LIMITED WARRANTY: Unless otherwise expressly
stated in ENVIRCO’s published specifications for the

paid by Buyer for the Goods which gave rise to the breach.
Any repair, replacement or re-performance by ENVIRCO
hereunder shall not extend the applicable Warranty Period.
The parties shall mutually agree on the specifications of
any test to determine the presence of a defect. Unless
otherwise agreed upon by ENVIRCO in writing, Buyer shall
bear the costs of access, de-installation, re-installation

Testing
Each MAC 10 LEAC2 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 your 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, take four readings evenly spaced along the
four foot side, then repeat these reads three additional
times. This gives a total of eight readings to test the unit.
All advertised data is based on using the Velgrid with eight
readings (128 velocity points). ENVIRCO recognizes that
using eight readings during a cleanroom start-up may be
time-consuming and recommends that using four Velgrid
readings taken on each 2x2 filter section will approximate
the same as eight readings.
