MICROPES filters are absolute-rated polyethersulfone membrane PES filters designed to provide increased bacteria, virus and particle removal at high flow rates, with extremely low pressure drops. All parts are sealed by hot welding technology without any chemical binder.

MICROPES combine the benefit of both a pre-filter and final filter in one device to provide reliable and consistent performance. MICROPES cartridges incorporate an asymmetric polyethersulfone membrane that delivers high level of filtration performance, stability and service life in demanding process conditions. The PES membrane is permanently hydrophilic, with broad chemical compatibility and extremely low extractable levels in a wide range of fluids and applications.
