Characteristics
Membrane stack consists of reinforced-type PVDF membrane
Possess superior properties of heat- resistance and chemical-resistance
It 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
It holds the opposite capability against hydrophilic membrane

Applicable Fields: Filtration for air, gas and hydrophobic chemicals
PTFE membrane possesses extremely strong chemical compatibility
It can Filter most of the organic solvents and strong corrosive chemicals
If 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
