DATA NOTES:
6” deep units are only available with metal contour stabilizers.
MERV 9 models, 12” and 6” have a welded wire grid as media support backing.
** Recommended final resistance is 1.5” w.g. System design may dictate a lower change-out point.

Respective listed efficiencies are MERV per ASHRAE 52.2 and MERV-A per Appendix J of that Standard.
Maximum continuous operating temperature is 200° F (93° C), intermittent 220° F (104° C).
Listed UL 900 by Underwriters Laboratories.
Riga-Flo MERV 9, as noted below, includes a wire backing on the media.
Options:
Available with header for side-access or front access applica-
tions, as shown at right. See Product Sheet 1303PH.
Specifications
1.0 General
1.1 - Air filters shall be high-efficiency ASHRAE high lofted supported media
disposable type assembled in a compact and secure enclosing frame.
1.2 - Sizes shall be as noted on drawings or other supporting materials.
2.0 Construction
2.1 - Filter media shall be of microfine glass laminated to a reinforced back-
ing to form a uniform lofted media blanket.
2.2 - The media blanket shall be formed into uniform tapered radial pleats
and bonded to a stiffened backing that is bonded to the downstream side of
the media to preclude media oscillation.
2.3 - The media shall be mechanically and chemically bonded within the
frame to prevent air bypass.
2.4 - The enclosing frame shall be constructed of corrosion resistant gal-
vanized steel. The media pleat configuration shall be maintained by bridge
style plastic contour stabilizers. There shall be a minimum of four contour
stabilizers on the air entering side and four on the air exiting side.
3.0 Performance
3.1 - The filter shall have a Minimum Efficiency Reporting Value of (MERV
9, MERV 11, MERV 13, MERV 14) per ASHRAE Standard 52.2. It shall
have a MERV-A of (9, 11, 13, 14)* when tested under Appendix J of that
standard.
3.2 - Initial resistance to airflow shall not exceed (0.20”, 0.35”, 0.50”,
0.65”)* w.g. at an airflow of 500 fpm for filters having a nominal depth of
12”. For a 6” model initial resistance to airflow shall not exceed (0.08”,
0.25”, 0.50”, 0.60”)* w.g. at an airflow of 300 fpm.
3.3 - The filter shall be capable of withstanding 10” w.g. without failure of
the media pack.
3.4 - Manufacturer shall provide evidence of facility certification to ISO
9001:2000.
3.5 - Filter shall be listed UL 900 by Underwriters Laboratories.
Supporting Data - Provide product test reports for each listed efficiency
including all details as prescribed in ASHRAE Standard 52.2-2007 includ-
ing Appendix J.
Product shall be Camfil Farr Riga-Flo or approved equal.
