General Service Grade
General Service Grade Double Layered PES Membrane Filter
Cartridges are custom configured to increase surface area and
give maximum throughputs for general service use wherever
a membrane filter is required. DPS polyethersulfone (PES)
membrane filter cartridges require fewer changeouts and are
configured for maximum solids holding at the rated pore size,
thus lowering the cost of filtration. DPS filter cartridges are flushed
with high purity water to remove manufacturing debris.
