General Information

• PES membrane fibers with 7 bores provide high mechanical strength (>10x that of single fibers) and chemical resistance.
• Inside-Out filtration eliminates the air scouring step and additional related equipment.
• Elements are filled with glycerin when new, as part of the fiber manufacturing and preservation process.
• Elements must be stored in a dry and normal ventilated location, away from any sources of heat, ignition, and direct sunlight in the original packing.
