Variable air volume systems, turbulent airflow, or high humidity applications where conventional filters fail, are good choices for upgrading to PrecisionCell II's in metal frame configurations. PrecisionCell II 4 inch deep in M and MSH designs are designed to be operated at 500 FPM. Both M and MSH Model PrecisionCell II's are offered in all standard sizes. Special sizes are not available. All PrecisionCell II models utilize state of the art minipleat technology which uses media separators made from thermoplastic glue beads to allow precision spacing between the moisture-resistant microfine fiberglass media. The adjacent polymer bead separators cure into durable, hard strips separating the media folds thereby creating a rigid pack assembly which maintains excellent pleat spacing continuity over the life of the filter. Both PrecisionCell II metal-framed models are bonded and sealed into a corrosion-resistant, metal frame with an expanded metal face grille on the downstream side to prevent media pack oscillation or blowout. Both metal framed models are the ideal choice where HVAC Systems pull in 100% humid outside air such as Hospitals. Important Features • High Efficiency Filtration in minimal, space-saving design. • This unique shallow-depth pack compacts up to 2 times the media area found in conventional 12 inch deep filters. • 3-to-1 ratio in shipping, storage, handling and disposal costs over conventional 12" deep cells • Excellent choice for upgrading older systems at a fraction of the cost.
