DOP or PAO Test in HEPA Filter

DOP/PAO testing is a very quick process that tests the integrity of the HEPA (High Efficiency Particulate Air) filter using DOP or PAO solutions in their operational conditions.

These solutions generate a gas type smoke and then generate gas particles that will be greater than .03 microns. The test will certify the HEPA filter is fully functioning and there is no leakage or damage

DOP (Dispersed Oil Particulate) is a dispersed aerosol used to test the integrity of HEPA filters.
PAO (Poly Alpha Olefin) is a non-carcinogen liquid which is a most common replacement for DOP.

DOP test

Any equipment that has a HEPA filter should be tested every time the equipment is moved or going to be used on a new project For the best results testing should be done on-site to ensure that the units have not been damaged due to transportation or daily activities at the work site.
