95%
General
Precision Pak XDH high dust holding capacity
extended surface bag filters are designed for use in
most commercial or industrial HVAC systems
where medium to high efficiency filtration is
required. Precision Pak XDH filters are available in
micro-fine polyolefin synthetic media with average
efficiency ranges of 75%, 85% and 95% per
ASHRAE Standard 52.1 test methods. Operating
face velocities up to 625 fpm are available for all
models. Precision Pak XDH filters in depths of 12”
and 22” are suited for variable air volume systems.
Filters with greater depth are not recommended.
Precision Pak XDH filters are UL 900 Class 2 list-
ed.
Kimberly-Clark Media
Precision Pak XDH bag filters use Kimberly-Clark
brand polyolefin synthetic media. The media is
thermally bonded without binders and consists of
non-woven continuous hydrophobic (water repel-
lent) fibers that resist water and most chemicals. In
addition, the media is gradient density, dual stage
and electrostatically enhanced for extra high dust
holding (XDH) capability. Further, the media is
non-shedding and performs exceptionally well in
high velocity and turbulent applications.
Extra High Dust Holding
A typical XDH bag filter was tested for ASHRAE
synthetic dust holding capacity against similar fil-
ters with fiberglass and meltblown synthetic media.
Results showed that the XDH filter held approxi-
mately 110% more dust by weight than the others
when run to the same final resistance. This char-
acteristic makes it an excellent choice for very
dusty areas and for those systems where long
service life and reduced maintenance are key con-
cerns.
