PD represents clean pressure drop in inches w.g. Recommended final pressure drop for all models is 1.5 inch w.g. 2. Actual filter face size of 24” x 24” and 24” x 12” is 5/8” undercut on height and width. All other sizes are 1/2” undercut on height and width. Actual filter depth is 3-3/4” 3. Efficiency is average and is based on ASHRAE Standard 52.1 and 52.2 test methods. 4. Performance tolerances conform to Section 7.4 of ARI Standard 850. 5. Perfmormance values shown in this publication may be averages or estimates intended to generally represent product styles. Always contact factory for latest actual test data on specific Flanders Precisionaire models. Prefilters Prefilters are always a wise choice for the protection of minipleat filters no matter what the efficiency or brand. The closely-spaced pleats are subject to face-loading (bridging) by lint and coarse particles, thus reducing their usual long life. A minimum 2530% ASHRAE efficiency pleated panel filter such as the Flanders Precisionaire Prepleat 40 is recommended. Save In-Line Space Compare the airway lengths of 22” PrecisionPak bag filters and 12” Rigid-Air filter to a 4” PrecisionCell filter when they are installed with 2” prefilters. VAV Systems Filter banks should be sized so that the face velocity at maximum design conditions is 625 fpm or less. PrecisionCell II filters may be applied at any capacity between 0 and 625 fpm. Operating a filter bank at reduced flow will greatly increase expected filter life. Save Storage Space and Shipping Costs Using the 24” x 24” size as an example, a carton of four PrecisionCell II 4” filters has a volume of 5.3 cubic feet and a weight of 26 lbs. Compare this to four 12” deep rigid separator-type filters packed in four cartons with a total volume of 16 cubic feet and total weight of 80 lbs. Flanders PrecisionAire - Foremost in Air Filtration Toll Free: 1-800-637-2803 Application Guidelines PrecisionCell II filters should be selected for new installations with 24” H x 24” W and 24” H x 12” W face sizes. These are the most widely used and stocked sizes. This allows for 12” increments in height and width of the filter bank and insures that replacement cartridges will be readily available. PrecisionCell II filters should be installed with the pleats vertical wherever possible. It is permissible to install 24” H x 12” W face size filters with pleats horizontal if necessary to meet the size requirements of the filter bank. HEPA Prefilters PrecisionCell II filters are ideal as prefilters for Alpha Cell HEPA filters. Their light weight and 4” depth make them an excellent choice PrecisionCell II M and MSH Component Chart 88655. 04 20 24 MSH D Efficiency Series 89655. - 90-95% 88655. - 80-85% 86655. - 60-65% Nominal Depth 04 - 3.75” Deep Nominal Width 20 - (19-3/8”) wide Nominal Height 24 - (23-3/8”) tall Frame Style MSH - Metal w-13/16” Single Header Gasket Location D - Downstream U - Upstream V - One Vertical Side for installation in the optional Prefilter Frame Assembly for the Alpha Cell HEPA Filter Holding Frame or in Surelock Side Access HEPA Housings. Specify the Surelock housing with an optional 4” wide prefilter track for the PrecisionCell II filters, in lieu of the 2” wide prefilter track for pleated panel filters. We recommend the selection of 80-85% PrecisionCell II filters as HEPA prefilters. 1.0General1.1 Medium and high efficiency extended surface filters shall be PrecisionCell II (M) (MHS) mini- pleat panel filters as manufactured by Flanders Precisionaire. 1.2 Filter sizes, efficiencies and capacities shall be as scheduled on the drawings. 1.3 Filters shall be UL 900 Class 2 listed. 2.0FilterConstruction2.1 The filter pack shall be constructed of water-laid microfine fiberglass media containing a water repellent binder formed into closely spaced pleats held in position by adhesive bead separators. 2.3 The filter pack shall be enclosed and sealed with- in a corrosion-resistant metal frame. 2.4 PrecisionCell II MSH filters shall have a single 13/16” diameter header on the air entering side. 3.0Performance3.1 Initial and final resistances shall not exceed the scheduled values. 3.2 Media area must equal or exceed that of the specified filter 3.3 The average efficiency shall be as determined by ASHRAE Standard 52.1 and 52.2 test methods. 3.4 The manufacturer shall guarantee performance as stated in the literature within tolerances as outlined in Section 7.4 of ARI Standard 850.
