Product Features
AAF Flanders PREpleat LPD SC filter is a high strength supported MERV eight pleated filter which pair low initial resistance with high dust holding capacity which combine to provide an extended life cycle and energy efficient performance.
Applications: Commercial Building, Industrial, Hospitality, Pharmaceutical, School, Universities, Agriculture and Tobacco Applications
Lowest initial resistance MERV eight pleated filter
Higher dust holding capacity than competitive high capacity filter deliver longer life and more energy efficient performance
Superior strength due to two piece die cut frame with diagonal and horizonal support member and wire backed media
Expanded metal grid maintain pleat shape during operation for full media utilization and high dust holding capacity
Filter media bonded to the frame at all points of contact to eliminate dirty air bypass
100% synthetic non-woven, proprietary media
Engineered with a gradient density composition that achieve a MERV eight rating using the mechanical method of particle capture
Media does not rely on an electrostatic charge to capture particulate and will only increase in efficiency over time
Expanded metal is continuously laminated on the air leaving side to provide pleat stability during operation
Pleat shape is maintained, allowing full media utilization and maximizing dust holding capacity
V-pleat design aids in pressure drop while reducing energy cost
Design allow for maximum airflow and dust holding capacity during the life of the filter
Heavy duty, two piece, moisture-resistant frame include diagonal and horizontal support member bonded to the media on the air entering and exiting side for unsurpassed frame strength
Interlocking corner and positive media to frame seal reduce the possibility of air bypass
