PESA - Single Layer Polyethersulphone (PES) Cartridge Filter
Masterfilter PESA filter cartridges feature a unique single layer, asymmetric hydrophilic polyether sulphone membrane. This membrane is characterized by excellent throughput and higher durability in many applications such as pharmaceutical and biological filtration and beverage filtration such as beer and wine. Higher flow rates than any other sterilising grade filter cartridge offers, so Masterfilter PESA filter assures thereby the most economic design of filtration systems.
