Filter Air Tightness Tester
The Filter Air Tightness Tester is designed to evaluate the sealing performance of filtration products, including air filters, fuel filters, and oil filters. The system applies pressure-based leak detection methods to identify leakage in filter assemblies, ensuring product integrity under operating conditions.
By monitoring pressure variation during testing, the equipment can detect leakage in critical areas such as filter housings, sealing rings, and joints. With a measurement accuracy of ±0.1% FS, it supports consistent and repeatable testing results, making it suitable for both laboratory verification and production line quality control.
