MERV 11 Extended Surface Pleated Panel Filter • Premium performance and construction • Synthetic, electrostatically charged media with high dust holding capacity • Excellent as a final filter or prefilter • 1", 2" and 4" models • 4" filters are constructed with pleat stabilizers to ensure uniform spacing and increase rigidity Premium Construction and Performance High Efficiency Media Captures More Fine Particulate Designed to meet the demands of the toughest applications, the AmAir 1100 filter offers a totally unitized, die-cut box, beverage board frame with double thickness in the perimeter wall. The AmAir 1100 filter is extremely strong and durable under normal operating conditions. A MERV 11 rating requires a 65% to 80% efficiency on 1 – 3 micron particles and greater than 85% efficiency on 3 – 10 micron particles, when tested in accordance with ASHRAE Test Standard 52.2. AmAir 1100 filter meets and exceeds these requirements. Electrostatically charged media has a high initial efficiency and is particularly effective in capturing finer particulate. The AmAir 1100 filter also has a heavy duty, expanded metal pleat support grid laminated to the media pack to increase rigidity and help maintain proper spacing between pleats. Proper pleat spacing ensures maximum efficiency, low resistance, and high dust holding capacity. The media pack is bonded to the frame at all points of contact. This bonding prevents dirty air bypass and promotes even airflow through the media pack. The AmAir 1100 filter construction process results in a filter which is very stable, with no racking or vibration of the pleats under normal airflow. Pleat stability minimizes the chances of captured particulate shaking loose and re-entering the airstream. To support the increased pleat depth of the 4" AmAir 1100 filter, a pleat stabilizer is added to maintain proper spacing and improve dust holding, resulting in longer service life. Applications The AmAir 1100 filter will work in any application where an extended surface pleated panel filter is currently in service. It is particularly suited to applications where high initial efficiency and lower initial resistance is required.
