Premium Construction and Performance

Designed to meet the demands of the toughest applications, the MEGApleat M11 filter offers a totally unitized, die-cut box, beverage board frame with double thickness in the perimeter wall. The MEGApleat M11 filter is extremely strong and durable under normal operating conditions. The MEGApleat M11 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 MEGApleat M11 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′′ MEGApleat M11 filter, a pleat stabilizer is added to maintain proper spacing and improve dust holding, resulting in longer service life.

High Efficiency Media Captures More Fine Particulate

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. The MEGApleat M11 filter meets and exceeds these requirements. Electrostatically charged media has a high initial efficiency and is particularly effective in capturing finer particulate.

Applications

The MEGApleat M11 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.
