LifeASSURE™ PDA series filters combine two asymmetric polyethersulfone (PES) membrane layers with Advanced Pleat Technology design for a robust filter optimized for high throughput and fast flow applications.
LifeASSURE™ PDA Series filters incorporate two layers of polyethersulfone membrane. The upstream layer is highly asymmetric and provides optimized prefiltration capacity for the downstream layer that contains a robust, centrally located, retention zone. Both membrane layers are asymmetric and together result in a filter with multiple filtration zones providing extremely high contaminant capacity, fast flow rates and reliable sterilizing filtration performance.
