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
Pre Pleat 40
MERV 8 Extended Surface Pleated Filters
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.
