Resumen del manual
Operating face velocities up to 625 fpm are available for all models. Ideal for VAV Precision Pak XDH filters in depths up to 22” aresemi- 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 thermally bonded without binders and consists of nonwoven 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 filters 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 concerns.

How to Select a Precision Pak XDH Filter: • Determine the ASHRAE efficiency desired. • Determine the face velocity needed to fit the system. • Select the shortest depth possible with a pressure drop that is acceptable. • Select the most economical filter based on the number of pockets per 24” x 24” size.
