Flanders' Pre-Pleat 40 LPD achieves the highest dust holding capacity and the lowest pressure drop in the industry. These filters are UL 900-certified—100-percent synthetic, nonwoven, proprietary media that can be recycled. Newly designed expanded metal is continuously laminated on the air leaving side to provide pleat stability while eliminating flutter during operation. Heavy-duty, two-piece, moisture-resistant frame includes diagonal and horizontal support members bonded to the media on the air-entering and air-exiting sides for unsurpassed frame strength. Interlocking corners and a positive media-to-frame seal reduce the possibility of air bypass.
- Economically and environmentally friendly frame has a one-piece design
