1.0 General
1.1 Terminal filter HEPA/ULPA Modules shall be
Pureflo Model PF as manufactured by Flanders
and shall be scan tested for leaks after assem-
bly.
1.2 Module sizes, filter pack depth, efficiencies and
capacities shall be as scheduled on the draw-
ings.
2.0 Module Construction
2.1 The module filter pack shall be constructed of
water-laid microfine fiberglass media containing
a water-repellent binder. The media shall be
formed into closely - spaced pleats held in posi-
tion by adhesive bead separators.
2.2 The filter pack shall be polyurethane-sealed into
aclear coat - anodized extruded aluminum
frame and rectangular tube section center
divider.
2.3 Module top/inlet collar shall be one-piece alu-
minum.
2.4 The protective face grille shall be 20 ga. expand-
ed steel finished in white powder coat paint.
2.5 Provide an airflow damper adjustable from the
room side and accessible through a port with a
removable plug located in the center divider.
2.6 Provide a separate port in the center divider that
is open to the inlet side of the filter for measure-
ment of static pressure and challenge aerosol
concentration. The port shall be fitted with a
removable plug.
3.0 Performance
3.1 Initial and final resistances shall not exceed the
scheduled values.
3.2 The airflow damper shall be capable of regulat-
ing the module face velocity from 70 fpm to 110
fpm.
3.3 Performance shall meet the requirements of
IEST RP - 1 for Type C or F filters.
