Would You know when the integrity test is required ? In my compressed air systems there are 0.2um filters before point in use. And now: we have one manufacturer’s device to making the integrity test of its filters. Another manufacturer can send to us his engineer for making the test. But third manufacturer needs to receive the filter, send it to another country to make the integrity test, then resend it to us. When I asked about possibility of destroying the membrane during transport they said the filter is packing carefully etc.
My question is: Do we need make the integrity test of new filter cardridge ? One manufacture says the test needs to be done because there is a little possibility of destroy the membrane during transport (in our HVAC systems we have the HEPA filters and we make the integrity tests after every exchange).
And how often it has to be making ? (we use the CA for drying the equipment, automation but of course the air has a contact with product in some machines).
Thanks in advance
