OPTI-PAC 1900 VAF
Opti-Pac VAF-19 is a proven low-fouling 3/4" vertical fluted film fill. The module design incorporates two alternating sheet configurations that optimize thermal performance without sacrificing low-fouling properties.
Opti-Pac VAF-19 media is manufactured from rigid PVC sheets for cooling tower heat-transfer applications. The media is fabricated from rigid PVC sheets conforming to CTI STD-136 that are solvent-welded for maximum strength and resistant to UV, rot, fungus and organic and inorganic solvents, acids and alkalis, and chemicals normally found in cooling tower waters.
Modules are fabricated in 12”, 24” and 48" depths, 12” and 24” widths, and in lengths up to 12’-0”. Standard sheet thicknesses available are 15 and 20 mil after forming. Weight per cubic foot is approximately 2.6 lbs/ft3 for 15-mil packs and 3.6 lbs/ft3 for 20-mil .Custom dimension modules are available upon request.
