STEP 3: Insert aerosol test fitting or adaptor (the aerosol injection port has a 3/8" NPT internal thread) into Aerosol Injection port.
NOTE: An adaptor/test fitting that is longer than 1.5" and/or wider than 1" will not fit.
STEP 4: Inject aerosol test agent and measure particulate counts according to local codes.
NOTE: Aerosol Sample port can be used to measure upstream particle counts. Refer to page 15 for static pressure port details.
STEP 5: Disconnect test equipment, and reinstall plugs in the static pressure (if applicable) and aerosol injection ports. Reinstall
diffuser face (if applicable).
If the safety cables were also disconnected when removing the face, they must be reattached. When reinstalling the face, care
should be taken to tuck safety cables in place without damaging the filter.
NOTE: Airflow and aerosol challenge concentration should be kept uniform during the test. Static pressure and concentration may
be sampled through the static pressure port during the test, if required, to verify flow and concentration.
