They may also be utilized where extreme velocity or turbulence have rendered other products to be ineffective. PrecisionCell GT filters are available in ASHRAE efficiencies of 60-65% and 90-95% in either single or double header versions. Features The PrecisionCell GT offers a high dust holding capacity for increased service life, eliminating costly downtime and maintenance associated with filter change out. The media is manufactured of a wet-laid, moisture resistant, dual layer micro-fine fiberglass with high tensile strength and long service life. The heavy gauge hemmed-edge corrugated aluminum separators offer increased pack rigidity with optimal pleat spacing. The heavy duty corrosion-resistant steel frame and expanded metal faceguards on both the air entering and air leaving sides protect the media pack. Retainer straps and faceguards on both sides prevent filter collapse and maintain rigidity in elevated resistance situations and blow back from turbine surges. Physical Data Frame: Heavy duty corrosion-resistant steel Media: Dual layer wet-laid micro-fine fiberglass, sealed with class 1 urethane Separators: Hemmed-edge corrugated aluminum Headers: 13/16” wide corrosion resistant steel Faceguards: Galvanized steel expanded Gridstraps: Aluminized steel ”T” strap downstream and horizontal strap upstream Flanders PrecisionA ire - Foremost in Air Filtration Toll Free: 1-800-637-2803 Nominal Depth (inch) Efficiency Nominal Size HxWxD (inch) 250 fpm 375 fpm 500 fpm 625 fpm Media Area (sq.ft.)
