■ Testing
Each MAC 10 IQ filter unit is thoroughly tested at the factory
before shipment. 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.
HEPA filters (Type J) are tested to IEST-RP-00034. ULPA
filters are tested to (Type F) IEST-RP-00034. All filters are UL
900 recognized. Your filters may have special requirements,
please see original engineering specifications for you specific
project.
All units that are airflow tested at Envirco are tested using a
Shortridge Airdata Multimeter 870 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 three additional times. This gives a
total of 8 reading to test the unit. All advertised data is based
on using the Velgrid with 8 readings (128 velocity points).
Envirco recognized the using 8 reading during a cleanroom
start-up may be time consuming and recommends using
4 Velgrid readings taken on each 2x2 filter section will
approximate the same as 8 readings.
Additional independent testing on the Envirco Mac 10 IQ 2x4,
2x2, and 2x3, shows that using one-2x4 or two-2x2 hoods
simultaneously give airflow data (cfm) with 5 percent of a
duct traverse using 10 diameters of straight duct upstream
of the fan intake.
