Characteristics
¡òMembrane stack consists of reinforced-type PVDF membrane
¡òPossess superior properties of heat- resistance and chemical-resistance
¡òIt can ensure wet air and other gas pass through smoothly, even when the differential pressure is very low. But the water liquid can¡¯t permeate
¡òIt holds the opposite capability against hydrophilic membrane

Applicable Fields:Filtration for air, gas and hydrophobic chemicals
¡òPTFE membrane possesses extremely strong chemical compatibility
¡òIt can filter most of the organic solvents and strong corrosive chemicals
¡òIf hydrophobic PTFE membrane is used to filter hydrophilic liquid, please soak the membrane into ethanol or isopropanol liquor beforehand so the hydrophilic liquid
can be filtered
