factories for:
Automotive Filters: Verifying the seal integrity of spin-on engine oil filters and fuel filters.
Industrial Filtration: Testing heavy-duty hydraulic spin-on filter elements and separators.
Air Filtration Systems: Quality control for compressor spin-on air/oil separators.
End-of-Line QA: Performing mandatory 100% inspection routines before final product shipment.
