MERV 8 Extended Surface Pleated Filters

Pleated media panel filter

•Ecologically advanced filtration medium made entirely from recycled materials.

•Media maximizing V-pleat design

•Expanded metal grid prevents media flutter while in operation

•Diagonal and horizontal support members pro- vide frame strength

•Filter media pack is sealed to eliminate air bypass

•Average efficiency is 30-35% per ASHRAE 52.1-92

•Average arrestance is 93%•

•MERV Rating 8 per ASHRAE 52.2-99

The new MERV 8 Pre Pleat 40 filter features a filter- ing medium that is more efficient AND ecologically friendly. Made entirely from recycled materials, this medium achieves MERV 8 efficiency with low resist- ance to airflow. It is also unaffected by high humidity and is hydrophobic (non-moisture absorbing.)

Pre Pleat 40 filters can upgrade existing flat panels as well as MERV 6 & 7 pleated filters currently being used with little increase in resistance. All PrePleat 40 filters are 30-35% efficient by ASHRAE 52.1-92 and MERV 8 per ASHRAE 52.2-99.

These filters are suitable for variable air volume sys- tems. Operating face velocity ranges are from 0 to 500 fpm for 1 in. and 2 in. filters, and from 0 to 625 fpm for 4 in. filters. Pre Pleat 40 filters are UL 900 Class 2 listed but are available with UL Class 1 listing.
