1.0 General
1.1 - Air filters shall be medium efficiency ASHRAE pleated panels
consisting of cotton and synthetic media, welded wire media support grid, and
beverage board enclosing frame.
1.2 - Sizes shall be noted on drawings or other supporting materials.
2.0 Construction
2.1 - Filter media shall be a cotton and synthetic blend, lofted to a
uniform depth of 0.15”, and formed into a uniform radial pleat.
2.2 - A welded wire grid, spot-welded on one-inch centers and treated for
corrosion resistance shall be bonded to the downstream side of the media to
maintain radial pleats and prevent media oscillation.
2.3 - An enclosing frame of no less than 28-point high wet-strength
beverage board shall provide a rigid and durable enclosure. The frame shall be
bonded to the media on all sides to prevent air bypass. Integral diagonal
support members on the air entering and air exiting side shall be bonded to the
apex of each pleat to maintain uniform pleat spacing in varying airflows.
3.0 Performance
3.1 - The filter shall have a Minimum Efficiency Reporting
Value of MERV 8 when evaluated under the guidelines of ASHRAE Standard 52.2-2007.
It shall also have a MERV-A of 8 when tested per Appendix J of the same
standard. The media shall maintain or increase in efficiency over the life of
the filter.
3.2 - Initial resistance to airflow shall not exceed 0.23”,
0.31” or 0.27” w.g. at an airflow of 350, 500 or 500 fpm on 1”, 2” or 4” deep models
respectively.
3.3 – The filter shall have an Energy Cost Index (ECI) value of five stars.
3.4 - The filter shall be classified by Underwriters
Laboratories as UL Class 2.
3.5 - Manufacturer shall provide evidence of facility
certification to ISO 9001:2000.
3.6 - Manufacturer shall
guarantee the integrity of the filter pack to 2.0” w.g.
Supporting Data - Provide product test report
including all details as prescribed in ASHRAE Standards 52.2, including
Appendix J.
Filter shall be Camfil Farr 30/30 or equal.
