However, because of the "rigors" of shipping, ENVIRCO encourages its re-test after installation. ENVIRCO recommends that the customer contact an independent organization, with technicians trained and experienced in performance evaluation and maintenance of clean air equipment. Some of the testing procedures performed on the MAC 10 VE5 include PSL challenge of HEPA/ULPA filters to assure specified performance, along with air velocity measurement and adjustment tests. No DOP is used on MAC 10 Filters, unless requested. Recommended Testing All units that are airflow tested at Envirco are tested using a Shortridge Airdata Multimeter 800 series with a Velgrid head. The recommended method of reading is to place one corner of the Velgrid head 1-1/4" from the corner of the filter face and then take four reading evenly spaced along the four foot side, then repeat these reads for the other long side. This gives a total of eight reading to test the unit. All advertised data is based on using the Velgrid with eight readings (128 velocity points). Envirco recognized using eight reading during a cleanroom start-up may be time consuming and recommends using three Velgrid readings taken on a diagonal, as shown below.
