Flanders Semi Rigid Figh Dust Holding C apacity Extended Surface Bag Filter Pak XDH Specification Sheet

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 65%, 85% and 95% per
ASHRAE Standard 52.1 and 52.2 test methods.
Operating face velocities up to 625 fpm are avail-
able for all models.

Ideal for VAV

Precision Pak XDH filters in depths up to 22" are-
semi-rigid and thus ideally suited for variable air
volume systems. Precision Pak XDH filters are UL
900 Class 2 listed.

Dual Phase Media

Precision Pak XDH bag filters use dual phase
polyolefin synthetic media. The media is thermal-
ly bonded without binders and consists of non-
woven continuous hydrophobic (water repellent)
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) capacity. 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
approximately 150% more dust by weight than the
others when run to the same final resistance. This
characteristic makes it an excellent choice for very
dusty areas and for those systems where long
service life and reduced maintenance are key con-
cerns.
