Valairdata 4 is the next generation of fully automated aerosol challenge integrity test unit, designed to test the integrity of sterile gas filters quickly and easily.

The Valairdata 4 aerosol challenge test is fully correlated to aerololized B. diminuta, B subtilis and Enterobacteria phage MS2 challenges and is a recommended test methodology in the PDA’s “Sterilizing Filtration of Gas – Technical Report #40”.

The unit utilizes Parker’s 50 years of experience in the provision of world leading sterile gas solutions by further improving the usability and sensitivity of the test process and offers significant savings in operator time.
