Precision Pak XDH

Semi-Rigid, High Dust Holding Capacity Extended Surface Bag Filter

Bulletin PB1102-1206

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.
