AeroPleat IV
1.0	General
1.1	Air filters shall be medium efficiency ASHRAE panel filter consisting of a blended polyester media, a welded wire grid, and a 24 point high wet strength coated 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 blended polyester media, lofted to a uniform depth of 0.15”, and formed into a uniform radial pleat
2.2	A welded wire grid, spot-welded on centers and treated for corrosion resistance, shall be bonded to the downstream side of the media to maintain the radial pleat and prevent media oscillation. 
2.3	An enclosing frame, of a 24 point high wet-strength beverage board that is bonded to the media shall provide a rigid and durable enclosure.
2.4	Filters shall be made into high capacity pleat densities of 16 pleats per linear foot, 15 and 11 for 1”, 2” and 4” depths respectively.
3.0	Performance
3.1	The filter shall have a Minimum Efficiency Reporting Value of MERV 8 when evaluated under ASHRAE Standard 52.2. 
3.2	Initial resistance to airflow shall not exceed 0.22”, 0.27” or 0.21” w.g. at an airflow of 350, 500 or 500 fpm on 1”, 2” or 4” deep models respectively. 
3.3	The filter shall be listed by Underwriters Laboratories as UL Class 900
3.4	Recommended filter change out resistance is 1.0 w.g.
3.5	Manufacturer shall provide evidence of facility certification to ISO 9001:2015
