The Palltronic® AquaWIT system offers major benefits for integrity testing of hydrophobic gas filters. All stages of the water intrusion test can now be performed fully automatically on gas filters and on line. The operator simply connects the Palltronic AquaWIT unit to the filter system, inputs test parameters on the easy to use touchscreen and starts the test sequence. The filling, testing, draining and drying is performed without further operator involvement and a detailed test result is saved and printed.

With Pall direct flow measurement technology and a "hydraulic bridge" link to the test filter, accurate and reproducible results are ensured even during changes in environmental temperature. "It is expected that there be some program for integrity testing this (vent) filter to assure that it is intact." "There are methods for integrity testing of vent filters in place."
