PATON 225 Leakage Tester

The PATON 225 Leakage Tester allows engineers to test the leakage performance of a vehicles’ cabin. Designed to test larger vehicles than the PATON 150 whilst maintaining the simple control system and a portable design.



The PATON 225 Leakage Tester allows engineers to test the leakage performance of a vehicles’ cabin. It works by pressurizing, or depressurizing, the vehicles’ cabin to a specified test pressure, and measuring the air volume flow generated to produce a leakage rate, or ‘equivalent body hole size’ (EBHS). The PATON 225, like all our leakage testers, utilises three rapid change (push in – pull out) conical inlet nozzles, making this machine a primary measuring device. These precision machined nozzles, combined with a recently enhanced control POD gives an accuracy of +/-2% of reading.

The PATON 225 Leakage Tester can be used in a manual test mode where the engineer manually controls the fan speed, or it can be used in PID Closed Loop Control mode, and the machine will automatically adjust the fan speed during a test to maintain a set test pressure. Test data can be saved to an SD card and can be streamed over USB connection to a computer. The PATON 225 can generate up to a maximum 225l/s of airflow.
