1. It is mechanical-electrical-pneumatic integration, with structure compact and facile to be operated, which can automatically perform a duty cycle thanks to its high automatic degree.

2. Can inspect two pieces of filters at the same time to improve the efficiency.

3. The threaded connections and the sealing rings for the test stand can be changed for the different types of the spin-on filter in order to inspect the sealing performance for the different types of the oil and fuel filters. The threaded connection will be easy and quick to be changed.

4. Control the testing duration through adjusting the time relay to obtain high productive efficiency.

5. Adjust the air pressure and upper or lower stroke when needed, which make the test direct viewing and accurate.
