Equally once the unit is installed in the user s production site the test should be performed promptly to verify the integrity of the filter as well as the installation.
Clean room hepa filter testing.
Di octyl phthalate dop is a chemical aerosol for cleanroom filter testing.
Testing in accordance with en1822 is normally accomplished with an aerosol probe.
The probe is moved over the entire surface of the filter.
Thus if we test the hepa filter to determine if it has passed we can guarantee that the air we are introducing into the cleanroom is particulate free for the chosen filter quality.
When the hepa filter is tested in situ and it is leak free we can be sure that we are only introducing clean air into our facility.
Poly alpha olefin pao is a common substitute.
Testing your hepa filtration system testing per the accepted standard european norm en1822 2009 is used to certify filtration performance.
Hepa filter testing cleanroom certification.
Failure or incorrect application of the hepa filter will lead to a degradation of the clean air.
Hepa filter integrity testers hepa filter integrity tests are performed to determine if there are leaks in the high efficiency particulate arrestance hepa filters which remove contaminants and establish a specified level of particles is present in the clean room.
The installed hepa filters require regular testing to ensure they remain leak free.
The hepa filter integrity test is typically performed on cleanroom supply air hepa filters using a photometer to scan the filter surface for pinhole leaks that could allow the transmission of contaminant particles that would be unacceptable in a critical application.
However di octyl phthalate is now considered a carcinogen and no longer used.

You can trust cleanroom associates to get the job done right.
Jesus casas provides tips to ensure hepa filters are fit for purpose once installed in your facility.
